Telling the story of farming, climate and nature in Cornwall

Food systems under threat from climate change

Among the many threats posed by climate change, maybe the greatest is to our food systems. With our country producing less than 60% of what we eat, and the climate crisis already having a huge impact on many of the places we import our food from, the UK clearly needs to become more self-sufficient.

But increasingly extreme weather is affecting food production right here too. Following last winter’s endless rains, British farmers have had one of their worst harvests ever. We know that the way our land is farmed and managed can help us to mitigate the impacts of the climate crisis… or indeed to make things much worse.

However, with farmers facing unprecedented financial challenges and record numbers now fearing they’ll go out of business, can we realistically expect them to protect us all from climate change too?

Farming and land use are also increasingly becoming a lightning rod in the climate culture wars. Half-truths, misinformation and outright lies are being pushed across social media by those with a vested interest in crushing the whole green agenda.

While filming the Cornwall’s Climate Stories documentaries, we’ve been keen to find out whether all of this is impacting real world efforts to boost pro-climate and nature-friendly farming.

Farmers centre stage, with a supporting role by FCT!

As filmmakers without a personal connection to farming, it’s been fascinating for us to interview so many farmers and food producers across Cornwall (and our film Food for Thought was actually presented by an organic beef farmer). 

We’ve also featured several members of the Farm Carbon Toolkit (FCT) team, including technical director Becky Willson, who we met in the middle of the 2022 drought.

Becky took us out in a Cornish field to show us the huge differences that regenerative farming can make to both farmers and wider society. Biologically-healthy soils are not only more fertile, but also store more carbon, support more wildlife, and hold much more water – reducing flash flooding during our increasingly torrential downpours, but also enabling crops to keep growing during increasing periods of drought.

Another of our interviewees was FCT Impact Manager Jonathan Smith, who is trying to adapt to increasing coastal erosion as the sea level rises around his beautiful organic farm on St Martin’s in the Isles of Scilly.  

Meanwhile, Farm Carbon & Soil Advisor Anthony Ellis appeared in our film Power to the People about climate change and energy, addressing one of the biggest flashpoints around climate action in rural areas – solar farms.

The loud public outcry against the idea of solar panels covering productive farmland has been unavoidable. However, Anthony believes we’re missing a trick by viewing land use in such a binary way. 

He has raised his panels up 18 inches higher than usual to allow his sheep to graze beneath them. Aside from bringing him in additional income, the panels also improve the welfare of his animals.

When we visited on a very hot summer’s day, the sheep were relaxing in the shade of the panels and Anthony explained the grass holds on better beneath them during droughts than it does out in the open. Chickens can be kept beneath solar panels and all manner of veg grown between them too. 

Anthony’s sheep under solar panels on a warm day

Few will argue that solar farms are beautiful – but the popular view of these sites as sterile and lifeless can be far from the truth. Recent studies have found well-managed solar farms act as vital havens for wildflowers and critical pollinators among barren landscapes of industrial farmland.

Bringing nuance into the debate

Concern over food security is totally understandable. However, even if all the solar area envisioned in the government’s net zero plans were built, this would still take up only 0.3% of our land area – just half the amount of land taken up by golf courses (and 0.5% of the land currently used for farming).

Solar farms are far from the only controversial way of using farmland to tackle the climate crisis though. Tree-planting initiatives are also leading to fears of food-growing areas being lost. 

However, the picture is more nuanced here too. Agroforestry is a great way of introducing more trees into the landscape, while still using it for farming.

Chris Jones, who farms near Ladock, has planted strips of willow through some fields, allowing him to mob graze his livestock (regularly moving animals on from one small area of land to another, which is a great way of boosting soil biology and carbon storage).

Mob grazed cattle

Planting more trees across a farm, or allowing hedgerows to grow out, not only benefits birds, pollinators and other wildlife. This can also provide shade and shelter, important for livestock as our weather becomes more extreme, as well as additional fodder. Trees can also be coppiced to provide firewood or fencing materials, or could provide additional crops such as fruit or nuts.

Tree planting is often linked to something else that has spawned huge controversy – rewilding. Yet several farmers across Cornwall are involved in this to different degrees too, re-introducing extinct or struggling species from tiny harvest mice or water voles to larger and much more misunderstood ones, like beavers. 

