How To Start Drilling For £8K
Clive Bailye’s seed drill of choice is his 6m John Deere 750A , which has been used exclusively for 3-4 seasons. Last year, with an increased acreage, the founder and publisher of this Direct Driller magazine thought a second seed drill was necessary. Having just the one machine was a risk and in a difficult season would mean drilling was delayed. He looked around and found a good condition Horsch CO6 tine drill advertised in Germany.
Words and pictures by Mike Donovan
After delivery he rebuilt the coulters to a narrow profile so as to reduce soil disturbance. He says the tine drill is very useful driling after straw crops such as osr and also through the straw on second crop cereals.
Buying the drill from a German farmer was not particularly complicated, and provided him with a higher spec machine than Horsh sell in the UK. The seed dart tyres are much wider, and the machine is fitted with blockage monitors as well as full width front packers and also a liquid fert application system.
A sheaf of photos were taken, and Clive then asked for some of specific parts to show wear. The deal was done at under £5,000 which Clive says is the market value of these machines which are too large for small farmers to buy. Original owners like to buy new and sell when the machine is still in good condition.
Narrow tines with wear tiles
@Clive knew he wanted to make changes, substituting the Horsch tines and coulters for something far narrower, and has ended up getting his own design of tine made, which has a wear tile made from Ferobide, far harder than tungsten. The drill is on the farm primarily for osr and 2nd crop cereals drilled into chopped straw and the 25cm spacing is okay for these crops.
Comments on Clive’s on-line forum, TFF, said the drill many not be so good with beans, as the slot is a mere 12mm wide. And in barley the spacing may well be too wide as it needs to be thick. Clive points out that the seed pipe can actually be a bit wider than 12mm as it is in the shadow of the point. It would be good to have the option of using it for beans.

Getting around the German instructions
The Horsch came, of course, with a control box and instructions in German. More on-line discussion revealed that English instructions were available on the Horsch website, and another explained that Horsch was sourcing some of these parts from Agton in Canada anyway. Zealman from New Zealand explained that the button marked with callipers should be held down for around 5 seconds. The menu is where you adjust the tramline sequence, valve layout and row numbers.
Ball hitch is a continental standard and provides a positive connection between tractor and drill
The Stocks Wizard has a rotor modified for Avadex which otherwise leaks everywhere
A Stocks Wizard is on the back of the drill and used for Avadex. Here again the knowledge of actual farmers is helpful. Alistair Nelson warned that the rotor and the surrounding shroud need to be changed, and he got good advice “from Rick at Stocks”. Clive has the same setup on the 750A and says that the Avadex leaks everywhere unless the modification is made. The drill was acquired and modified in 2016 and the results have been excellent.
The machine went through the residue without many problems and having the second drill has meant more timely planting. Clive has shown that moving into No-Till is not the expensive exercise so many farmers think it might be. The total cost, after modifications which included replacing all tines and coulters, was under £8,000.

Farm Manager Seeking Regenerative Role
A practical and innovative farm manager wishing to go beyond sustainability seeks a hands-on position to focus on clean and resilient food, fibre and energy production; soil restoration and natural capital enhancement.
What’s in a Name?
Welcome to the 5th Anniversary issue of Direct Driller / Normal Farming magazine. When we started the magazine, we really didn’t know what to call it. We knew it should focus on soil health, reduced cultivation, conservation agriculture (remember when it was called that), sustainability, efficiency and profitability. Lots of good words and I’d hope we have done well to sticking with those goals over the past 2000 pages of content. But that also gave us a lot of options for a title.
No-Till farmer already existed in the USA – so that was out, as was TCS from France. We put about 20 options up on a white board. It’s fair to say that none really grabbed us, but one was Direct Driller. It referenced more the machinery than the practice and that was our main reasons for not loving it. Because, while the right machinery is critical, we have always believed that to change anything requires a mindset change first. “Mindset Magazine” though didn’t sound a lot like farming and also now exists. Zero-till, Reduced tiller, Zero tiller, Conservation Farming, Regen Farmer were all considered too but nothing grabbed us.
When considering such creative questions, beer should be used to help come to a decision. It didn’t really help, in this instance, but as always made the process more enjoyable. After a couple of weeks, we settled on Direct Driller Magazine. We knew that most of the farmers who undertake this process will be using a direct drill of some sort, it seemed like common ground for all. The magazine was born.
You will see from the front cover we have changed to “Normal Farming Magazine” for this issue. We aren’t changing the name permanently,
mostly because this is an even worse title. However, we wanted to highlight just how much farming media and farming attitudes have changes over the past 5 years towards regenerative farming.
We often say the reason we started the magazine was because we were told there was not room for a niche publication that only focused on
regenerative agriculture. We were in a unique position to be able to break new ground and launch something without a solid business plan behind it. This was at a time when companies were saying the print media didn’t have a future and smaller publications were going to digital. Yet now all the mainstream printed magazines are now full of regenerative content. They are all pivoting fast to this new normal. ESG,
sustainability, biodiversity and carbon credits are talked about everywhere.
And this is our point behind the title. Regenerative farmers, like yourselves, have become trend setters, not followers. You are not outliers, those weird farmers who do things differently. You are now “normal”. I realise some of you are going to be quite disappointed by this new status, but I’m afraid it’s the truth. Those farmers who fight change are now seen as outliers, fighting for a past that clearly just doesn’t
work without governmental financial support.
They are now realising they have to change, although that change could also be to move even further away from conservation practices. An odd consequence of what the government is trying to do. Regenerative farming is becoming the new normal – although with a long journey and a lot of learning still required. This new normal means this magazine will keep growing and growing. We never thought it would get to the size it has, but we see no reason why it won’t eventually have more farmer readers than anyone else.
Direct Driller magazine today, is the fastest growing agricultural magazine, created for and by farmers. Giving voices to those farmers who wanted to change and have not only changed their farms, but also influenced hundreds of other farmers to take steps that they would not have done without their support. This is something for regenerative farmers to be proud of. I wrote an article in Issue 14 about the 3.5% rule. We have seen this change in farming being driven by farmers themselves.
By reading this magazine, by going to Groundswell (and now Down to Earth as well), we have created a change in overall farming attitudes. Now everyone is reading about regen ag, even if they don’t read this magazine. For just one issue – here is to being “normal”. Embrace it, tell your nonfarmer friends about it and profit from it.
Thank you to everyone who has helped make this magazine what it is over the past 5 years. Raise your glass to the next 5 years over a Xmas drink with your family and friends.
Merry Christmas and a Happy New Year to all our readers.
Featured Farmer – Harry Heath
Arable & Pig Producer – Newport Shropshire
200ha Owned (Wheat / Barley / OSR / Sunflowers / Beans)
100 Sow Indoor/Outdoor Herd
Our arable business has always traditionally been a poor relation to the livestock enterprise. It has however dutifully had the important task of growing combinable crops to feed the hungry mouths of a 600 sow herd producing 17,000 pigs per year, at least this was the case till very recently. Market volatility and spiralling input prices ultimately were the start of us questioning the status quo in 2021 and it didn’t take too long to realise that our business needed to head down a different path.
Big changes have happened within the last few years, with the biggest being the exit from the indoor pig industry and the move to put agroecology at the centre of everything we do on the farm.
Before the pigs were the dominant enterprise on the farm, the arable land was farmed intensively with a three course rotation of potatoes / sugar beet and wheat. This, alongside a routine use of power harrowing and subsoiling took its toll in leaving our sandy soils prone to slumping and when tested scoring poorly in many other areas of soil health.
Our move to focusing on soil health started in 2018 with a change agronomist. We are extremely lucky to have Ed Brown (Head of Agroecology for Hutchinsons) as our agronomist and I have no doubt in my mind that he has been pivotal to our business in challenging what and more importantly why we do things. We were also kindly asked to be the national agroecology site for Hutchinsons as part of their Helix Farm network. Undoubtedly this has assisted in us running trials to find out what works and more often than not what doesn’t work on our farm. Trials and testing are now the cornerstone for how we make change whilst not exposing ourselves to additional risk.
One of the first changes was doing the thing that everyone told us not to do, which was to buy a new drill. This was in my eyes a necessity, as we had no choice but step away from the combination drill if we ever hoped to start and build better soil structure. We bought a demonstrator 750a and swiftly signed up to an operators course hosted by Simon Chiles. Straight away this gave us confidence that was needed in such a radical change in how we established our crops. The autumns of 2019 and 2020 allowed us to cut out teeth in less than ideal conditions, but the disappointment of slightly lower yields were eased by lower costs which kept margins at parity. Nitrogen rates are starting to come back slowly (circa 20%) but it was only relatively recently that we brought legumes into the rotation and have now started to implement other tools such as foliar N and SAP Analysis to look at improving our efficiency further.
No one really can prepare you for the change in mindset required when going down the regenerative route. From ignoring how the field looks after direct drilling to ignoring the itch of recreational tillage, it’s been a learning curve every step of the way.
Getting living roots in the ground for as much of the year as we can, feels right in line with all the other changes we’ve made. We grazed our cover crops with sheep last year and we’ll look to repeat this again next spring. It’s been our first season this autumn drilling everything directly into catch crops. The biggest benefit to date is how well the ground walks even after the monstrous deluges of rain that we have had in previous weeks.
We are now three years into using untreated home saved wheat blends which seems to be assisting in lower fungicide usage as well as maximising genetic diversity within the crop. Companion crops of buckwheat and clover are grown with the OSR and a further drive to look at how best to use bi and poly cropping will begin again in the spring.
Our nemesis on the farm is undoubtedly herbicide resistant ryegrass. In a 5-6 year timeframe it has spread to a number of fields on the farm whilst we figured out transmission routes and resistance patterns. Now we are taking a much more robust approach to the weed. Firstly harvest hygiene is a number one priority with the combine being blown down with a compressor after every field. A chaff lining kit has been fitted to the combine in an effort to reduce weed seed return on either side of the swath. The one remaining change of the year will be to install a water treatment plant to clean up our borehole water and make it more suitable for spraying and biological amendments.
Our main investment this season has been the move away from the John Deere 750a to a Horsch Avatar. We saw clear benefits from last year’s demonstrator with a heavier closing wheel, more flexibility of drilling multiple products and easier calibration. The big move agronomically was to place liquid products down with the seed. We bought a second hand Opico Nitro Jet front tank and bought the rest of the kit from Simon at S&K Sprayers. With Johnson-Su bioreactors and vermicomposters in the shed, it has been great to make a start this year with placing these products down with the seed in furrow or as a seed drench. The OSR went in a little later than we had planned this year (Circa 21st August) but the addition of liquid fertiliser, seaweed and liquid fish seemed to improve crop vigour compared to control plots without any.
Change has definitely brought about new opportunities for our farm in a way that I could never have anticipated. The move to direct drilling has really helped us grow and expand our arable contracting by helping other local farmers focus on improving soil health.
From a previous life of out of hours breakdowns and alarms the initial prospect of being livestock free on the farm had an obvious appeal but the need for spreading risk and retaining a diversified income stream would always win out for us especially with modern livestock buildings with few options for alternative use. We made our decision to move from intensive to extensive production.
One thing that always struck me as odd with our previous pig enterprise was that meat eating quality was barely given a second thought. It was always increasing growth rates, reducing feed conversion or improving breeding performance but never actually the thing that ultimately mattered, what the consumer thought when eating what you produced. We were very lucky to meet a chef in London who also shared this same thinking and it didn’t take long to form a joint venture and make plans on how to take the pigs forward in the future. For now this venture is in its infancy but it will be great to see how we can best integrate the pigs with the arable so that both enterprises benefit from each other.
Like so many readers of this magazine I’m always pleased to see it land on the doormat. This inevitably leads to me pouring over its pages for the following few weeks when chance allows. I’m continually inspired by how many other growers are reducing their reliance on inputs, focusing on profit over yield and showing how regenerative farming can be a sustainable lower risk model for farmers to adopt.
With some many other changes on the horizon such as ELMS, carbon and biodiversity trading and the full effects of Brexit and trade deals yet still to be felt I feel we are as aligned as well as we can be for challenges that lay ahead.
The curious case of disappearing nitrogen
Written by James Warne from Soil First Farming
It seems everyone is doing ‘regen’ these days. There is a lot of confusion and miscommunication around what it means. I was at a meeting recently where I heard someone proclaim that their arable business was carbon neutral even though they were still ploughing, combi-drilling and using an average of 230 kg/ha of nitrogen every year. I wondered which of the many carbon calculators threw out that spurious result, or the quality of the data fed into it?
Whilst on the subject of nitrogen, there is lot of talk amongst farmers and growers over simply reducing nitrogen rates. Every grower on social media is now growing record yields of wheat with zero inputs. It’s the latest form of alchemy, reduce inputs and conjure up something for nothing, it’s origins probably stem from Trussonomics.
But is it possible to reduce nitrogen by 80% and maintain output? Can you really grow 10 tonnes/ha wheat crop with only 40kg of applied nitrogen?
Research suggests the total nitrogen requirement for a wheat crop is somewhere between 280-360 kg/ha. That is for all the biomass of the crop, above and below ground. A 10 tonne crop of 11% protein wheat removes 190kg N alone. If we are reducing the total applied nitrogen, where is the balance going to come from?
If we consider the nitrogen cycle (below) for a moment it is clear that aside from inputs there are only three other sources of nitrogen the plant can rely on;
1, Biological fixation
2, Deposition from the atmosphere, mainly rainfall
3, Mineralisation from Soil Organic Matter (SOM)
(reproduced from Crop Nutrition & Fertiliser Use, John Archer, 1985)
Biological fixation and atmospheric deposition combined may contribute anywhere between 0-40 kg nitrogen per hectare per year. Biological fixation is carried out by soil-dwelling, free-living, nitrogen fixing bacteria, such as species of Azotobacter & Bacillus. These free-living bacteria are not to be confused with the symbiotic species (Rhizobium) that associate with legumes.
As with all biological functions the bacteria need water, temperature, oxygen, carbon and a suitable pH in which to thrive. Remove, or reduce, any one of these requirements and they will stop reproducing and go dormant.
Mineralisation of SOM is also a biological function and as such has the same requirements given above. The potential nitrogen contribution from a typical arable mineral soil with low organic matter maybe as much as 50kg/ha in a good season, but it depends upon rainfall! Organic soils and those high in SOM maybe able to release more than 200kg per hectare of nitrogen.
However, having a good biologically active soil is only part of the story, the crop still needs to be able to access and utilise the nitrogen with high efficiency. This relies upon soil structure and crop rooting to explore the soil reserves. Good crop nutrition, especially access to magnesium to allow maximum solar radiation interception, and sulphur to fully express amino acid and protein synthesis.
Steve and I have been conducting our own trials, on-farm, and independently, over several years now and we have no doubts that it is possible to reduce the total nitrogen applied, increase nitrogen utilisation considerably and maintain yield. It is important to stress however that it can only be achieved in some very specific circumstances. If you are on a path of raising carbon levels in your soil it seems natural you may want to cut back on your nitrogen inputs, but this may not always be the most logical thing to do.
How Biodiversity Net Gain (BNG) is delivering alternative farm funding
With the farming landscape in the UK changing so dramatically in recent years, leaving many generational farmers facing reduced financial support as well as increased costs, the pressure is really on over how to make land generate a return.
Many farmers today are facing the stark reality of dwindling subsidies, so it’s never been more urgent for farmers and landowners to explore securing long-term methods of creating diversified and sustainable income streams to safeguard their future.
Understanding what is involved in new schemes in practical terms can be challenging and there are many questions around how land used for natural capital projects will impact on a farmer’s core business. This is where Environment Bank can help.
What is Environment Bank?
Environment Bank was established in 2006 and was the first business of its kind in the world to launch Biodiversity Net Gain (BNG) Units. Founded by UK ecologist Professor David Hill CBE, Environment Bank developed a concept where biodiversity net gain (BNG) would ensure land used by developers for building and infrastructure projects would help leave the environment in a better state than before the development began, by providing net gains to biodiversity to meet their legal requirements.
BNG became a mandatory legal requirement in 2021 under The Environment Act, which David lobbied hard to secure in law over a 15-year period. Since then, Environment Bank was awarded £200m in private sustainable investment funding to begin establishing a nationwide network of Habitat Banks (parcels of land) totalling over 4,000 hectares across England that deliver BNG Units.
What is a Habitat Bank?
Environment Bank actively began establishing its Habitat Banks across England in 2021, which is essentially securing a parcel of land that creates a significant uplift in biodiversity. Typically they are created on low-yielding land upwards of 10 hectares in size and can be made up of species-rich grassland, woodland, wetland, mixed scrub or rewilding sites. They provide a secure and long-term income to landowners and a biologically diverse haven for nature, leasing land throughout England to the Environment Bank to create biodiverse habitats that help restore nature, selling the ‘BNG Units’, back to developers.
Ensuring the Habitat Banks don’t impact national farming requirements, Environment Bank looks to utilise the marginal or low yielding land with the Environment Bank only taking a lease interest in the land, so the landowner retains ownership.
Environment Bank can then raise BNG Units on biodiversity uplift which they can use to help organisations meet their biodiversity net gain requirements, removing all risk and long-term liability from the landowner.
Since launching its award-winning Habitat Bank scheme last year, Environment Bank has seen enquiries soar, with over 60 new sites expected to be established in 2023. It is partnering with farmers and landowners – including Tim Easby from Oak Stile Farm, North Yorkshire, and Toby Diggens, from Puddington Moor Farm, Devon – establishing Habitat Banks on their land through its privately funded management scheme that guarantees an income for 30 years.
What type of land is required for a Habitat Bank?
All types of land are considered for Habitat Banks including currently unproductive areas, old pasture and scrubland as well as under-performing arable land. This is across the acreage on parcels of land upwards of 10 hectares in size and doesn’t have to be in one block.
The ecologists work with landowners to establish habitats that work best for their land operations, and which creates the best outcomes for nature in their location. They won’t change the entire face of your farm, they will simply help support the replacement of your existing EU farm subsidies as an alternative use of small parcels of land.
How Habitat Banks benefit farmers
A crucial benefit is that farmers retain ownership of the land. A management plan, contracted to and delivered by the landholder, is tailored to suit the existing land management strategy and sources of funding, as well as ensuring the most tax-efficient solution. Environment Bank pays up to £27,000 per hectare over a 30 year period for the management and lease of the land, as well as a generous welcome bonus.
Being fully funded, Environment Bank typically arranges the lease and management payments within 20 weeks of registration, and covers all costs for establishing and managing the Habitat Banks, extending to legal and tax advice where appropriate. It has a ready-made solution, so unlike brokerage models, farmers do not have to manage the complex implementation process or take any of the risk of the scheme failing. All of that sits with Environment Bank.
Farmers receive an on-boarding fee, their first year’s rent upfront, and then annual payments which increase with inflation for the 30-year term.
The goal of Environment Bank is to establish a network of Habitat Banks in every area of England to restore biodiversity and help farmers achieve this all whilst protecting their assets, making it a win-win situation for hard-pressed farmers.
There are many benefits to the scheme. It is uniquely designed to fit within existing farm enterprises including the production of food, tourism enterprises and other business streams, as well as alongside the government’s new Sustainable Farming Initiatives (SFI).
The management schedule on a Habitat Bank
How the land is managed depends on the management plan agreed with the landowner and how the Habitat Bank will work alongside other farm enterprises. It will be monitored regularly by ecologists at Environment Bank, and the progress reported back annually to the local planning authority or responsible body as part of their BNG obligations.
For grassland, for example, each year, the fields will be closed off during flowering season and the land keeper can take a hay cut once wild flowers have bloomed. In the autumn, the ground can be used for grazing, before livestock come back off the land again in March to allow the flora and fauna to bloom again, attracting rare species including birds and insects.
Native shrubs are often planted around the perimeters of the grasslands and livestock fenced out from the area to allow new shrubs to grow. Once established, the fencing will come down and the livestock can graze in the open habitats. Ecologists may put in ponds and wet scrapes if required to attract bird species such as endangered curlew and lapwing to breed and encourage more rare species of wildlife.
The land is managed in this way by the landowner – or generations of landowner – over a minimum 30 year period to allow for a fully biodiverse habitat to be established.
What do landowners involved in the scheme think?
Speaking of the establishment of a Habitat Bank at Oak Stile Farm, North Yorkshire, Tim Easby said: “We are delighted that Oak Stile Farm is hosting a Habitat Bank so that we can do our bit to enhance local biodiversity.
“We took ownership of this former dairy farm over 20 years ago and have begun to enhance areas for wildlife with sections of woodland planting and new hedgerows. We have always wanted to do more and Environment Bank’s Habitat Bank scheme allows us to enhance large areas of our grasslands for wildlife at a scale we couldn’t do before in a financially sustainable way.”
Many landowners and farmers are signing up to the scheme, and there is none more passionate about the benefits of Habitat Bank creation than one of the first farmer’s to sign up to the programme, Toby Diggens from Puddington Moor Farm.
“Being involved in such a ground-breaking project was important to me, as it’s one of the ways we can contribute to restoring nature and help reverse the environmental crisis,” he said.
“There are so many benefits to protecting wildlife and nature fundamentally, but this partnership also allows us to guarantee an income for the next 30 years on land which we would have to conventionally farm very hard to see any profit.”

Farmer Focus – Rob Raven
After a very easy and early harvest, followed by a few stressful weeks of unbelievably dry conditions when most drilling and land work was impossible, we finally had the autumn we had all been waiting for. For us the rain fell little and often from mid-September until the beginning of November, when the heavens opened. By then we had comfortably drilled a larger than usual spread of winter crops in pretty much ideal conditions. Casualties have been cover crops and early oilseed rape on heavy land, both of which we chose to plant a reduced area due to the drought in August and early September.
On a lighter block of land we did catch a single shower in late July, which allowed us to very quickly plant some cover crops after winter barley. These really suffered through August and early September, but they survived, and with such beautiful growing conditions in October they are now looking good, if a little brassica-heavy. The balmy autumn also allowed us to continue grazing marshes until 1st December, and leave the cover crops more time to bulk up. In September I was seriously concerned about how we would keep the livestock fed through winter, but the situation is now looking a lot more relaxed.
Long-term DD land has coped with the wet November very well and walks clean and firm. Any land that had been moved is now very soft indeed. Unfortunately, the dry autumn means there was very little chit pre-drilling, even by late October. Pre-em effectiveness has no doubt been compromised as well, so it does not look like the cleanest year. There was also no mole draining, as I felt the clay subsoil was not moist enough to hold a mole. However, we used the dry conditions to get some low disturbance subsoiling done on land which had historic compaction, which I hope will pay dividends.
I am a bit agnostic about the LD subsoiler. Last year we made one and used it to great effect on some “new” land which had been previously worked to death by a TopDown at 8” every year and was yielding very poorly. The top 8” were solid and airless like concrete, below that it was lovely. We used the LD subsoiler at 10”, then planted with a direct tine drill and had some fantastic crops, and have been able to DD the same land this year into lovely structure. So I think it is a great tool for the right situation, and particularly for land in conversion.
The success with the LD subsoiler was too great to ignore, so I have used it this autumn for some trial areas on long-term DD land which is yielding OK, but has plateaued somewhat. I really hope the trials do not prove to embarrass the untouched land, or it is going to really mess with my convictions (and my status at Direct Driller!), but I do think it is correct to constantly challenge everything, especially our own ideas. Ask me next summer how it went. I am generally pleased with my DD winter cropping, and spring beans seem to do well, but no-till spring barley does seem to underperform when the conditions are against it. I am in charge of some land which was in the last year of a sugarbeet contract, so we planted some spring barley into cultivated land after beet this year.
I have to admit it outperformed the DD stuff by a large margin, despite being on light land in a super dry year. Again, this is too much to ignore when barley is £275/ton! I have now stopped growing sugarbeet everywhere- even at £40/t I can’t bear the long-term soil damage I have seen from the heavy machinery in the middle of winter. But I do want to make spring barley perform consistently and talking to other DD’ers I am not the only one who finds this crop a particular challenge. So as a (fairly large) trial, we have broadcast cover crops and incorporated them with a shallow cultivation at about 3”, leaving a rough and slightly corrugated seedbed, with cover crop growing out of it.
I hope these corrugations will weather down over winter and give us some tilth to drill spring barley in to, rather than the rather flat, solid and cold surface we were getting from no-till cover crops. On one block we achieved this “cultivation” with a drill fitted with wide Bourghault VOS points, set deeper than normal and the harrow removed. On another we used a set of discs, and on another a TopDown. Again I will let you know how it goes.
For a Direct Driller article, this column seems to contain a lot of talk about cultivation. My viewpoint has not changed and I have no intention of moving away from my low-disturbance farming and all the benefits it has brought. However I feel confident that biologically active soils with cover crops could cope with very occasional interventions such as those described above without a great deal of injury, quickly rebuilding the connections lost and filling the space created with living root. And if this slight modification to 100% DD does significantly improve yield for the same crop inputs, without messing up the land, then I for one need to know about it. Tin hat on!
Food vs Feed
Everyone reading this magazine is likely to be aware of the enormous environmental (and dare I say health?) benefits of pasture-fed meat. I am lucky enough to produce, sell and consume some of it myself, and do it with the greatest of pride and pleasure. However, we also know that in contrast, the vast majority of the world’s beef is produced by feeding grains to cattle in enormous concentrated feedlots, with a huge cost to the climate and environment (and again health?). I am firmly of the belief that farmers should grow whatever they like.
However, anyone claiming that their farming system can help save the world through GHG reduction and carbon sequestration should be ready for a bit of scrutiny over the downstream effects of their production- particularly if they are hoping to get paid for such climate friendly farming. It would be quite possible to be a direct driller and to produce 100% feed grains, and for all the carbon saved and sequestered on farm to be belched back in to the atmosphere on the feedlot. With this in mind, and with my conscience pricked by this thorny issue as I get old and soft, I have given myself a personal challenge to grow crops for human consumption as far as possible.
Wheat: As for wheat, we are not on classic milling wheat land, and the extra Nitrogen required to hit the required protein would run counter to our goal of reduced inputs, so full spec bread wheat is out. Instead I have been growing a combination of low-protein milling varieties and Group 4 soft wheats which have gone for human consumption with a small premium over feed, at no extra cost to us. We have also sold some high grain quality feed varieties into a niche market for malted grains.
Barley: Spring malting barley on heavy land is now much easier to achieve thanks to some great varieties and some high N contracts. Winter malting barley is more of a challenge, due mostly to problems controlling wheat volunteers in a no-till scenario. We are persevering and this year after a very shallow discing of wheat stubbles, followed by patience, glyphosate, and finally ULD disc drilled Flagon, we have some clean looking barley.
OSR is pretty straightforward.
Beans are a struggle due to Bruchid beetle. We don’t use insecticide to try to control it, and past experience suggests it doesn’t work anyway. The cosmetic damage the beetles cause make the beans unsaleable for human consumption and consequently downgraded to feed, even though they are perfectly fine to eat. I don’t have a solution for this, and as beans are an essential part of the rotation I will have to press on in the hope that one day consumers will want beans with holes in them, as a mark of their true regen heritage. In the meantime, any feed beans we produce are seriously low input, great for the soil and the invertebrate population, and they do at least displace soya, which must have a higher environmental footprint.
Specialist crops: we grow a variety of specialist crops such as linseed, lupins, lentils, and peas for direct sale to some fantastic customers. All of them have had some good results, but consistency is difficult (the dull 2021 harvest meant the lentils never ripened for example), and storage and handling of small volumes is always an issue. However I do much prefer growing for a particular end market which values the provenance of the product, and it is always an interesting challenge to grow something a little out of the ordinary! I hope by continuing to support these markets they will grow, and allow these crops to fill a more significant part of the rotation.