There’s alarm in some quarters about beavers eating fish (they’re vegetarian) or killing trees (most of the trees they fell regenerate). Concern about flooding of farmland may be more of a possibility. However, experience in countries like Germany, where beavers were reintroduced over 60 years ago, has shown these animals can be managed and relocated quite easily if problems arise.

In terms of benefits, beavers’ leaky dams help to clean up rivers and drastically reduce flash flooding, while the ponds behind them have been proven to kickstart an amazing return of other life, from insects and fish to bats and birds. Importantly for farmers in our changing climate, they can also provide a valuable reserve of water for potential use in times of drought.

Turning challenges to opportunities

We’ve met so many Cornish farmers who are grasping the climate challenge with great enthusiasm – from the Stoke Climsland cluster of small farmers working together to create wildlife corridors across their wider landscape, to huge businesses like Riviera Produce, which farms 8,000 acres across Cornwall, producing a significant amount of the UK’s cauliflowers, cabbage, courgettes and kale.

By adopting more techniques such as companion planting to encourage natural pest predators, Riviera have managed to massively reduce the amounts of pesticides and other chemicals they use. Worm counts in their soils have boomed, and by using cover crops after harvest instead of leaving bare earth there’s now far less run-off from their fields to cause flooding in nearby villages.

But…. there is one big elephant in the room around farming and climate action in Cornwall. Just a cursory glance shows that most of our farmland is dedicated to livestock – and the climate impact globally of the meat and dairy industry is huge.

Livestock farming may be a traditional part of Cornwall’s heritage and it’s true that we grow grass here very well. However, many animals today actually live in highly intensive systems dependent on imported feed and chemicals, with their waste contained in vast slurry lagoons that pump out planet-heating methane. 

Innovative Cornish research is attempting to tackle these impacts – for example by capturing methane and turning it into a green fuel, or researching new feeds to replace damaging Amazonian soya.

These advances are important given that these mass-produced animal products are sadly much more affordable than milk or meat from higher welfare and more nature-friendly, pasture-fed animals.

However, it’s also important to recognise that nearly 10% of the UK population is now either vegetarian or vegan. Could this offer new diversification opportunities for Cornish farmers too? 

We already have more Community Supported Agriculture (CSA) schemes, growing veg to organic principles, than anywhere else in the country – but there is potential for much more horticulture here too. A changing climate may increasingly also enable us to farm more and different crops, such as sweet potatoes, soya and grapes.

At least one Cornish livestock farmer is even considering growing oats to tap into the vegan oat milk market too!

Farmers have always been great at adapting to whatever is thrown at them – be that weather, government policies or changing public tastes.

However, as climate impacts worsen, adaptability is going to become key to their survival. We all depend on farmers three times a day, so supporting them in this changing world should be a priority for all of us too.

We’ve seen some tantalising glimpses all over Cornwall of many ways in which farming could become more resilient and much better for nature, people and the climate. 

Making this a meaningful reality is clearly going to need much greater support from the government. However, we hope that, by showcasing the stories of so many passionate food producers around Cornwall, our films can help to enthuse more of the farming community to get on board with becoming part of the climate solution too.

Revisiting Rotmell Farm (Perthshire), Soil Farmer of the Year Winner 2020

Posted on December 2, 2024 by - Case Studies, Insights, Soil Farmer of the Year

Written by Becky Willson, Business Development & Technical Director

On a sunny day in September, farmers gathered at Rotmell Farm to take part in a farm walk with our Soil Farmer of the Year Winner from 2020. Thanks to funding from the AFN+ network, we have been able to revisit two farms this year to understand how their farm and management system has evolved since being awarded. 

Rotmell Farm is 1000 ha, 800ha of which is unimproved pasture – encompassing heather, bracken and wet areas.  The farm sits in the middle of the Tay Valley, and watching how water was moving through the landscape formed a key part of the decision to adapt the management of the farm to focus on soil health and water holding capacity. In order to achieve this the grazing management system was adapted in 2015/6 to include subdividing paddocks and starting to move stock. Since this time the farm has continued to evolve its management style until now where the primary driver for the farm is to use the stock to maximise carbon and nutrient cycling across the farm.  