From the Sea to the Soil
Inspired by history for the future of farming
Using fish in arable farming is not a new phenomenon. The practice can be traced back to the ancient Roman empire on this side of the Atlantic, and there are stories of Native Americans showing the Pilgrims how to grow corn by planting a fish with each seed. It may have all started as a happy coincidence when farmers observed that plants performed better when decomposing fish were left near them, but thanks to science and research, we now have a good understanding of how fish material positively affects crops and the soils that support them. Mindful of the Farm to Fork Strategy in Europe which is looking for a 20% decrease in the use of chemical fertilisers by 2030, Dr Geraldine Fox and the team at Pelagia has developed the UKs first liquid fish hydrolysate approved by Animal & Plant Health Agency (APHA) for use as an organic soil improver which is also approved as an input to organic farming systems by the Soil Association. Sea2Soil revives a traditional farming method that time has forgotten, one which aligns with the path of regenerative farming.
Pelagia has an over 100-year history of utilising fish and fish by-products from human consumption processing to produce valuable and highly nutritious feed materials. Long before circular economy waste management and waste valorisation became buzz words, Pelagia has been recycling 100% of fish waste to produce economically important products.
In 2019, our processing plant in Bressay on the Shetland Isles expanded its operations and obtained a licence to utilise the by-products from Scottish salmon farms with the aim of zero waste from this industry. Here in the UK, this type of product would ordinarily have gone into anaerobic digestion as a feedstock where the beneficial nutrients and characteristics of the hydrolysate are somewhat diluted by other stock materials. Our goal is to retain the integrity of the rich source of essential amino acids, fats, macro- and micronutrients contained in the hydrolysate and offer it in as pure a form as possible that can be easily incorporated into many formulations.
Sea2Soil acts by feeding your soil bacteria, in turn converting the macro and micro-nutrients contained into a form that is more readily available to the plants. We have evidence that Sea2Soil, which is naturally high in fat, promotes the growth of fungi, which are hugely important in soil root systems, performing important functions within the soil in relation to nutrient cycling, disease suppression and water dynamics. The improved microbial populations also feed secondary and higher-level consumers like protozoa, nematodes, and earthworms, which work to improve soil structure by aerating the soil leading to better root development and reduction in abiotic stress. These macro-organisms also contribute to improved nutrient availability within the soil through excretion providing additional bioavailable nutrients to the growing plant.
For the past 3 years we have been refining our process to produce an organic soil improver that is affordable, delivers on yield responses, reduces reliance on chemical inputs and is farmer friendly. We have resisted the temptation to call it a fertiliser, because it is so much more than that. We see it as a prebiotic for your soil leading to:
- A healthier soil environment;
- Increased crop health;
- Reduced reliance on chemical fertilisers; and
- Promotion of a regenerative ecosystem, where the environment and its living populations can renew and recover from damage and stress.
Farm trials began in 2020 across various locations within the UK and on various crop types such as wheat, barley, oilseed rape, oats and beans. The aim was to identify how and if yield performance was affected and to identify any areas of further product development. We found that yield was either maintained or showed an increase, but what the results highlighted was that return on investment was higher, due to the reduction of chemical inputs. We continue to develop this knowledge portfolio testing its effects in vineyards, orchards and Christmas tree farms as well collaborating with various research groups.
Paul Davey runs Girsby Farm Services, a progressive agricultural contractor with a commitment to providing high quality crop production services to customers with interests in conservation and regenerative agriculture, and has been using Sea2Soil on his land in Lincolnshire.
Paul has seen first hand the positive effects of our product: “The dry conditions this last spring and summer presented challenges in a number of different crops, especially maintaining plant nutrition and managing the associated stresses. There were visible benefits for maintaining growth in the herbal ley established in May which received a 10 lt/ha of Sea2Soil application through fertiliser streamer nozzles in June. This application stimulated a good deal of growth within three weeks in a very dry time. Two applications of 10 lt/ha of Sea2Soil on the spring beans during the same dry spell improved the canopy growth of the beans and removed the chlorotic symptoms of stress, significantly improving the verdancy of the plants.”
Looking back not even a hundred years, it’s easy to see how rapidly the industry has favoured chemical enhancement over natural counterparts – a change which we all know can be put down to countless societal and industry-specific pressures. None of us knew it at the time, but introducing chemicals was a case of solving one issue while causing many others, including topsoil erosion and the destruction of soil health which in turn has been detrimental to our crops. Sea2Soil can positively contribute to the recovery of soil health, by improving soil biology and soil microbial populations, hastening the restoration of our topsoil and improving overall plant health.
Sap analysis proving valuable for large, diverse farming business
In the final part of our series on sap analysis, Mike Abram talks to a farming business that’s incorporated sap analysis into a wide range of cropping
Extensive sap analysis, first in trials, but increasingly in commercial practice is starting to change the way Cambs Farms Growers, part of G’s Growers, is managing its wide range of cropping.
Farming around 4000ha of land at the home farm in Cambridgeshire the business grows Little Gem and Iceberg lettuces, celery, potatoes, onions, wheat, barley and maize for anaerobic digestion.
A key target for the business is to reduce its use of inputs without sacrificing yield, says Harry Winslet, Future Farming Manager for CFG. His team conducts trials looking at how to reduce fertiliser and pesticide inputs, as well as how to implement other regenerative agriculture practices with the help of Ian Robertson from Sustainable Soil Management and RegenBen’s Ben Taylor-Davies. Successful practices are then rolled out and scaled up into commercial production.
“We are essentially an in-house research group,” says Mr Winslet.
To meet that business objective of reducing inputs, Mr Winslet says he needed to better understand what was going on in the crop. That’s where sap analysis came in – starting with sending old and new leaf samples to NovaCropControl in 2019.
“What we were hoping to achieve was not necessarily the fine detail about every nutrient and every sample but understand what the broad challenges on the farm were.
“Do we have excesses in one nutrient or deficiencies consistently in another, to begin to understand what the whole farm trends were, and then to try and correlate that to crops that are growing well, tasting good with good shelf life, or to crops that are not performing well, or have pest and disease challenges,” he explains.
After four years of an extensive programme of sap analysis sampling the business has now identified nutrient markers for each of the crops that drive either good or poor performance, Mr Winslet says.
“So now when we get a sap test back, we are able to home in on those markers.”
Most growers using sap analysis will understand excessively high ammonium is a marker for likely pest attack, and high nitrate content leaves crops at risk from disease, but the research by CFG has found high potassium is a marker for poor crop performance in celery, while excessively low phosphate generally is challenging early in salad crops.
Crops are tested fortnightly typically. For lettuce and celery that means three to four times during the growing period, while wheats are measured from the autumn through to senescence. A lot of the samples are for trials purposes, but representative samples from different varieties and soil types are used in commercial crops.
“This year we took over 1000 samples for sap analysis, at a cost of around €12.50 per sample.”
That investment is paying off, Mr Winslet says. “We wholeheartedly believe in the results we are getting and the changes we are able to make off the back of them. The data we have collected over the past four season has allowed us to identify some of our challenges and make significant changes to our agronomy to try to tackle them.
“With size of the business, if we can make significant reductions in fertiliser or improvements in yield, or preferably both, the return on investment is huge.”
For example, in wheat, sap analysis is providing the evidence to make significant changes to micronutrient applications.
“Across the farm, we were consistently finding that we are probably over applying manganese and under applying others like boron, zinc and copper.”
As a result, the whole farm practice changed from applying 3kg/ha of manganese and 3kg/ha of magnesium every three weeks during the spring to tank mixtures containing copper, boron, zinc with higher rates of magnesium and lower rates of manganese. Chelators such as fulvic acid were also added to try and improve the uptake of those nutrients.
“We saw a really positive yield in our wheat crops this year. That’s not necessarily directly linked to those changes but later in the crop we saw significantly more balanced sap and tissue tests than before we made those interventions.”
Visual observations during the season on a trial area not treated with any fungicide until flag leaf suggested the crop was also free from disease, but, in a dry season, Mr Winslet says it is difficult to draw any immediate conclusions on whether the balanced nutrition was a factor.
“The hope is that we will be able to reduce our fungicide inputs.”
His team is now developing an automated Excel application that will generate a bespoke nutrient tank mix for the farm to apply from the sap analysis results and the crop’s current biomass.
The biggest challenge CFG has faced, in common with other trying to use sap analysis, is the inconsistent delivery to NovaCropControl’s laboratories in the Netherlands.
Prior to the new customs rules for exports from the UK began in January 2021, Mr Winslet says he was able to send leaf samples to NovaCropControl on a Wednesday and receive results on a Friday.
“Now there doesn’t seem to be any rhyme or reason to when parcels get to the Netherlands – we’ve had samples that get there the following day, and then others that have taken two weeks.”
That kind of delay makes trusting the data, especially around nitrogen, more difficult, he admits, which potentially could hamper some of the decision-making in key crops and the business aim to pull back on applying artificial nitrogen.
“For example, in celery we are pretty convinced that one of the issues surrounding quality and shelf life is over application of late nitrogen.
“But if you have a sample that has sat in customs for two weeks and you’re trying to interpret a total nitrogen versus nitrate reading, how sure of that result can you be?”
When the sap analysis results have been timely, the business has been using them to help improve nitrogen use efficiency in the celery crop, he says, finding it is important to have an ample supply of sulphur and magnesium in the crop, alongside a steady supply of nitrogen to build biomass.
“If we can ensure that more often than not, we find we have a very successful celery crop.
“What we are ultimately aiming to do is to reduce our nitrogen inputs based on the results of the sap analysis.”
Experience and visual observation are helping them deliver some of that nitrogen saving, but timely sap analysis results would make decision-making easier and give extra confidence, he says.
One big change the business is making is to switch from ammonium nitrate to injecting liquid urea on 80% of the celery crop.
“Moving away from ammonium nitrate is a big part of our future farming agenda. We would rather not use it because of the negative impacts on the very biology we are trying to build in our soils.
“But we didn’t want to do that at the expense of the crop having the uptake of nitrogen it needed.”
Sap analyses and biomass assessments comparing the two have shown no difference in uptake, and given the confidence to make the switch starting next season, he says. “The hope is the other salad crops will follow once we have built up the same confidence.”
Ultimately, Mr Winslet is hoping the entire group adopts the sap testing strategy on farm, both on the UK farms and their farms in other parts of the world.
“On our farm, it is initially about validating the trends we are seeing, and become better at analysing the results, and either applying or not applying nutrition as a result.
“We’ve already starting to move away from being a farm that is largely applying bulk macronutrition NPK products to one applying small amounts of micronutrition.
“The hope is we will get better at that and build the confidence to apply less and less nitrogen and phosphorus fertilisers and balance our crop health to the point we can cut pesticide use because the crops are nutritionally balanced,” he concludes.
Pasture and Profit in Protected Landscapes Programme
Pasture and Profit in Protected Landscapes is a free, farmer-led programme of farm walks, events and webinars open to everyone farming in the Protected Landscapes of Surrey Hills, High Weald and Kent Downs. The programme is being run by Pasture for Life in partnership with the Protected Landscapes. We believe that farmers learn best from other farmers, so over the next 15 months farmers in Surrey, Sussex and Kent are opening up their farms to share how their low input approach to grazing sheep and cattle has helped protect their farm business from the crippling increases in fertiliser, feed and fuel costs, and mitigate the effects of the drought.
From mob grazing to conservation grazing, they demonstrate a range of approaches for managing their land and the challenges and the opportunities of farming in this way. The benefits include:
- Financial gain
- Improved pasture
- Increased biodiversity
- Improved soil health and landscape management
- Reduced (or removed) workload associated with indoor housing
- Reduced worm burden on stock
By joining the programme, you are NOT expected to become Pasture for Life Certified or transition to a 100% pasture-fed or 100% mobile grazing system. The programme is designed to meet your needs and support you, whatever your current system or goals.
Free Pasture for Life membership
When you register for the programme, if you are not already a PfL member, you will automatically receive free PfL membership until March 2024 which normally costs £100 a year. This will enable you to additionally benefit from being part of our engaged and supportive community, as well as the work we do across areas such as the supply chain, marketing and academic research, and access to our forum, which is full of advice and support from other farmers who will often be facing the same challenges as you. You do not have to provide any financial details when signing up, and you can choose whether to continue with PfL membership at the end of the programme.
By registering for the Pasture and Profit in Protected Landscapes Programme, you can also apply to be mentored for up to a year by a farmer with experience of rotational grazing.
We have trained 12 Pasture for Life farmers as mentors across Surrey, Sussex and Kent who have a range of approaches to grazing with sheep and cattle. For instance, some house their cattle over the winter while some leave their cattle out year-round. What they have in common is that they are all 100% pasture-fed with no grain or feed inputs, and all have adopted some form of rotational grazing. Without exception, they find that the way they now farm is more profitable than the system they inherited, that it has increased biodiversity and improved the health of their stock and pasture, and has made their farm business more resilient in times of extreme weather and spiralling costs. The experience has been transformative for them, and they are keen to share their learning with other farmers whether they are just curious to see other approaches or are wanting to change how they farm.
For more information or to register for the programme, please email Sarah at Sarah@pastureforlife.org and she will email you a simple registration form, or call Deborah on 07543286709. Please note you must be farming in the Protected Landscapes of the Surrey Hills, High Weald or Kent to qualify.
Pasture and Profit in Protected Landscapes is funded by the Farming in Protected Landscapes Fund (FiPL) and supported by the Surrey Hills, High Weald and Kent Downs Protected Landscape Partnerships.
Meet a Mentor behind Pasture & Profit
Andrew Lingham, Court Farm Butchery, Rochester, Kent
Andrew runs a 320-hectare mixed farm, with 220 hectares of arable crops – including cereals, various beans, linseeds, millet and heritage wheat varieties – alongside his Pasture for Life Certified 30-40 strong herd of native breed store cattle and around 150 Romney store lambs.