Alex explained:

I had thought that the moment that we started putting in fencing, subdividing, moving stock and going into taller covers and rotational grazing that we could balance saturations of key nutrients and achieve a system where no inputs were required. We’ve built organic matter and are growing pasture, but the system needs to be continuously managed and adapted to try and achieve that balance. I now regard grazing as an art form.

The event started with a session in the barn to understand the evolution of the system and the key principles that the farm uses to drive performance. A key driver over the last couple of years for Alex has been understanding total nutrition and the ability to balance nutrients to enable optimal soil and biological health. This has involved implementing in depth soil analysis to understand the balance of key nutrients within the soil and intensive observation of plant and animal performance to start to understand how they are working together. This has included a focus on calcium as the driver for improving structure, oxygen levels in the soil, grass production and carbon cycling. 

The whole farm is set up for total nutrition. We are trying to get the biology working to grow high Brix grazing grass to feed to stock, to sell nutrient dense meats and other products into the local market.

The farm sells honey, eggs, and beef locally where the ability to connect the farm with the produce is valuable and helps to cement the farm as part of the local community and allowing them to identify with the produce and where it comes from. 

Alex has adapted his grazing system to encourage more diversity in the leys and to graze taller residuals. He sees far greater value in the hoof impact through trampling than the grazing; when the animals are put into taller covers, they graze the plants higher up and don’t graze the base of the plant, which leads to the carbon rich material being returned to the soil, cycling that carbon to feed the biology.  The intensiveness of movement of the stock helps to get the carbon back down into the soil. The tightness of grazing takes away selection of grass. 

The first field that we went to see has been used as an experimental field to look at species mixes. Alex researched different grass mixes and has returned to a mix that was common in the 1880s which can be used to improve poorer land. The field had been forage rape previously with lambs grazing the aftermath. The field was then disced and the new ley was broadcast, rolled in and then left. It has just had its third grazing, having been grazed with sheep 8 weeks after sowing to encourage it to tiller in late July. It was then grazed with a mob of about 65-70 cattle to break the parasite window and then had a group of 200 ewes with twin lambs. Every time seeds are sown they are mixed with vermicast, humates and fine lime which encourages biological activity around the seeds and ensures the seed has everything it needs to get going. 

Alex really sees the importance of a high seed rate which allows for a thick and vigorous sward but also helps to maximise the value of trampling. He is aiming for 285 plants per m2 and has seen this work well higher up the farm where it is increasing the density of grass and reducing coverage of moss.  

The animals have adapted well to the changing system. All the stock are out all year round, there is no housing. Bales are put out for the winter, with the aim being to set up blocks to shift the cattle every two to three days on a self feed basis. The type of cow has changed as the system has evolved; the animals that cope better in this system are slightly smaller framed and carry flesh. The cows need to be at 350kg at 15 months in order to allow them to calve at 2 years old at around 450kg in the middle of April outside.  Cattle are weighed and recorded regularly to monitor live weight gain and body condition and FEC tested every 90-100 days to monitor worm burdens. The sheep are also weighed regularly to provide insight into which animals and genetics are coping with the system. The sheep are supplemented with rock salt and minerals depending on the pasture and soil analysis.  

It wouldn’t be a soil farmer walk without a group of farmers standing over a soil pit and looking at the impact of the management changes on the soil. Alex has seen changes in soil health, since making the early transition to rotational grazing, however over the last couple of years has been focussing on enabling the biology to thrive and optimising nutrient cycling and the interaction between the soil and the plant roots. As such, two key assessment methods have been useful to show progress which have been the penetrometer and Brix assessments.

I started to get really excited about Brix readings a few years ago, and then really clocked onto it last year. I realised that the taller the plant got the Brix reading grew and grew, we started with 3’s and 4’s, as the covers got to boot stage readings got to 9’s and 10’s which was really exciting. This year, the penetrometer has been a useful tool, the pressure readings had been 250’s and 300 PSI and now we are down to 150, and I think that once we have psi’s of 150 then we are getting oxygen into the soil. We can send soil off to the lab for analysis, but how the soil is structured is a reflection of our management. 

If we find fields that are compacted, I’ll skip them and give them 120 days rest rather than 60 days. We have stopped treating the whole farm as one block and looked at what the field needs and how we can optimise root architecture and plant diversity. Its important to us that every grazing experience is positive.  We want to get to the point where we don’t need to apply anything, although we aren’t there yet. I’m not totally against applying anything, we need energy in the system and if the soils are tight, then we aren’t at optimal soil function, but the aim is to get to the point where we can target nutrition based on soil and plant need

Due to the nature of the farm and that 85% of the farm is hill areas, a key challenge for Alex has been to manage these areas in a way which can control the bracken ingress. He has been managing these areas in order to build capacity higher up, so that the in bye ground can be managed in a way to provide longer recovery periods.  

If I don’t keep enough stock to get on top of the bracken, I will lose the whole farm to it.  We only have 8-10  weeks to influence on that plant when it is above the ground, the other part of the year it is below the ground.  We have implemented a grazing system which is intensively extensive, really hard hitting when we are there – in the summertime we are moving cattle 4 times per day, but then really long recovery periods. Which allows us to knock the top cover of the plant back but not doing enough to impact the biology and chemistry of the plant – which is why we have just brought pigs onto the farm.

Where this has been implemented, the results have been remarkable. Where the bracken has been managed in this way, the pasture regrowth has been diverse – clovers, vetches and grasses alongside yarrow and red clover are now starting to emerge due to the management system. Although bracken in a challenge, Alex also sees the benefits of it when it is controlled as it is mobilising a lot of potassium around the system which can then be used to support the pasture regrowth. The management of these areas is crucial, where extensive management is leading to the development of these bracken areas,  

The base geology between our unimproved and improved land is exactly the same, so the  potential to increase output on that land is vast. The more I think about it, the more I think that soils don’t want to be extensively managed, they want to be intensively managed with long recovery periods. We produce a lot of disturbance and then get off it to let it recover.

The group then went to look at the pigs, the new tool in the bracken control strategy! The aim with the pigs is that their rooting activity will help to chew the roots of the bracken up and add manure to aid nutrient cycling. Following the pigs activity the area will then have seed broadcast to increase forage production. The pigs will also be moved into higher areas to help with the bracken control. 

The final stop on the walk was at some slightly higher country. The field had been soil sampled and the results had shown good levels of organic matter but suppressed levels of biological activity. As such, Alex is conducting some trials looking  at the efficacy of spreading fine lime as a way to improve the calcium content of the soil and enhance the biological activity. Analysis shows that there is most compaction on the farm in the in bye fields, higher up there is less compaction but lower pH’s and less biological activity; as such if we can grow more feed higher up then less forage is required. The farm is using half as much feed as they used to since transitioning to the system. The grass used to be very thatch dominated but there is now an increase in clovers and plantains starting to appear. 

Alex explained his change in thinking to manage for what you want rather than what you want to control.

I was so transfixed about managing bracken, I forgot to manage the grass. So by managing the grass, I build the quality nutrition and manage the soils to get the system working, then the pastoral density comes and will deal with the bracken.

To finish the walk questions turned to what next? Alex has spent the last 6 years gathering data, digging holes and persisting to pull it all together. So for the future, he thinks that the big changes have been done, its more about being observational and tweaking the system to optimise biology. 

Grass is the most undervalued crop and so we are starting to put it in through the introduction of the new leys. We aren’t carrying more livestock but we are spending a lot less money. Its taken me 10 years to understand how to manage this ground.  The failures have been too high- to learn about this we have to get some of it wrong, I’ve never had a year yet where we have got everything right but that is how we learn. Now its time to deliver what we know will work and to drive that system we need nutrition. We’ve been funded to experiment and now the system has to deliver.

Our sincere thanks to the Alex and the team at Rotmell for a fascinating afternoon that gave everyone plenty to think about.

Case Study: Ben Richards, Middle Trelan Farm, Cornwall

Ben Richards has been awarded Third Place in the 2024 Soil Farmer of the Year competition. This case study gives an overview of how Ben has built his system around resilient soils to provide the forage and nutrition his herd. If you would like to visit Ben’s farm, a farm walk taking place on 12 September 2024: click here to book your place.

Middle Trelan Farm is a 290-acre dairy farm in Cornwall, milking 180 to 200 cows, depending on the time of year. The farm has been certified organic since 2020, with the cows being 100% grass-fed, milked once a day, calved in spring from the 10th March and outwintered to reduce costs. 

Soil management has been a key focus on the farm for over 20 years, and Ben shares that making more money has consistently been a key driver in the steps taken to improve soil health and reduce inputs.