For Andrew, this mixed, integrated system is key to his success. His animals offer a valuable additional revenue stream through his butcher’s shop, but perhaps more importantly, they play a crucial role in building soil organic matter and recycling nutrients. He has very little permanent pasture, and for the most part grazes his animals on cover crops, using a 60/40 rule. In his words, “you don’t let the animals graze down to the floorboards. Let them take 60%, and trample the remaining 40% back into the ground.” This approach, he says, is “far superior” compared to just using cover crops alone, and means the animals are “feeding themselves, feeding the soil, maintaining soil structure and increasing organic matter.” How long he leaves his animals on a crop depends on the conditions – in dry weather they will graze an area for around 3 days, but in wetter conditions it can be as little as 1-2 days to protect the ground from trampling.
“We actually see our animals gain more weight over winter by grazing on our cover crops than we do in the summer off the permanent pasture”, he remarks, demonstrating just how drastically different farming can look compared to conventional systems based on feeding costly inputs to grazing animals over winter. “This is a pretty low-cost system, and by low cost I don’t mean low output, it is truly working with nature. I know it’s an old cliche that’s fairly overused, but the further you get into this the more you can see that natural processes actually work if you don’t interfere with them too much.”
Andrew has always been drawn to doing things differently and questioning the status quo – for example, he started treating his animals homoeopathically in the mid-90s. He now thinks he can bring that questioning mindset to his role as a mentor, for those who are also open-minded to new approaches and wanting to make some changes. “I don’t have all the answers, but I’m happy to be a sounding board and guide people through the approach. And I don’t like lecturing people, but if you’re interested and want to learn, I’ve learnt a hell of a lot and I want to pass this on.”
His approach is certainly working. “My veterinary bills are pretty much zero, and it’s been years since I used antibiotics. Our worming treatment is pretty much just rotational grazing, and the use of some diatomaceous earth and seaweed kelp,” he says, when asked about other ways this approach has benefited his farm. Andrew has particular interest in building both the gut microbiomes of his animals and microbiome of his soil, and speaks to the interconnectedness of the two. One way he does this is by brewing his own microbial treatment, full of beneficial bacteria and fungi for his animals, which is put in their water. This keeps their gut microbiomes healthy and stable, and further inoculates the soil through their waste; another example of his holistic approach having multiple benefits across the farm.
Andrew talks with enthusiasm about how for him, every day is a learning day, grappling with new questions and challenges and thinking through how to approach them. This often sees him tapping into a global network of farmers who are also turning to nature-led, low-input systems. ‘It’s so easy for the current generation to learn if they’re interested. There is so much information available online. In mentoring I see myself as a bit of a guide towards people and resources who have been mentors for me, people across the world who you can tap into and who do actually respond. When they come back and answer some pertinent questions you have, you really feel that you are part of a global movement.”
If you’re interested in being mentored by someone like Andrew, please email Sarah at Sarah@pastureforlife.org and she will email you a simple form, or call Deborah on 07543286709 to register for the programme, and state your interest in getting a mentor. Please note you must be farming in the Protected Landscapes of the Surrey Hills, High Weald or Kent to qualify.
Farmer Focus – John Pawsey
I can’t be certain when you will be reading this contribution to the UK’s formative regenerative publication, but what I do know is that most of you will be about to, or will just have, sat around the Christmas table with your family.
It can be tricky territory. Especially if you are all working together in a family farm situation where life expectations have never been discussed and/or familiarity has bred contempt. It does happen.
I’m not a fan of mirrors because whenever I pass one, a weird old bald man stares back at me. At fifty eight years old and with three young adults between the ages of nineteen and twenty four, I am reconciled to the fact that some kind of succession will have to be discussed as it’s becoming increasingly obvious that the weird old bald man in the mirror is me. Knowing my lot, after a few late festive nights, lashings of wine from the West of France and endless cold turkey sandwiches, my offspring’s future involvement in the family business will be discussed. I need to be prepared.
Unfortunately the days are gone when the reins of any business can be passed onto one’s children just because they have sprung from your loins, or more accurately in my own situation, from Alice’s loins, (I played a small part a few months earlier in the pregnancy, apparently) as we need the best people for the job. But what are the opportunities if your successors don’t necessarily fit the traditional farming bill?
For many of us, having diversified our businesses over the last twenty years, it’s not just about farming, which is a bit of a relief as my one of my daughters whilst hermetically sealed inside a luxury tractor cab, blasted with banging tunes, is quite capable of entering a field with an implement that she has assumed has been liberally greased and adorned with fresh wearing parts by the previous occupant. On exiting the field she has been known to turn around for the first time to discover that she has three punctured tyres and the right hand wing of said implement is imbedded in the field’s sole telegraph pole, or as we call them in the barren wastelands of East Anglia, a Suffolk tree.
When I joined our family company in the mid eighties when all we did was farm, persuading a son or daughter to join a family farming business was considered to be a form of child abuse, but possessing no qualifications due to being terribly naughty at school, I was grateful for any opportunity laid at my door. Also, there was a certain agricultural establishment in Gloucestershire that laughed in the face of scholastic achievements as long as your cheque didn’t bounce. No longer the case these days I’m afraid.
The modern rural business is now able to offer a multitude of opportunities which weren’t available to me in my early twenties, and anticipating a Christmas questioning, I have been considering how to engage my young adults and their various aptitudes, and have drawn up a list of new job titles to tempt them.
The roles are as follows.
An Enlightened Agronomist: a few do exist but the majority of agronomic advisors are still happy to reach for the plastic bottle to cover their backs just in case. We have knocked the confidence out of our farmers with the complexity of chemically based agriculture making us feel unqualified to make even the most basic decisions. It’s like raising the bonnet of a car and on seeing an expanse of plastic you close the lid, leaving the job to someone else because you can’t see any recognisable components. You assume that it no longer contains the internal combustion engine that you have worked on for years. Enlightened agronomists can see though the plastic.
Trial Designer and Data Analyser: we are constantly trialling various agronomic scenarios but often don’t complete the work with any rigour to get meaningful answers, or we just do it for a year and think that the results are good enough. We have been collecting data in terms of yield, crop quality, work rates, soil health and biodiversity but we haven’t layered that information to really understand where the real opportunities are for efficient profitable food production with room for nature. It’s not a full time job but when combined with the enlightened agronomist role, it could be.
Administrator, Book Keeper and Inbox Curator: to free us up to do all the creative things (see above). We need to get out of the office. Although mobile devices have allowed us to de-shackle ourselves from the swivel chair, my life is still plagued by administration. I remember being lectured by someone from our levy body about not being as productive as other European farmers. It’s because I’m spending too much time dealing with nonsense when I should be making better decisions for my business. The only inbox I had when I arrived on the farm was a physical paper one but now I have that and an ever expanding array of digital ones too. No, I don’t want to join your f***ing WhatsApp group!
Contract Farming Massager: although I like to feel that we give our undivided attention to our farmers we contract for, there is always more love to impart. Where agents are involved, our farmers get lots of juicy figures but we need to spend more time keeping them up to date with all the things that we are inventing and trialling on our own farm so they know that we are future proofing their businesses as well as our own. We have also missed opportunities to take on new contract farming arrangements mainly due to the lack of time to pursue them. It has to change.
Crop Polisher and Value Adder: part of the reason for converting to organic farming was to go more niche and make the market rather than take it. But we need to go nicher (is that a word?). The easy wins are to take back some of the processing and added value we give away. De-hulling our spelt, cleaning our home saved seed and mixing seed blends on the farm. Separating our own bi-crops and other multi-species crops. Putting in a bagging unit to direct sell some of our exotics. You are probably all doing it already.
A Roboticist: a role that gets me thinking of the term motorist. Motorists were invented over a hundred years ago and were “a thing” because you couldn’t just jump in a car and roar off. You had to check a multitude of lubricants, learn copious amounts of hand signals and something called double-de-clutching. Nowadays we just drive a car, possibly own more than one and never check the oil. In a hundred years time I suspect that we will just instruct robots, possibly more than one and never check their (vegetable) oil. In the meantime, we need the skills of a roboticist.
And then there are all the jobs that we hand over to the man (it usually is) in the coloured corduroys: an Environmental Designer, a Net Zero Minder, a Carbon Creditor and a Green Washer. All new roles and crucial to capitalise on the opportunities that will be available to us in the coming years. Some expert help will be needed but we should be able to do a lot of the work ourselves. Biodiversity net gain needs to be our net gain and not somebody else’s.
There is an opportunity for a Website Wizard, Social Media Schmoozer and a Brand Manager. Our website is horribly old and clunky and needs immediate attention. You maybe aware that I love a bit of social media, and although @Hanslope on Twitter gets my full attention, @ShimplingPark does not. And then there is all the other platforms that we are blissfully ignoring like TicTac and SnipChit to name but two. Everyone needs a brand manager, don’t they? The above is not a full time role, but an important one if we are to fully engage with our customers.
Although most of our redundant farm buildings have been re-purposed as offices, commercial lets and dwellings, there is always room for improving our offering and so two new roles could be created as a Property Tickler and an Asset Sweater.
The list goes on, and I suspect that reading this you have come up with several more positions of your own. Please do email me your inspired wisdom to email@example.com as soon as you can and they will be presented to my progeny.
You may be asking yourself at this point what any of this has to do with direct drilling? Absolutely nothing. But succession is something that we all have to grasp and if you are not doing so, then please make a New Year’s resolution to do so. For the sake of you and your family.
Wishing you an extremely Merry Christmas, the best New Year and an amazing Harvest 2023
Drill Manufacturers in Focus – Dale Drills
Top Features for Farmers
James Dale reviews the key features and benefits of the Dale Drills range which tick the boxes for his customers.
Like 2021, 2022 has been another very busy year for Dale Drills, with sales of seed drills up on previous years. A growing interest in no-till and regenerative agriculture along with funding in the form of the FETF grants have certainly helped, whilst our continuous drive to improve, and build versatility into our machines has also been well received.
A busy build schedule throughout spring and summer was made slightly more challenging with the global supply chain crisis. As a British manufacturer, we’ve always endeavoured to use UK products and suppliers where possible and our close working relationship has helped to reduce the impact of any supply issues, ensuring all our delivery deadlines were kept.
Autumn brought the opportunity to get out onto farms to commission the new machines. It is always interesting to meet with new customers and discuss their plans to incorporate a new machine into their farming strategy. Our focus on producing versatile seed drills mean they will suit almost all strategies from inversion tillage to no tillage and all things in between.
It always interests me to hear what particular features of our equipment lead to our customers ‘taking the plunge’. Below is a list of some of the more common responses:
Many of this year’s new customers were looking to increase their output and had purchased drills with wider working widths than their outgoing machines. Pressure on farm labour, tighter drilling windows (delayed drilling for better weed control) and the lower horsepower requirement of our drills were the main drivers for going wider.
The Eco XL no till drill comes in widths of 8m – 13.5m and achieves a typical output of 6 – 10.5 ha/hr ensuring plenty of ground is covered in good conditions and when the opportunity arises. The low draught requirement of around 25hp/m mean that many new customers have been able to use existing tractors on our much wider drills, avoiding the need to replace the drilling tractor at the same time as the drill.
All the drills in our range use our forward facing, ‘J’ shaped tungsten carbide tipped tine. At just 12mm wide, not only does the tine avoid excessive mixing of the soil, but it also ‘pulls’ itself into work as it is drawn through the soil. This reduces the need for excessive weight to be applied to the coulter to gain penetration, as is the case with many of the disc direct drills on the market. Consequently, our Eco range of drills are around 50% lighter than many of their competitors, preventing soil compaction at drilling and allowing the drills to continue running in more adverse conditions.
This reduced weight per coulter requirement has been further exploited by fitting more coulters per meter of drill allowing for row spacings as tight as 12.5cm. This narrower row spacing providing users with a more competitive crop, preventing weed growth between the rows.
Dependable Depth Control
The Eco range of drills is fitted with Dale Drills’ independent drilling assemblies. Each drilling assembly includes a pair of tines, a depth setting press wheel and a hydraulic ram which lifts, lowers and pressurises the tine into work. Because each drilling assembly can move independently from all others, it is able to follow the contours more accurately, offering excellent depth control across the width of the drill. Placing every seed at an even and accurate depth, even on rough ground, ensuring uniform emergence and improving management of the crop throughout its growth cycle.
Many farmers have found this to be a huge benefit to their establishment routine, particularly in wetter drilling situations where excessive drilling depth can lead to smearing of the seed zone, and in drier situations where ensuring every seed is placed into moisture is critical for good establishment.
Low Draught, Low Running Cost
As previously mentioned, our drills are fitted with a 12mm wide Tungsten carbide point. These points tend to last c. 500ac per meter of drill (tines on a 6m drill would on average last 3000ac). Not only does this keep the cost of wearing metal to a minimum (c. £1.20/ac), but it also reduces down time and ensures output stays high, as there is not the need to regularly stop to replace wearing metal.
The low draught requirement combined with the low weight of our seed drills mean smaller, lower hp tractors (typically 150-180hp on a 6m) can be used. The lower initial purchase price of these smaller tractors helps to keep the standing cost low, whilst the greater versatility (the tractor could also be used on a fert. spreader, sprayer, corn cart, hedger, etc) ensure that the machine cost/hour is also kept to a minimum.
With increasing input costs across the board now, many farmers are looking for every opportunity to cut costs where they can. When these savings are combined with the financial and time savings from reduced tillage, the overall benefit is significant.
Meir SC – Low Disturbance Soil Conditioner
Dale Drills sister company, Meir Agriculture, has been established to provide a range of cultivators designed to fit within a Conservation Agriculture system. The Meir Soil Conditioner (SC) is designed to effectively relieve compaction down to approx. 12” without excessive soil disturbance at the surface.
The Meir SC is now available with an optional tine seeder mounted to the rear of the roller. In this configuration the Meir has been used to establish OSR & cover crops. Initial trials have shown the use of low disturbance tillage combined with cover crops has given yield benefits to following crops.
Dale Drills will be attending the LAMMA 2023 show at the NEC, Birmingham on the 10th & 11th January 2023. Come and see us to discuss our range of seed drills and cultivators in Hall 20 Stand 780.