Early noughties – addressing nutrient imbalances and surface compaction  

As a wet farm with heavy clay soil, an early challenge in soil management was to alleviate surface compaction, which was achieved using slit aeration. 

Ben also took advice from Straight Line Nutrition, using recommended fertilisers to resolve nutrient imbalances in the soil. 

2010s – phasing out chemicals and introducing herbal leys  

Weaning off chemicals has been a gradual process at Middle Trelan Farm. In 2012, the decision was made to start gradually weaning off the high use of nitrogen fertiliser. Now, Ben focuses entirely on feeding the soil, not the plants, which he does by applying 2.5 tonnes/acre composted farmyard manure per year.  

Having switched from blanket spraying to spot spraying broadleaf weeds in 2005, spraying was stopped altogether in 2016. It took four to five years to increase dock beetle numbers to the point where they were controlling docks. Now, with the overall reduction in chemical use, the docks have become more palatable, so what the dock beetles do not eat the cows will eat anyway. 

Ben also started growing herbal leys in 2016, selecting species to benefit the soil, as well as those which will benefit the cows. This includes choosing deep-rooting species to improve the soil structure and enable water to permeate into the soil. Seed companies warned that cows would not eat some of the plants, such as sweet yellow blossom clover, but in practice, Ben has found that as the soil has improved and plants become more palatable as a result, the cows will eat all species. He has not included any ryegrass in the mix for over five years, with the exception of during Covid when the seed companies were not able to source an alternative. 

For reseeding herbal leys, cows are now grazed on the area to be reseeded over winter, followed by pigs. The pigs turn over the soil and root around, preparing the ground for establishing a herbal ley in the spring.      

The cows have benefitted from the move away from chemicals and the introduction of herbal leys, as they can self-medicate by selecting the nutrition they need. The evidence for this is clear, as Ben has not needed to treat the cows with any medications for eight years, although he does still give the calves an anthelmintic for lungworm. 

The phasing out of chemical inputs, from broadleaf herbicides to veterinary medicines has reduced costs and therefore improved farm profitability. 

2020s – moving from a bacterial soil to a fungal soil 

Ben shares that it was 2021 to 2022 when the farm turned around – it had reached the point where it had a fully functioning bacterial soil. The focus has now shifted to move to a fungal-dominated soil, as with fungal mycorrhizal structures present plants can cooperate, warning each other of dangers and contributing to the overall health of the farm ecosystem. 

The presence of deep-rooting plants will facilitate the transition to a fungal soil, so Ben has embarked on an agroforestry project, which is funded by Forest for Cornwall. The project began in 2023 to 2024, when 6,500 trees were planted in 1.5m rows (3 trees across 1.5m), with 12m between rows, which should be close enough for the fungal mycorrhizal structures to reach each other. Grazing trees were selected, including different varieties of willow, poplar and aspen. 

The wettest fields were chosen for tree planting, with the intention that the trees will also help drain the fields, getting rid of surface water. Herbal leys have been planted between the tree rows, so in year two the trees will be grazed together with the herbal leys. 

Another 4,000 trees will be planted this winter. In year three, Ben intends to stop planting and wait to see the impact during a full grazing season, then if it is working as expected he can take cuttings from the existing trees and roll out the system across the whole farm.    

Ben explains that the overall goal of the agroforestry is to maximise dry matter production on-farm to feed the cows, while the trees will also help drain the fields, promote fungal activity in the soil, secure a reliable forage supply throughout the summer and also provide nutritional benefits to the cows eating them. In short, the trees should ‘tick all the boxes’ for farm resilience now and in the future. 

To conclude, Ben shares that he has found it to be true that ‘less is more’. The less interfering he has to do with the cows, the better their life is, and the better his is too.    

Soil Farmer of the Year 2023 – Farm Walk with Richard Anthony 

Posted on April 18, 2024 by - Case Studies, Insights, Soil Farmer of the Year

Written by Tilly Kimble-Wilde, Farm Carbon and Soil Advisor

Richard Anthony, of R & L Anthony near Bridgend, was awarded Second Place in the 2023 Soil Farmer of the Year competition. He was commended on how he responded to and managed challenges, never veering from thinking holistically, always upholding soil health as a priority, and treating each challenge as something from which to learn.