Soil-Centred Worcestershire Sustainability Drive
Home-made compost, massively reduced tillage and determined cover cropping have been central to the single-minded drive to improve the arable sustainability of the Green Horizons Network farm at Salford Lodge, Pitchill just outside Evesham over the past decade.
A combination of challenging silty clay land contract-farmed with heavy kit for many years and lighter sandy gravel ground that continues to be rented out for field vegetable production, haven’t made the task any easier. And Tom Hughes’ effort to match both the productivity and low environmental impact of the substantial broiler business developed and run by his parents, Malcom and Liz remains very much ‘a work in progress’.
Even so, the improvements he and his Agrii agronomist, Kathryn Styan have made so far are obvious in huge reductions in blackgrass and brome problems, in far better structured and more resilient soils, and in the all-important bottom line – not to mention results from the first year of ADAS YEN Zero benchmarking.
Fresh from working on a progressive Wiltshire downland unit, Tom came back to the family business in 2013 to take the land in-hand. He recalls ‘jumping in at the deep end’ with the 120ha of heavy ground not in vegetable production full of enthusiasm for the no-till approach.
“With all the land rented out until then, we had no machinery at all,” he explains. “The ground had been demanding increasing amounts of horsepower to support deep-working and power-harrowing. Unsurprisingly too, given the poor soil conditions, black-grass counts were knocking on the door of 1500 heads/m2.
“This certainly focused the mind, and drew us to Agrii’s heavy land work at Stow Longa which has heavily influenced our thinking. We were tempted to do a reset with the plough. Instead, though, we decided on a winter of intensive multiple stale seedbeds followed by five years of no-till spring cropping. At the same time, we mole-ploughed the whole area to link-in with the drains my parents installed in the ‘eighties.
“After alternating spring wheats and linseeds followed by canary seed, our first crop of winter wheat in 2019 averaged 10.75t/ha with no black-grass in sight. OK, it was a good year for wheat, but this clearly proved the value of our soil-centred approach.”
In 2016, the vegetable ground was brought back into the rotation to address worryingly low organic matters and poor structure making the soils very prone to capping in the wet and baking hard in the dry.
Good quality land with irrigation is at a premium locally. So, it makes sound economic sense to keep renting it out. But field vegetable growing is hardly the most compatible with a
no-till approach. By cropping the ground themselves three years in every four and working closely with their vegetable-growing partners, the team has made sure their soil improvement efforts are not compromised by the land’s year in vegetables.
“They’ve been very receptive to this,” points out Tom. “We now have full overwinter cover ahead of every spring-sown crop, together with a programme of sustained annual organic matter addition.
“When we hand ground back for the vegetables – generally after a winter cereal – our partners spread certified green waste. We then establish the winter cover with a mix of species designed to suit their following crop on contract. At the same time, we are working closely with them to reduce their tillage in a number of ways.”
Integrating this land into the arable business instead of leaving it permanently rented out has added a further complication. Poultry litter from the family’s 10 broiler sheds has been important in improving the rest of the acreage, but this cannot be applied directly within the vegetable rotation.
To address this issue, Tom has developed his own simple but very effective composting operation. This involves mixing the litter with chopped straw from the farm’s 100ha of soft wheat – grown for the broiler rations – and grass silage from its 35ha of zero input grassland – which has to be removed annually under the Stewardship agreement.
“The grass silage adds extra green material which aids the composting process,” notes Kathryn Styan. “With a nicely balanced analysis, including 24kg N/tonne and good amounts of phosphate, potash, magnesium, calcium and sulphur, the 1000 tonnes made annually has proved a much better manure than pure poultry litter.
“It’s also just right for spring top dressing the winter wheat, overcoming the fundamental conflict between direct drilling and the requirement to incorporate organic manures. The active worm populations we now have in our soils naturally incorporated it in remarkably short order following application
“We’ve seen huge benefits from using the compost as widely as we can alongside our determined least cultivation, continuous green cover approach. Organic matter levels are up to 8% in places and all the soils both hold water and drain infinitely better. Ground we could seldom walk in the winter without getting covered in mud or sinking-in, now scarcely leaves a mark on our boots, or on the soil.
“Organic manures providing 20-35% of the nitrogen we apply to our wheat is a big financial win these days. What’s more, we only used 180kg/ha of N overall on wheat averaging 9.8t/ha last season – 40kg/ha less than the year before.
“Results from the six fields of winter oats, winter wheat and forage maize we entered into the initial year of YEN Zero last season as part of the Green Horizons initiative are also very encouraging,” she adds. “The yields Tom has been averaging for each crop are at the top end of the project results, whilst the greenhouse gas emissions remain some of the lowest. All crops scored especially well for emissions from the key areas of operations and synthetic nitrogen production and application.”
Operational emissions reflect the extent to which cultivations have been minimised at Salford Lodge. Central to this is the 4.8m trailed Weaving GD drill used for all arable and cover crop sowing, and chosen for the effectiveness of its angled double disc coulter system in cutting and closing the slot as well as the accuracy of its seed placement.
“Soil improvements are allowing us direct drill more crops more effectively every year,” says Tom. “Our ground is becoming much more resilient to both weather and machinery too. But we still need to relieve the panning which is inevitable in our high silty clay soils. We also have to eliminate the system of beds used for vegetable growing and incorporate substantial crop residues.”
“We have three bits of the cultivation kit which we use as sparingly as possible – all from our local friends at Weaving. We started off by retro-fitting their ultra-low disturbance legs to a Subdisc for deeper working but now rely far more on the LD Topsoiler at just 6”. After vegetables the light-weight Shortdisc is our first choice for tackling the residues left behind.”
While they accept some cultivation will remain inevitable at Salford Lodge for the foreseeable future, in no way does this lessen Tom and Kathryn’s enthusiasm for cover crops. From a simple combination of mustard, black oats and tillage radish, they are currently trying a twelve-way mix based on vetch, sunflower and black oats with four species of clover, fodder and tillage radish, buckwheat and phacelia on the heavy ground ahead of linseed, and on the light ground ahead of maize.
In addition to widening the diversity of rooting and biology, they see this as the best insurance against changing conditions, knowing that some elements of the mix will always establish well but they are likely to be different ones in different seasons.
“We match our covers very much to the time of sowing as well as the following crop,” Kathryn insists. “Early harvested vegetables give the best opportunity for them to work ahead of either autumn-sown cereals or maize in the spring so we tend to use more complex mixes here. Even after vegetable crops coming off as late as October, though, we think it’s important to get something in – generally something simpler and cheaper at a higher seed rate. This is more to protect the ground from rain impact than to do much good structurally.”
With the particular challenge of making the 70ha of maize they grow annually for a local AD plant more sustainable, the Salford Lodge team tried establishing a crop into a more permanent clover mix last season.
They set up the ground with the LD topsoiler, applied compost then matched the drill to the LD’s leg spacing with GPS and blocked-off coulters. Not having a precision drill, however, made for very uneven sowing, leading to much poorer yields than the 40t/ha they generally harvest. Serious weed problems which had to be sprayed off also meant the clover was lost.
Undeterred by this, Tom and Kathryn team remain both determined to maintain their pace of their sustainability improvement – especially as far as maize is concerned – and excited by the opportunities they see to do so.
Amongst their particularly positive experiences on the cereal side, they’ve been harnessing variable rate seeding to even-up field performance; using LiquiSafe liquid fertiliser treatment to eliminate at least one spring pass; better balancing crop nutrition to improve overall nutrient use efficiency; employing promising biologicals at T0 and T3 to reduce reliance on fungicides; and yield mapping and Gatekeeper to track their progress.
“We are putting lots of little things together within our broader soil-focussed approach to improve what we do in crop production alongside and as closely as we can with all the other environmental and carbon improvements being made by our broader family business,” concludes Tom. “Most obvious here are 15ha of short rotation willow coppice and a wood-chipping operation; 10 biomass boilers 23 air source heat pumps and a new ground source installation; and a 10ha array of solar panels.
“Having my brother George so heavily involved at the sharp end of a renewable energy and carbon sequestration business is a great help here, making what we are doing part of a truly integrated family-wide effort.”
Drill Manufacturers – Claydon Drills
Excellent soil health is fundamental for maximum farm productivity
With autumn drilling on the Claydon farm completed and crops developing well, Jeff Claydon, inventor of the Opti-Till® direct strip seeding system, discusses the importance of excellent soil health and the role of effective stubble management in achieving it.
30 November 2022
Excellent soil health is a prerequisite for maximum productivity on any farm. Soils in excellent condition will produce excellent yields and, conversely, those in poor shape will underperform.
The Claydon farm produced cracking yields this year, despite the driest spring/summer in decades and using up to 25% less nitrogen due to soaring prices and restricted availability. Our winter wheat averaged over 10t/ha, oilseed rape 4t/ha, and spring oats 6.11t/ha, so if your own results did not live up to expectations perhaps it is time to consider a different approach.
We operate on a commercial basis and earn our living by working in harmony with Mother Nature. Getting the best from the difficult-to-manage Hanslope series soils is a priority, so recent research data showing that reductions in tillage intensity benefit soil biology and health get my full attention. They confirm that the fundamental principles behind the Claydon Opti-Till® system, which we have used to establish crops since 2002, are correct.
One tell-tale sign of well-structured soils this year was that they did not crack deeply, unlike some I saw on other farms which were over-cultivated and had a dusty consistency, like dry cement powder. Where that was the case, the soil was bone hard when dry, so worms could no longer do their job, then after rain it went to mush and became unworkable. Inevitably, results were poor.
Soil health is a combination of its physical health, biological health, and chemical health, but what exactly do we mean by those terms?
- Biological health relates to soil biodiversity, feeding the soil regularly through plants and organic matter inputs, moving the soil only when you must and diversifying plants in both space and time.
- Physical health involves the texture and structure of the soil, the porosity and pore size distribution, water retention and transmission, together with aeration.
- Chemical health involves maintaining optimum pH, providing plant nutrients in the right amounts, in the right place, at the right time, as well as knowing your textures and mineral buffering capacity to optimally mine this supply of nutrients.
Once these things are right, we need the soil biology, which involves carrying out the right cultivations at the right time and having the right diversity of plants, which can encompass the use of cover crops.
A SYSTEM WITH BENEFITS
A German soil scientist who visited the Claydon farm described our Hanslope Series soil as ‘minute land’, namely that one minute it can be worked without too many issues using appropriate techniques, but the next it becomes unworkable, so timeliness is essential.
The other interesting fact brought to my attention on the Claydon stand at SIMA 2022 in the November was that a 1% increase in soil organic matter increases the amount of water available to the growing crop by 27,000 litres per hectare. That is a staggering amount, so when considering soil health appreciate that it embraces a wide range of factors, from drainage and water retention to worm counts, cultivations, and stubble management.
Claydon Opti-Till® originated in 2002 when wheat prices were under £60/t and for the farm to survive we had to reduce costs without adversely impacting output. Today, the cost of establishing crops using Opti-Till® is £59/ha, including stubble management with a Claydon Straw Harrow and seeding with a Claydon drill. This compares with £158/ha for a reduced tillage system and £195 for a plough-based approach. The economic advantages are significant.
As Opti-Till® has evolved many secondary benefits have become apparent. Time saving is considerable, allowing crops to be sown in the optimum drilling window and optimum conditions, promoting strong, even emergence. Major changes to the soil are also apparent where it is used, including a huge reduction in soil erosion. This coincides with a considerable increase in soil biota, soil is more stable, drainage is improved, difficult fields become easier to work, water holding properties increase, plant rooting is more prolific and its ability to cope with heavy axle loads is increased.
FOCUS ON FUNDAMENTALS
Good drainage is fundamental for excellent soil health. When this aspect is right you will never see standing water in fields, so that must be the starting point. After harvest, conditions were ideal for installing new drainage and luckily, we had 60mm of rain at the end of August, enabling us to mole areas that needed it, so we did that then cleared outfalls of obstructions and cleaned out ditches which had become overgrown or silted.
Free flowing outfalls and clear ditches are essential so surplus water can drain from fields.
The baking hot weather meant that conventional cultivations would have been very time consuming and expensive in terms of wear and tear on machinery, ground-engaging metal, and fuel. Instead, we used Claydon Opti-Till® stubble management techniques to move no more than 2cm of topsoil. The Straw Harrow achieved remarkable results very quickly, at minimal cost, enabling weeds and volunteers to be controlled mechanically so that only one full-rate application of glyphosate was required prior to drilling. This approach also helped to eliminate the ‘green bridge’ effect and reduce the aphid vectors of Barley Yellow Dwarf Virus (BYDV).
‘80-acre’ is one of our fields which I use as a reference point and have mentioned previously in Direct Driller. This season, we went in with the Straw Harrow immediately behind the combine, then carried out three further passes at seven to ten-day intervals. By mid-November, most stubble and crop residue had disappeared. This was due to the elevated level of worm activity, which was evident from the vast number of casts covering the surface.
Worm casts covered the surface of ‘80-acre’ field on the Claydon farm.
OPTIMISING SOIL HEALTH
A combination of structure and worm activity, good soil health is readily apparent. Soil in tip top condition smells fresh and breaks up easily when squeezed between the fingers. If it congeals and smells ‘off’ the right management techniques will be required to turn it around.
Worms play a key role in achieving this. These incredible creatures do a wonderful job, aerating the soil, allowing it to dissipate water in wet weather yet retain it in dry conditions. In combination with good drainage, they condition the soil and prevent it from slumping into a structureless, lifeless anaerobic mess, so we must do everything possible to encourage them.
Good times to check worm numbers are when the soil is damp in late autumn or early spring. Counting them is very easy using the AHDB guide (https://ahdb.org.uk/knowledge-library/how-to-count-earthworms) which also provides information on how to identify the various species. On the Claydon farm a respectable number in the spring is 20 to 50 worms in a 20cm x 20cm x 20cm AHDB sample plot, these figures highlighting the benefits of Opti-Till® over time.
In October, I had the pleasure of discussing our harvest results with fifty agricultural students from the University of Helsinki, Finland’s oldest and largest academic institution. They came to learn how direct strip seeding could enable farmers there to operate more efficiently and better utilise the extremely limited time window available for establishing autumn and spring-sown crops. Many came from the largest, most progressive farms in Finland which still use the same techniques as previous generations, but that is changing. Increasing economic pressures, more variable weather, and a greater emphasis on establishing crops in the autumn to increase yields, require a more timely, efficient, and cost-effective approach.
Our young visitors were quick to appreciate the benefits of Claydon Opti-Till® and the need for effective stubble management, a cornerstone of any efficient, sustainable, profitable crop production system regardless of where you farm, or which establishment method is used.
Worms only flourish where there is sufficient food and although that can come from many sources they thrive on straw, which must be managed correctly so that they can easily pull it into the ground and feed off the bacteria. That is difficult if the straw is too long, so it should be finely chopped – we aim for 5cm – and be on the ground. That is where the Claydon Straw Harrow comes into its own. On our own farm, this fast, low-cost process is used extensively as a part mechanical, part chemical approach. Where we must use glyphosate, we only do so under conditions which allow it to work most efficiently and apply a full rate to reduce the risk of resistance developing.
FAST AND EFFICIENT
Claydon began developing the Straw Harrow in 2007 and after extensive trials launched the first production version in 2010. Now a key part of the Opti-Till® System, it is available in 3m, 7.5m and 9m mounted versions, and as a 12.5m or 15m trailed unit.
All versions create a micro tilth in the top 30mm of soil, using the retained moisture to promote fast, even weed germination. They rake out and destroy weeds at the cotyledon and one‐leaf stage, removing a food source for slugs, break up slug nests and desiccate their eggs by mixing up and exposing damp chaff and straw to sunlight. In warmer climates this fast, efficient implement creates a mulch of crop residue over the soil surface, insulating it against evaporation, preserving valuable moisture and aiding seed germination, particularly for early sown cover crops and oilseed rape.
The first pass with the Straw Harrow immediately behind the combine is targeted at knocking chopped straw off the stubble onto the ground. At the same time, it creates a shallow micro tilth, 1cm to 2cm deep which prevents the ground from drying out and provides ideal conditions for weed seeds and volunteers to start growing quickly, within seven to 10 days if sufficient moisture is available.
Only cultivating the top 30 mm of soil eventually diminishes the seed bank, providing that seed return is kept to a minimum. Working at an angle and using the specially designed tines to move the soil across the working width of the Straw Harrow encourages volunteers, grass, and broadleaved weeds to germinate. Subsequent passes destroy the germinated growth without the need for chemicals.
Effective stubble management using Opti-Till® is the key to controlling weeds and volunteers and the extensive testing which we have conducted with the Straw Harrow highlights that the frequency of the following passes is crucial to controlling weed flushes with this method. Timing is key, so every time new shoots or growth appear another pass with the Straw Harrow should be carried out and subsequent flushes removed to ensure that the plants do not get too large and that the implement operates most effectively.
In a trial area on land that we took on this autumn the Straw Harrow was used twice. Weeds and volunteers developed strongly, producing a lot of green material that was too large to eliminate mechanically and had to be sprayed off. With red diesel now around £1.25 per litre, the cost of four passes with the Claydon Straw Harrow is less than one full-rate application of herbicide, so it is very cost effective and reduces the pressure on increasingly costly agrochemicals.
The exact nature of the stubble management process depends on the season. This year for example harvest was incredibly early, so we were able to carry out a first pass with the Straw Harrow in July and subsequently every 7 to 10 days until three or four weeks before drilling, at which point we sprayed off any remaining greenery. The biggest issue after harvest was that the land was so dry and hard weeds and volunteers did not germinate until rain fell. But had we used cultivations behind the combine seeds would have been buried, only to emerge with the growing crop, increasing reliance on pre-/post-emergence herbicides and costs.
WE’RE NOT PERFECT!
All autumn-sown crops on the Claydon farm were drilled with a 6m version of the new Claydon Evolution mounted drill behind our John Deere 8345. The output from this combination was such that after our oilseed rape had been drilled, we hired it to another farm, generating extra revenue. When it returned, we established all our winter wheat in six days, finishing on 11 October, by which time the combination had drilled our own one thousand acres plus a considerable area on contract.
While most of our crops are in excellent condition not everything has gone quite to plan, and lessons have been learned. Oilseed rape on the 40-acre field beside the access road to the Claydon factory looks a little patchy due to cabbage stem flea beetle and slug damage. The exceptionally dry summer weather forced slugs to go down deep into the soil to avoid dehydration and, when the weather turned wet, they returned to the surface ravenously hungry to feast on the emerging crop.
From that, we learned two things; without the use of the Straw Harrow, given the weather and with no application of slug pellets when drilling oilseed rape, the slugs find it as soon as it surfaces. We applied slug pellets immediately after it rained, but that was too late – we should have pre-empted the slugs’ appearance!
In the next issue I will track the progress of our crops and highlight the benefits which some customers are experiencing from using Claydon Opti-Till®.
The Claydon Straw Harrow is simple, robust, fast, and highly effective. Operating at 15 – 25km/h, its sprung steel tines pulverise chopped straw and crop residues, breaking it up for fast decomposition, uprooting weeds, and volunteers, as well as destroying slugs and their eggs. The operation is so fast and cheap that it can be repeated every 7 to 14 days when conditions are favourable. So little soil is moved that even if the weather does turn wet the fine micro-tilth it creates in the top 20-30mm of soil will quickly dry out allowing subsequent operations, either another pass with the Straw Harrow or drilling the next crop. The photograph above shows the first pass with the Straw Harrow on 80-acre field in July, immediately after combining. The one below shows the same field on 25 November, by which time worms had taken down nearly all the straw. The field will be drilled with spring oats.
Excellent soil health is hugely beneficial whether the season is wet or dry, says Jeff Claydon.
The Claydon Straw Harrow rakes out and destroys weeds and volunteers at the cotyledon and one‐leaf stage, removing a key food source for slugs.
Blackgrass emerging after the Straw Harrow has been used can be taken out with subsequent passes.
This photograph was taken on 11 October in a field which Jeff Claydon took on recently. For many years, the field had been min-tilled to a depth of about 150mm and was full of grassweeds which were difficult to deal with, so it received two passes with a Claydon Straw Harrow in early September. The first moved the chopped straw from the stubble onto the ground so that worms could easily draw it down into the soil, while a second encouraged seeds to germinate quickly. The field is destined for spring oats and will be sprayed off prior to drilling.
In this field on the Claydon farm the difference between two passes with the Straw Harrow (left) and four (right) is clearly visible, highlighting the benefits of carrying out as many as the weather allows.
This photograph, taken on 25 October, shows the effect of four passes with the Claydon Straw Harrow at seven to ten-day intervals, starting in July. Clearly, it has been very effectively controlled weeds and volunteers which would otherwise have emerged, while much of the straw has been taken down by worms. The field was sprayed off with herbicide at the end of October and will be left in this state until drilled with spring oats. Using the Opti-Till® system to manage stubbles helps to eliminate the ‘green bridge’ effect and reduce the potential for BYDV to develop. It also enables drilling to be delayed, but that means getting the crop in the ground quickly and not having too many operations before sowing.
Large numbers of birds on bare soil indicate a healthy worm population. This photograph was taken in a field on the Claydon farm after it had been drilled with winter wheat in October, then Straw Harrowed to firm the seed in prior to rolling.

Carbon farming is gaining ground … but not fast enough
Strategic Business Development Lead, Agreena
The opportunity for farmers to simultaneously capture carbon and improve their incomes is spreading in agricultural communities across the European continent and beyond. But a new report says the shift is “far too slow” and must speed up or risk “destroying the planet”.
Toby Simpson thinks more could be done to encourage regenerative farming adoption in the UK. “Farmers don’t receive enough support in making big transitions in their farming systems,” he laments. “There’s a lot of information out there, but it’s often hard to come by and to consolidate into a few places. There needs to be a lot more centralised support.”
Growing up on a farm in Northamptonshire, Toby is a graduate from the Royal Agriculture University and a current Nuffield Farming Scholar who farms in a regenerative way via cover crops and no-till planting. He has just finished travelling around Scandinavia, visiting like-minded farmers and seed breeders, to see how adaptable they are at establishing cover crops in a very short window of time due to inclement weather.
Their results have proved successful, but the takeaway is that the overall lack of awareness and education around regenerative farming isn’t an isolated issue. According to the study “Perception of Regenerative Agriculture in Poland”, commissioned by bank BNP Paribas and conducted by research firm Martin & Jacob, 38 percent of Polish farmers participating in the study did not know what regenerative agriculture is (although they were able to correctly associate it with environmental protection, improvement of soil properties and reduction of greenhouse gases).
“It is difficult to have widespread knowledge about regenerative agriculture, since there is a lack of sources of knowledge on the subject in Poland (…) Lack of information is a fundamental barrier to the uptake of regenerative practices,” admits Michal Siwek, Head of the International Food & Agri Hub Department at BNP Paribas.
A warming warning from a top task force
A recent report conducted by the Agribusiness Task Force, a network of global CEOs focused on climate issues and assembled under the Sustainable Markets Initiative, seems to echo the sentiments of both Toby and Michal. It claims that there needs to be more of a regenerative push and, unless something is done to immediately change the world’s agricultural practices, the planet runs the risk of ruin.
These words might sound draconian, but the lethargic pace of regenerative adoption has the world’s largest and most influential agribusiness companies and organisations worried enough to launch an action plan to scale regenerative farming globally in order to tackle the impacts of climate change and biodiversity loss.
“Regenerative farming is a critical part of the solution, and our report shows all too clearly that – despite pockets of great work – adoption rates are far too slow as the short-term economic case for change is not compelling enough for farmers,” says Task Force Chair and outgoing Mars CEO, Grant Reid. His outlook is shared by other task force members who act as CEOs for global conglomerates Bayer, HowGood, Indigo Agriculture, McCain Foods, McDonald’s, Mondelez, Olam, PepsiCo, Sustainable Food Trust, Waitrose & Partners and Yara International.
Their report goes on to state that the worldwide adoption pace must triple by 2030 to have any chance of keeping global warming under 1.5 degree Celsius. The 1.5 degree Celsius target is the goal of the Paris Agreement, which calls on countries to take concerted action to limit global warming by reducing greenhouse gas emissions. Scientists argue that if this temperature level is breached, it will unleash even more catastrophic climate change on the planet. “The 1.5 degree Celsius figure is not some random statistic”, warns World Meteorological Organization (WMO) Secretary-General, Petteri Taalas. It’s “rather an indicator of the point at which climate impacts will become increasingly harmful for people and indeed the entire planet.” And if that wasn’t enough to put adoption into action, the WMO goes on to claim that there is a fifty-fifty chance of the average global temperature reaching 1.5 degrees Celsius within the next five years, and the likelihood is increasing with time.
The Intergovernmental Panel on Climate Change (IPCC) has also recognised that carbon removals are critical to addressing climate change, reporting that greenhouse gas (GHG) emission reductions will not be enough to meet the 1.5 degree warming target. One billion metric tonnes of carbon will need to be removed annually by 2030 and five to ten billion metric tonnes annually by 2050. With <10,000 metric tonnes worth of CO2 removals thus far, the industry needs to scale and develop rapidly to avert catastrophic results1.
Scaling voluntary action carries enormous potential
With COP27 freshly in (but hopefully not disappearing) the rear-view mirror, the subject of catalysing growth in green businesses and innovation to initiate carbon removals and combat climate change was a hot topic on the agenda. And while agriculture has historically been singled out to blame for the climate crisis, accounting for approximately 20% of global GHG emissions, the sector is now seen as a windfall of opportunity to become part of the solution, with farmers acting as climate heroes for our future.
But transitioning away from conventional practices to more regenerative ones is easier said than done. That’s because farmers don’t know why they should change their production model in the first place, and they don’t know what benefits and losses they will have from doing so, although most seem to assume it involves some level of bureaucracy and are not interested in these solutions, regardless of the benefits they may incur.
The carbon market is changing that assumption, representing a new revenue stream for farmers who voluntarily join the green economy, with rewards that can be reaped annually. In fact, McKinsey & Company estimates that the market for carbon credits could be worth upward of $50B in 2030. And nature-based solutions, such as soil carbon, are estimated to account for 65-85% of the total credit supply.
“This is about opportunity, and it’s about playing offence,” says UN special envoy on climate action and finance Mark Carney. “It’s an industry getting together; because of what [leaders] are doing through their supply chain and business processes, [they’re] re-engineering and reorganising competitiveness. That’s fundamental. That’s offense.”
Scale with a little help from friends
Farmers simply cannot carry the burden of solving the climate crises alone. To scale the uptake of carbon removal practices, private entities, such as Science Based Targets and Greenhouse Gas Protocol, need to collaborate with public programmes and policymakers on local, regional and national levels in order to advance the climate-smart agriculture agenda and move the industry forward to net zero. This means clarity across the board when it comes to scaling carbon removals, including:
- Wider recognition for the carbon certificates generated in the agricultural sector
- Standard setter being more open to agriculture-based projects
- More clarity across the relationship between countries’ Nationally Determined Contributions (NDCs) and carbon-related projects
- A healthy relationship between the supply-chain / carbon neutrality process – avoidance of double counting
Scaling green carbon initiatives and technology holds enormous promise for a net-zero transition. Interestingly, global carbon projects financed by the voluntary private sector have already reduced over 450M tonnes of CO2e, which demonstrates tremendous potential. But it will require more massive leaps in progression to “hyperscale” climate technology innovation to the level needed to comply with targets. In fact, McKinsey partner Anna Granskog has suggested the need for 200 to 300 green decacorns (unicorn companies worth at least $10 billion) by 2030 to meet climate targets.
“You need partners, you need friends,” admits Anna during a COP27 panel discussion on scaling new green businesses. “There’s no silver bullet. We need huge amounts of deployments toward all technology.”