A majority arable business, Richard farms a 6-year rotation of wheat, maize, oilseed rape and westerwolds intermixed with a diverse array of cover and companion crops which he is passionate about. “The emphasis on farm is the soil, improving the soil and organic matter, and keeping a crop in the ground; keeping the soil biology alive.”

Richard and the team also strive to promote and create habitats for wildlife: planting wild bird seed mixes, establishing wildlife corridors, and bordering all hedgerows with a 3m margin to encourage growth year on year. 2m flower margins have also been implemented around all fields of oilseed rape which has been, to quote, “absolutely fantastic.” Encouraging insects and bees and getting the public on side too.

The farm walk itself took place on 23rd November 2023 and kicked off with a presentation taking us through the past year and outlining the various activities and obstacles the farm faced. We were then treated to a fantastic farm walk whereby Richard gave our group of visiting farmers, agronomists, and advisors a tour of some of what they get up to across their extensive arable and forage business.

A big part of what Richard and his team are trying to achieve across the farming business is to use very little bagged fertiliser. Most of the nutrients applied to the soil come from digestate, conveniently stored in the farm’s digestate lagoon. Tankers come in and fill alligator bags for easy transport and the digestate is spread on wheat, oilseed rape and maize.

So far, Richard has managed to eradicate artificial fertiliser when growing maize and OSR; however, wheat still receives a small amount of early application. This wouldn’t have been possible without the construction of the digestate lagoon, a project which was undertaken at the beginning of last year. Still, as Richard says, there is room for improvement. The farm is looking to reduce its N inputs even further by trialling an N inhibitor, all to build more resilience into the system.

This mindset has been applied to fungicides.  To use less, Richard has changed the sprayer to accommodate the wet and windy weather brought in from the coast. Now at 250cm spacing, the booms can run very low resulting in no drift even if it’s windy. This enables more spray days and a better chance at getting the timeliness right.

As with most farms across the UK, the weather has been the biggest challenge with dry weather in May and June, and then rain as soon as harvest began.

Luckily, Richard had installed a biomass boiler 6-7 years ago for grain drying after a very wet harvest having heard about them in Scotland. It has been a game changer. Their 1-megawatt biomass boiler provides a lot more spare heat than previous methods of grain drying where they used up to 1.2 megawatts of gas on one drying floor. In the old system, if they were on 25% moisture, it took 10 days to dry one side. With the biomass boiler on woodchip, they can dry 2 drying bays, double the output, and never have to run the boiler flat out. With the right combine (Richard uses a MacDon belt header), the corn is cut as soon as it gets to 25% and achieves good output, as Richard emphasises “do not wait”.

Planting OSR in August was a struggle, with some fields too wet to put a tine in and any cultivation out of the question. Instead, Richard planted the wet parts of the field by snipping the OSR with a sprinter drill and planting the dry parts with a farm standard drill and a top down.

To better manage the unpredictable weather, Richard has a selection of drills that he’s held onto rather than sell. The farm will run 2, sometimes 3 drills if they can, capitalising on days when they have the right weather. This was especially helpful during autumn when the farm received 295mm of rain in October alone.

The farm also spends a lot of time on drainage. Ditches are cleaned, dug out, drains put in; all with the aim of evening out patches in fields and making the farm more resilient. As Richard says, it’s great getting 16t/ha on wheat in a bit of field but if you’re only getting 3t/ha in another part because it’s too wet there is space to do better.

Still, the most used bit of kit on the farm is a spade.  By continually monitoring and assessing soil structure, Richard can make a well-informed decision when determining how to establish the next crop.

Farm Walk

During the farm walk, we were shown multiple cover crop and companion crop trials that were taking place on the farm. Steve Corbett from Agrii has worked with Richard for many years, trialling different varieties and combinations, highlighting the importance in being selective. You need good establishment, and it must earn its keep.

What they have found is that OSR, a “lazy rooting brassica”, completely lends itself to companion cropping, in this case with beans, spring vetch and buckwheat. Beans help to get the roots down as well as provide free nitrogen through nodulation. Spring vetch as opposed to winter vetch grows quickly providing biomass and N fixation. Buckwheat adds to the canopy, slowing down flea beetle, making it more difficult for pigeons to land, as well as mining phosphates. When the companion crops die, all the fixed nitrogen and phosphates will be released back into the soil ready for the next crop.