Farmer Focus – Simon Cowell
After the summer’s hot, dry and easy harvest, my drilling season proved to be somewhat frustrating. Soils were baked hard and cracked right through until the middle of October, small bits of 3 to 5 millimetres of rain dried within twenty-four hours meaning that even if I could get seed into the ground, it would have had to sit and wait for considerable rain to trigger germination. By about the fifteenth of October, land after winter beans and lucerne were just moist enough down to about an inch and so I was able to drill into this shallow layer with the Sim-tech. Pre-em herbicides and Avadex went on the day after and have done a brilliant job of stopping blackgrass emerging with the wheat. Unfortunately, wheat stubbles and land after linseed were so cracked to depth, and with my high magnesium levels setting the surface like concrete, there was no way they could be drilled. Of course, then the weather turned and it was then a case of trying to find a couple of consecutive dry days to do any more drilling. I did manage to get some winter barley into some wheat stubbles around the tenth of November, and although it was sort of “kicking mud of your welly boots getting back in the cab” conditions, it has now come well, albeit with a little blackgrass for company. I still haven’t drilled the ex-linseed ground and don’t think there is much chance now. This is proving to be a bit of a flaw in my system. Linseed is a fantastic crop for me, I always get the best wheat yields afterwards and it leaves the soil in perfect condition. It doesn’t need to be drilled too early in the Spring allowing time for the soil to dry and because I have a Stripper Header, it is quick and easy to harvest. The only problem is that for the following crop, I have to use my Moore Uni-drill to get through the standing linseed, the tined Sim-tech bungs up within a few yards. Whereas the Sim-tech will go in wet or dry conditions, the Moore is much fussy, too dry and it just rolls along on top, too wet and it smears the slots and just make a mess. Unless the weather co-operates, I can end up not getting a crop in, which has happened once or twice before.
Like several other longer term no-tillers I have spoken to, my headlands are yielding more than the rest of the field. When this started to show a few years ago, I thought that maybe there was some sort of benefit from natural biology encroaching from the hedges and trees around the outside. It is now obvious though, that from the sharp drop off in parallel lines around the headlands, the effect is directly related to where I am turning with drilling, harrowing and rolling operations; the outside of the field is being compressed twice or three times as much as the centre of the fields. All my field operations are done at different angles, straw raking at 45 degrees, drilling 15 degrees from the previous year, post drilling harrowing and/or rolling at up to 90 degrees; this means that every headland is a turning headland so the effect goes right round every field. I now think that the headlands are how things should be and that there is something going wrong with the rest. It appears that this no-till soil is becoming too loose, too free draining and too aerobic. It seems to me that the physical is affecting the biological, and therefore there is a difference in the chemical (nutrient availability).
Back in the summer I decided to do some investigations, taking soil and tissue samples from obviously good headlands and out in the main parts of fields of wheat and beans. I now have Olson, Albrecht, La Motte and Total test results, tissue analysis, mycorrhizal colonisation and comprehensive soil biology analysis. There is a marked difference in Phosphate availability on the Olson tests but all the other soil tests show the same levels across all samples. Mycorrhizae are no different, but there are some big differences in fungal:bacteria ratios and the numbers of some protozoa are vastly different. I am starting to build a picture of what is going on and will be doing more complex biology tests when the soil warms up in the spring. I would like to thank Robert Plumb of Soil Fertility Services for his help in organising the testing, sending samples to many different laboratories across the country. Robert recognised the importance of finding out what is going on in the soil, and whether it had implications to the general idea as to whether we should be striving for more aerobic and fungal dominated soils.
Drills in Focus – Vaderstad
Written by Mark Hatton
When you get asked by one of the world’s biggest machinery manufacturers to attend the press launch of its new drill, it’s pretty difficult to say no!
On a recent trip to Germany, with Vaderstad UK, I had the opportunity to find out much more about the company, its history and a little insight into their future plans.
60 years of agricultural machinery innovation is quite some achievement.
From its origins in Sweden to its now global market, Vaderstad has been manufacturing tillage and sowing equipment since 1962.
Now in its third generation of family ownership, headed up by its president and CEO Henrick Gilstring since February 2022, the company’s 13 shareholders are all very much part of the family.
With its roots still very firmly in Sweden, Vaderstad is now represented in over 40 countries worldwide, employs over 2000 people, manufactures over 7000 machines and over 1,000,000 genuine wear parts annually.
2022 has seen an overall growth of 25% on the previous year, with new markets, such as North America expanding by over 40% with acquisitions of brands such as Wil-Rich, Concorde and Wishek.
Vaderstad is truly a global brand.
The company has, in many ways, led the industry in terms of technology and innovation.
Since its first rigid tine harrow in 1962, right through to present day and the new Proceed Drill, the brand has been synonymous with machines such as the Rapid, Carrier, Topdown and Tempo.
Its four worldwide research and development sites continue to combine agronomic science and trends with technological development, producing machines that will aid farmers around the world combat the challenges of a growing population, climate change, sustainability and rising input costs.
Complementing the R&D sites is the new Vaderstad Farm Germany, a purpose built facility for training, networking and farming trials.

The farm offers a one stop facility, that allows Vaderstad to share its knowledge with its employees, external partners and farmers alike,

This includes field trials with external partners, such as Sygenta, allows for knowledge exchange, such as transition from a wheat dominated to a multi-crop rotation new crop trials and Cover Crops permanently integrated in-crop rotation allow for machine demo plots throughout the whole year.
One of the Vaderstad Farm’s design features is its viewing area, perfect for showcasing the company’s machinery.

One of the best known and most successful Vaderstad machines has been the Carrier disc cultivator range, mounted or trailed from 3-12m widths, with multiple options of discs and packers.
The latest innovation to the Vaderstad disc range is the Crosscutter disc Aggressive, designed to give better penetration in hard, challenging field conditions, a further benefit of the CrossCutter Disc Aggressive is that it will act more aggressively in heavy residues such as silage maize, heavy oilseed rape stalks, or sunflower stubble, aiding the breakdown of large volumes of material.

The latest revolution in planting technology from Vaderstad is the new Proceed. The challenge, accurate seed placement, accurate seed depth, by reducing seed rates at planting while not affecting overall yield at harvest, impossible?
Proceed is a whole new category of seeding machinery. With an unmatched level of precision, it works with full capacity to fit every farmer’s needs. This one machine can increase the yield potential of a full range of crops, such as cereals, oilseed rape, sugar beet, peas, maize and more. Proceed simply offers more than any previous seeding machine, making farmers ready for a fast changing future.
The first thing you notice is the size of the seed hopper, or lack of it!
With the overall goal of using lower seed rates, the requirement for huge hopper capacity isn’t needed, this in turn reduces overall machine weight, which ultimately benefits the soil structure and a reduction in fuel usage.
Pic 9 (Proceed2)
At the core of the innovation that Proceed brings is the unique ability to treat every seed individually and place it at exact millimeter depth. An innovation making a huge agronomic impact. Based on a wide number of field trials, you can expect improved health and size of crop, higher germination rates, quicker emergence and an even crop population. Increased precision enables a reduction of seed rate and an optimization of plant protection and treatments throughout the crop year.
Expected to be available to purchase later in 2023, the results so far have been very encouraging.
If the last 60 years is anything to go by, the future of Vaderstad looks to be in safe hands.
De-risking OSR establishment
Farmers are reporting positive benefits of drilling primed seed
Despite 37 years’ industry experience, Agrii agronomist David Vine readily admits that growing oilseed rape successfully year-in, year-out can still be a huge gamble for many growers with significant challenges posed by slugs, pigeons, cabbage stem flea beetle (CSFB) and, given this year’s weather, the often-difficult task of finding adequate soil moisture.
David says: “It’s still a lottery and, over the last 37 years, I’d argue that it has become even more difficult, with serious blackgrass resistance and the neonicotinoid ban to add to that list of challenges.
“However, there are new ways in which rape growers can stack the odds in their favour. The advent of priming technology into oilseed rape in the last two years has made a difference. It’s a proven technology that increases early plant vigour, offers more even crop germination and, given that there are no chemicals involved, it’s a sustainable and environmentally friendly process” he adds.
Working with farming business A & E Beckett, based near Birmingham, David recommended a trial on 21ha of primed Tennyson, the only primed hybrid OSR variety available in the UK. Direct drilled for minimum soil disturbance on August 12th, at a rate of 50 seeds per M2 along with two unprimed varieties, David confirms that the early results have been extremely promising.
“We drilled the primed Tennyson in fields that had been left fallow for one year, but despite this unusual scenario, combined with only 30mm of rain in the first 3 weeks post-drilling, the crop came through with great uniformity and continued to grow well despite the combined attention of CSFB and significant pigeon populations. By the 3-4 leaf stage the Tennyson still looked healthy with only small shot-holing on the leaves from the CSFB grazing.
“Unfortunately, the two unprimed varieties suffered heavy attacks from flea beetle on August 24th and 25th and we were forced to spray some growth stimulants to help them. However, the primed Tennyson crop didn’t require a spray due to its advanced early growth stage.
Beyond the priming technology, Tennyson is an impressively resilient variety with a strong disease profile. Its verticillium resistance trait could also be a major positive on farms with tight rotations and I will be following its progress closely” he concludes.
Based on the Lambourn Downs, between Wantage and Lambourn in Oxfordshire, farm manager Piers Cowling of Sparsholt Manor Farms direct drilled 62ha of primed Tennyson at 40 seeds per M2 on Sept 3rd, having achieved 3.45t/ha on a 50ha crop of unprimed Tennyson earlier this year.
Piers says: “With no rain in August we were forced to drill later this time, although there was a lot of confidence behind Tennyson, given we knew it had displayed significant early vigour last year.
“Of the rape varieties we selected, Tennyson was the last to be drilled but – despite the staggered starts, all 3 varieties emerged together during the week commencing September 11th, with the Tennyson crop the most uniform of the 3. With the benefit of some much-needed October rain all our rape is progressing well, successfully overcoming some CSFB grazing at the expanded cotyledon stage” concludes Piers.
Farmer Peter Legge of Legge Farms Limited, based on the Norfolk-Cambridgeshire border, has been growing OSR for the last 15 years across soil types ranging from heavy clay to sharp sands and organic black fen. Working with Simon Hobbs of Agrii, Peter direct drilled 50ha of primed Tennyson on August 25th-26th, later than planned due to the prolonged dry spell.
Peter says: “The first month is always critical, and you have to give the young rape crop every advantage available during the first 4-5 weeks of its existence to try to ensure good germination and rapid growth away from pest activity. We’ve been working closely with Simon Hobbs for over 15 years now and, having seen Agrii’s trial results on primed OSR seed, it was a no-brainer to trial a primed variety.
“The early visual signs were very positive with the crop showing very even emergence 6 days post-drilling. During the second week of September, we did see some CSFB grazing activity, but we were quick to react, adding an insecticide to our post-emergence herbicide tank mix that kept the crop on course, with only low-level shot-holing noted in most of the young OSR plants.
“I think we were more confident this time with primed Tennyson, evidenced by our decisiveness with the herbicide spray. In other years, following a flea beetle attack, we’d have occasionally held back on applying further inputs until we’d properly accessed levels of crop damage. As of late October, 9 weeks post drilling, the Tennyson crop was at the 10-12 leaf stage with a healthy, dense canopy that tends to stop pigeons from settling in the crop as an additional positive” concludes Peter.
Farmer Focus – Ben Martin
Well, the last few weeks have been exciting! A few weeks back I finished a 7yr stint managing a large veg and cereal operation in West Suffolk and am now taking a bit of time off to explore what direction I want to take myself and my little family next. Taking a bit of time out has come at a great time for me personally, we have come through yet another season of intense pressure to get crops to harvest (thanks mainly to that wonderful draught we had) and I need this time to decompress, to see what is out there (potentially outside that farm management bubble) and to start the new year in a rejuvenated mindset. Oh, and I turn 40yrs old shortly – talk about a midlife re-evaluation!!
So, how did I arrive at this point? Before I come to that, a quick intro. I’m Ben, I live in a glorious part of West Suffolk, with my amazingly supportive wife Emma, our beautiful little girl Maeve and our spaniels. I love spending as much time with them all as possible, but I enjoy my own company as well – out walking and exploring, cooking and watching the mighty Ipswich Town Football Club.
Farming is all I have ever known really, I don’t come from a farming family as such, but Dad and Grandad worked for the local farmer for most of their careers. We lived in a tied farm cottage on one of the farms, it was just the best environment to grow up in. We were lucky enough to been bought up around plenty of animals, sheep, pigs, chickens, and goats were all family pets during our childhoods. My teenage summers were spent working for a neighbouring farming family, they gave me the most wonderful start to farming and instilled into me early on, how to work hard, attention to detail and how to look after people (the best harvest teas ever!!).
An Agricultural degree from Writtle College came next and like most old Agri students will say, that was the best 3 years ever! Learning a lot, socialising A LOT and making the best friends. Friends that are still very much part of my life 20yrs later. I spent the rest of my twenties gaining so much real-life experience of farms. Working on remote sheep farms in the darkest depths of mid Wales, silage seasons in Yorkshire and big arable farms in East Anglia. I loved them seasoning rolls, traveling around and meeting some great people.
The backend of my twenties I met my now wife Emma, another Young Farmers success story! During that time I was really enjoying things, as everyone should in their late 20s. I was working with a really kind and supportive farmer, where I was able to use spare bits of his farm to establish a firewood business and rear rare breed pigs in his woodlands. It was a great time, hard work but so rewarding. I was also lucky enough to secure a 6yr FBT of my own, on 32ha of arable land, what an eye opener that was – growing and financing my own crops. An experience not many farm managers can say they have had and one that I learnt so much from. It was during this time that I had my first real exposure to cover crops and direct drilling. I established a basic mustard cover crop on my land in front of potatoes and using a Claydon Drill with the chap I was working for.
In my 30th year, after much saving, my wife and I had a once in a lifetime trip to New Zealand. We travelled the South Island in a camper and had the time of our lives. With no real time pressures etc, we just plotted a big loop around the Island and spent the next 4 weeks in our camper cruising around exploring the amazing South Island. An unbelievable experience, as everyone says who has been to NZ, but also an experience where I had time to reflect on things and concluded that as much as I had enjoyed my late 20s, I wasn’t going to have the structure or security by carrying on, to support a family in the future. So, when we got back, I had a final year doing what I had been before we went and then decided to try and carve out a career in farm management.
The next 7yrs was spent as assistant, then manager, on a 1300ha veg and cereal business. A massive opportunity and one where I learnt a huge amount. A complex operation, with high value crops, irrigation, several full-time staff, draught prone light sandy soils and working with various landowners. During my time there I had support and a real driving passion to try my hardest to repair and improve the soils on the farms involved, without removing the veg crops from the rotation. Not an easy task – but one that I was not alone in tackling. Taking things cautiously and steady, I started with 10ha of over winter cover crops in my first year to cover cropping all land in front of spring crops in my last couple of seasons (400ha) and integrating livestock into the system by having sheep on farm to over winter on these cover crops. The farm staff bought into my vision, that was very important. Cover crops were a vital tool to helping the soils improve, as was working the light soils a lot less and only cultivating deep where absolutely necessary. Companion crops were grown alongside OSR crops, catch crops between early lifted veg and following cereal crops and a 4ha regenerative potato trial grown alongside a very supportive processor. Introducing a 1 pass drilling system, using a new low disturbance subsoiler tool bar and the existing drill (Horsch Pronto) hooked on the back, was a real success. Financially, there was a huge reduction in establishment costs but also a much-improved timeliness of the operation as it cut out 2 cultivation passes.
I was fortunate in being able to bring inspiring and highly experienced people on the farm, such as Ian Robert and Ben Taylor Davis, to help us along with what we were trying to do. Getting the whole team around a soil pit on the farm, with Ian stood in the bottom of it was one of the best spent days we all had as a collective!
However, things move on and as a lot of people have told me recently – a change is as good as a rest!
So, what now…?
This is where it gets exciting!
Since posting on Twitter that I was moving on and looking into future opportunities, I have had several conversations with people about future roles and direction. Areas of agriculture I hadn’t really considered historically but ones that now look attractive. I am approaching all of this with a very open mind – you have too, that farm management bubble I had been in for several years does seem to prevent you at times to see the bigger, industry wide picture.
I am focused on an environmentally sensitive farming approach; I would certainly be keen to stay in farm management and work with a landowner who is of a similar mindset. I have known great people like Adam Driver and John Pawsey for along time now, they are good friends, I have worked for them both and in my opinion, they epitomise how large farms can work closer with the environment, albeit using 2 differing approaches to farming their land.
My short-term aim is to get out and about, meeting and chatting with as many people around the UK as possible. People that will lend me an hour or 2 of their time, just to chat and have a wonder around their businesses maybe. Not just chatting farming, but life, business and general stuff too. I have got recruiters lined up to chat with, companies to chat with who have approached me, but I want to speak with individuals as well.
As I said earlier, I am open to all discussions going forward. I know I have a lot to offer, its just finding that opportunity that fits right for me and my family going forward. Please do drop me a message if you would like to have a natter and have an hour spare! So, for now, I am going to enjoy some quality time off with my beautiful girls. And some long dog walks!

No-Till, Cattle & Diverse Cover Crops Mix Well
Written By Sarah Hill and originally published by No-Till Farmer in the USA
The combination of a 3-way crop rotation, covers and grazing is resulting in big savings by reducing the number of tillage passes, increasing yields and improving soil health.
Pictured Above: SHORT GROWING SEASON. No-tiller Kurt Stiefvater has a very short fall season to get cover crops planted, and the weather plays heavily into his selection of which cover crop species for a mix.
In farming, it’s the little things that will get you — or add up to more profits if they’re done right.
Salem, South Dakota, farmer Kurt Stiefvater, knows something about that. He started no-tilling 20 years ago to save soil moisture and save more money by reducing the number of tillage passes.
He added small grains and cover crops to the 1,800-acre operation 8 years ago, and those decisions have improved Kurt’s yields, soil health and the condition of his cattle herd.
No Hard Formula.
Kurt has a very short fall season to get cover crops planted, and the weather plays heavily into his selection of which cover crop species for a mix. If a field has more alkali spots, he’ll add barley. He tends to be careful with brassicas and doesn’t use buckwheat much as he doesn’t feel it’s very easy to control.
His 8-10 species cover crop mix typically includes 10 pounds of oats; 12 pounds of winter wheat; 2 pounds of sorghum; 15 pounds of soybeans; 1 pound of red clover; 2 pounds of sunflowers; ½ pound of flax; ½ pound of turnip; and ½ pound of radish. He might also throw in rye, legumes, millet or common vetch.
In addition to the weather, Kurt looks at the different characteristics of each cover crop species when choosing which ones to use in his mixes, as well as what his 130 pairs of Black and Red Angus cattle will graze. He uses an oil variety of sunflowers because even though the seeds aren’t viable, the cows love to eat them.
“That’s why I tend to use more small grains and sorghum in my cover crop mixes,” he says.
MILLION SEEDS PER ACRE. Oats are part of Kurt Stiefvater’s 3-way rotation, planted around April 1. He plants 80-85 pounds per acre of oats with a goal of seeding 1 million seeds per acre.
Most of his cover crops either winterkill or are grazed, but for any cereal rye or winter wheat that survive, he uses a pre-emergence herbicide application to terminate them.
“We’ve had more problems with winter annuals, dandelion, etc.,” he says. “I add a little 2,4-D to knock it back.”
He adds that using cover crops has allowed him to cut his rates of nitrogen (N), phosphorus (P) and potassium (K) by about 20% each. Kurt only uses 0.8 pounds of N per bushel of yield goal now, compared to the 1.2 pounds per bushel of yield goal that he used to use, without yield loss. He has added some sulphur and boron to his fertilizer plan, too.
Waiting Game. He uses a 3-way rotation of corn, soybeans and oats, but he has to wait sometimes for the right conditions to plant, compared to his neighbours.
Oats are planted around April 1. Corn planting starts around April 20-25 with beans following that.
Kurt plants 80-85 pounds per acre of oats with a goal of seeding 1 million seeds per acre. He plants with a Case IH SDX with a 2330 air cart at 7½-inch spacing.
He seeds 32,000 seeds per acre of corn using a Case IH 1245 drill with Yetter SharkTooth row cleaners out in front to clear away extra residue. A Case IH MX 255 pulls the planter and the drill.
“We’ve used untreated corn before with no problems,” says Kurt. “It’s hard to order corn seed without a seed treatment, so then we’re stuck with that variety. We tried planting some corn with the air drill and had fair success with it. We’re trying to figure that out because it needs to be more accurate.”
Soybeans are seeded at 120,000 seeds per acre. He’s transitioning to using an air drill for planting all crops.
“We were using 38-inch rows in the late ‘90s,” he says. “We bought a planter with a splitter attachment so we could go down to 19-inch rows of corn.”
The narrower rows on the 100% no-tilled ground created a canopy quicker in the corn, blocking weeds and saving moisture because the sun wasn’t beating on the soil.
“As we upgraded equipment, we stuck with 22-inch rows,” Kurt explains.
Kurt says he applies a 6-24-6 fertilizer starter and broadcasts a light rate of P, K and N as a dry fertilizer before planting.
“I apply half of the N before planting, then come back at the end of June and sidedress with 28% urea using drop nozzles on my AGCO 854 Rogator sprayer,” he says. “Dry fertilizer is put on soybeans, but it’s spread out over 2 years.”
Kurt applies enough P and K to the corn that the soybeans have some for the following year. He applies 25 pounds of N, 35 pounds of P and 45 pounds of K to soybeans; 70 pounds of N, 45 pounds of P and 45 pounds of K to oats; and 0.8 pounds of N for corn. Soybeans are inoculated with a bacterium.
When his corn and bean yields plateaued, Kurt says he had to figure out a way to make more P and K available in the soil.
“We achieved that goal by working more nutrients in the rotation and adding more crops, like oats, to our rotation,” he says.
“Adding winter wheat to the rotation was an experiment…” – Kurt Stiefvater
Oats are harvested the first week of August, and covers are planted after that.
“We yield 100-130 bushels per acre with oats, which is 10-15 bushels better than the historical average in our area,” he says. “If it really grows well, and we have a good year, I can sell part of the oat straw for extra income.”
Corn and soybeans are usually harvested mid-October through November using a Case IH 7120 combine. Kurt has a Case IH draper head for soybean harvest and a Capello corn head for corn harvest. Corn yields have been in the 190 bushels per acre range, and Kurt goal is 200 bushels per acre (13.5 tons per hectare). On average, soybean yields have been 50-55 bushels per acre (Approx 3.4 tons per hectare).
Kurt says he experimented with planting flax and oats with a Case IH planter, switching the discs on it for more uniform planting depth.
“We planted 22-inch rows, coming back and offsetting 11 inches for the oats,” he says. “We got good emergence, and we used a lot less seed and had more accurate planting.
“Adding winter wheat to the rotation was an experiment,” Kurt says. “It was food grade wheat, hardy enough to meet the necessary specifications for the food market.”
More Days, More Grass.
Kurt says he wants covers in his program that will provide enough growth to be used for winter feed for his cattle in their rotational grazing program.
Kurt manages 600 acres of pasture, renting three-quarters of that acreage from family members and neighbours. He has 9 paddocks where cow/calf pairs graze and utilizes conservation stewardship programs through NRCS.
He has pasture taps or water lines centred in each pasture that makes a pie shape away from the tank for a water source. He uses electric fence to divide up the pasture into equal acres and rotates the cattle so they still have access to water.
Since switching calving from March/April to mid-May and June, he says that mother cows are milking better on the larger amounts of grass available.
“The cows also get more water in their diet, compared to eating dry hay,” Kurt says. “That’s helped with calving problems.”
Calves are healthier at birth because cows aren’t experiencing their last trimester during the coldest part of winter. And since they’re not fighting the weather, the cows don’t need such a high requirement diet for a stressful season. He keeps pairs in groups of 10-20, and they’re out on pasture until the grass gets short. In November, he moves them to a cover crop field.
The cattle have seemed to really like the diversity of the cover crops, according to Kurt.
“They eat more, and it’s easier on the cows,” he says. “Calves get a variety to eat, and I can tell they’re gaining. The cows have better body condition scores. I keep salt and mineral in front of cattle year-round so they get a better balance of nutrition. When the cattle are grazing cover crops, they hardly use any of it.”
Calves are weaned the first week of December and sold the first week of March.
Kurt notes that the fall was dry in 2020, so the covers didn’t grow much. But most years, grazing cover crops cuts his hay usage by 40%.
Tracking Soil Organic Matter. The farm’s soil organic matter was going down before they switched to no-till, Kurt says. He began doing soil testing every 3 years after soybean harvest to track organic matter levels.
“When we first started no-tilling, we were getting a 2-2.5%,” he says. “We’ve seen some fields increase to above 4%.”
COWS’ PREFERENCE. Because Kurt Stiefvater grazes his covers, he includes more small grains and sorghum in cover crop mixes. He uses an oil variety of sunflowers because even though the seeds aren’t viable, the cows love to eat them.
Kurt has a wide variety of soils, from gravel to heavier loam to sand and even higher clay content. Their soil has 6-10 inches of black soil and then turns to clay, so water tends to be held toward the surface.
To boost soil health, Kurt likes to incorporate legumes and sunflowers in his cover crop mixes for their taproots that burrow down into the soil.
“I try to have lots of living roots to keep the soil active as long as I can, even after a freeze,” he says.
The cover crops provide protection to the soil throughout the winter, resulting in less blowing soil and erosion from the wind and water. An extra benefit for Kurt is the wildlife like deer, pheasant and partridge flock to the covers as a food source.
“We’re still in transition phase,” he says. “We keep learning more about how different plants interact with the soil and how to manage that. We’re trying to maximize the soil and keep a living root as many days out of the year that we can and incorporating livestock. I really like the soil biology component that cattle traffic stimulation does to the soil, the way the cattle cycle nutrients and spread them across the field.”
Kurt says that the soil biology helps his cash crops take off once the plants get rooted.
“I really like having mycorrhizae in the soil, since they help plants capture the nutrients and water in the soil,” he says. “The soil biology needs oxygen, too.”
Kurt has seen improvements in the water-holding capacity of his soil. He gives the example of a dry spell in 2020.
“Having that protection with residue and more earthworms and other insects digging around in the soil really helped,” he says. “I like to get out and sidedress fertiliser or spray right after a rain, but I don’t have to worry about getting stuck. The soil can hold the equipment better on wetter soil.”
The improvements he’s seen to his soils go beyond the top layer. Kurt says he’s dug soil pits and used a shovel to evaluate his soil and he’s been impressed with the results, as roots are expanding better and there are more places for the roots to grow through earthworm holes.
The South Dakota Soybean Association conducted nematode tests on his property and found that they were way down. Kurt seeks to keep improving his soil by increasing organic matter and cutting down on erosion, while not using any insecticides or fungicides.
“When things are all in balance, you shouldn’t have any rootworms or an imbalance of nematodes to treat,” he says. “We don’t use insecticide or fungicide because they might disrupt what’s going on in the soil. Insecticides and fungicides don’t just kill the bad stuff — they kill the good bugs, too.”
Savings That Add Up.
Kurt says he’s looking for ways to change things up to save money and time. One example of that is selling seed oats, which he says are relatively cheap. He has saved $100-110 per cow per year on extra feed costs.
“If we get hailed out or if it’s too dry and we can’t harvest the oats for grain, we can use them as a winter back up feed source for the cattle to graze or even harvest it by putting it in big round bales,” he says. “It’s a versatile crop. Barley is the same.”
Switching to no-till has already saved Kurt a bundle. He says that cutting just one tillage pass has saved $15-20 per acre.