Richard deliberately plants OSR at low seed rates to encourage big branchy plants in spring which will grow away, allowing light through the canopy. By choosing thicker and well-branched OSR types, flea beetle is more contained, damaging only the outer leaves, leaving the middle to branch out. In Richard’s experience it provides a plant that will survive despite a pest living within it.

In terms of cultivation, Richard is a big fan of direct drilling. When direct drilling wheat, he believes it is important to see what is happening underground: what is the root depth? Taking stock of root depth and maintaining that attention to detail during crop growth is essential to determine the next steps in terms of cultivation. At Sealands farm, root depth is critical to survive the winds, Richard has found through monitoring that cultivation disrupts root growth, and that direct drilling fits his system best.

Ultimately, Richard has tried a lot which didn’t work out, but he’s kept at it. One outcome which has surprised him the most was the success of forage rye which he believes is underestimated. In the field, Richard showed us the root mass it was building and the excellent soil structure it yielded. This has provided Richard with an extra income stream, either taken for silage or grazed (ensuring to move stock on in wet conditions to avoid undoing all the good work he’s built up!).

Looking to improve the soil structure even further, Richard planted the forage rye together with westerwolds. He found that they were able to harvest the westerwolds a fortnight earlier due to the ability of the forage rye to get away in the spring creating its own microclimate which Richard believes benefitted the westerwolds.

Finally, we heard about Richard’s problem with persistent perennial ryegrass. In this instance, he introduced an annual ryegrass to outcompete the perennial. “Putting in a bully to outcompete a bully”. It worked and Richard is now able to include it within the arable rotation without generating a loss. This allows a rest period within the rotation to build fertility, stabilise soil structure and generate a bit of extra cash from silage or grazing. Essentially, Richard is maintaining the balance of farming resiliently: optimising soil health and crop yields while sustaining a viable business.

As we’ve all come to realise, we can’t rely on the weather, however, prioritising soil health as perfectly exemplified by Richard, can better equip us to respond and adapt. When we get to know our soils, monitoring how they behave in certain conditions and how they respond to our actions, we are better prepared and forearmed to make decisions that will affect future harvests and pocket.

Through trials and problem solving, Richard together with Steve have implemented more diversity and reduced inputs without damaging profits. A big resistance to straying from our well-known and “safe” rotations is often down to “how will it pay for itself”. Richard and Steve have shown that they’re not radical in their rationale for cover and companion crops, the bottom line is it has to pay. The most exciting take home from the day is they didn’t give up: they’ve found the right species to incorporate, the soil health on farm is improving and crop yields are directly benefiting. It was a truly inspiring day and a masterclass in perseverance. Richard hasn’t made it look easy by any stretch but as he puts it “we’re just learning all the time.”

Soil Farmer of the Year 2023 – Farm Walk with Bronagh O’Kane

Posted on January 4, 2024 by - Case Studies, Insights, Soil Farmer of the Year

Written by Emma Adams on behalf of The Farm Carbon Toolkit

In a first for the Soil Farmer of the Year competition, in October 2023 our series of farm walks took place in Northern Ireland. A group of farmers, academics and industry professionals met at Drumard Farm, just outside Cookstown in County Tyrone, to hear from Bronagh O’Kane on how she is transforming her farming business with resilient soil at its heart.

Bronagh introducing the farm to the group

Having come back to the farm in 2020, Bronagh began a journey to transform the soil. Historically the farm supported continental cattle breeds with a high reliance on imported feed, Bronagh has transitioned this system to more traditional breeds managed on herbal leys and ever-increasing diversity grasslands. Utilising a rotational paddock system she has extended the grazing period so that cattle can be out by 4 weeks and soils are more resilient to the extremes of dry and wet weather. Bronagh has started producing vermicast and composting to improve soil biology; focusing on natural inputs and a softer approach with foliar fertilisers where needed to manage historically compact and imbalanced soils. The walk will provide the opportunity to discuss and demonstrate the practices undertaken at the farm and the ongoing challenges and successes that Bronagh sees in her system.

The beginning of the farm walk

At Drumard Farm, Bronagh was told she had poor soils and no doubt they are a challenge, with testing suggesting an average of 45% silt and 45% clay they are tight and sticky, with little aggregation or infiltration. As such, understanding what was needed for the soil to function better was a priority for Bronagh, with a great deal of research it was understood that the high magnesium, bacterially dominant soils were being held back by a mineral imbalance, compaction from big tractors and heavy cows. 

Inspecting the soil condition following the autumn rain

Changing the livestock system at the farm has been central to Bronagh’s evolving management. The cattle business has been streamlined, and as such the previous finishing and store systems have been stopped instead to focus on a suckler system with pedigree Charollais sheep. The sheep are high value stock, as Bronagh suggests there isn’t the acreage for a larger flock, instead, she buys in September before selling the ewes with lambs at foot in the spring and runs the rest of the flock throughout the year. This system works well as there is the housing space available over winter and also the sheep provide a good opportunity to clean up the last of the grass when it is too wet for the cattle to graze. Previously the farm also had Charolais cattle, but these have been restocked, reducing numbers from around 80 to 50 on a sucker system focussing on more native breeds such as Speckle Park, Shorthorn and Hereford crosses with an Angus Bull. Even with these changes, Bronagh found that those animals with a Limousin cross within the breeding still comparatively lost condition on the new system which is thought to be from underlying epigenetic traits. This has led Bronagh to source more local Shorthorn heifers which are better adapted to a grass-based system. 

Bronagh utilises plant diversity as an indicator of the status of the soil. The species that may dominate in a field or area can suggest what the underlying composition may be – chickweed for excess nitrogen, low calcium or high potassium or creeping buttercup thrives where there has been poaching, bare soil and a low pH. Like many farms, docks have historically been widespread at the farm, often indicating compaction and an anaerobic soil environment. Bronagh’s approach to dock management is to change what has historically not been working – sprays and topping – and instead let them grow and allow the dock beetle to get to work combined with a cut for silage around June. This understanding of what the plants are indicating has led Bronagh to stop spraying and minimising fertiliser use to zero, instead focusing on balancing the soil and improving the health of the biome. She explains:

“Biodiversity, long rest periods and grazing management can change soils – you’re not stuck with what you have”

Grassland management is central to how the business is now run. Bronagh has diversified existing grasslands into multi-species swards despite the testing conditions and low pH of the farm. On the walk, the group visited a newly established herbal ley that had been planted in a field that was pH 5.8.  

The newly established multi-species herbal ley

The 15-way mix contained species such as sainfoin, plantain and chicory and Bronagh has subsequently experimented with both cutting and grazing, which has led to discussions with contractors on cutting heights, timings and more to best maintain the sward. For Bronagh, managing these lays to allow the full diversity is important, with the understorey plants encouraged through the aforementioned considerations in combination with the paddock grazing system. Bronagh has experimented with the paddock grazing timings and methods, including grazing the cows on knee-high swards which resulted in moving them faster but increasing the size of the paddock as the cows were found to be trampling rather than eating following heavy rain. Bronagh suggests:

“The definition of overgrazing is letting them get that second bite – it is so important for my fragile, shallow roots to rest”

In addition to the home farm, Bronagh also has a 30ac National Trust tenancy on a zero-input system supporting both a rotational grazing and cutting platform. For Bronagh, having the right livestock that will thrive on a grass based system is key to success. As such, she puts the heifers on the poorest fields to determine which animals will be kept as some breeding is adapted better to the system than others. 

The walk also incorporated learning more about how Bronagh is using vermicast to provide nutrition and balance to her soils. Vermicast, or worm castings is made by using worms to compost organic amendments such as farmyard manure, food waste, wood chip etc to create a soil conditioning fertiliser.

down to create the vermicast

On the farm, vermicast is used to provide nutrients, stabilise pH and also as a coating on any new seed that is established. Bronagh applies her vermicast through a sprayer after making a ‘compost tea’. The vermicast is added to a porous ‘tea bag’ within an IBC filled with water which is then agitated and aerated using a bubbler to extract the nutrients and beneficial organisms which vermicast contains, the resulting liquid is then applied to land to stimulate soil biology and provide nutrients. Bronagh is aiming for a 1:1 ratio of fungi to bacteria which the vermicast and good soil management will help promote.

Bronagh explains the process of using vermicast
to make a compost tea

Regularly conducting Brix testing has allowed Bronagh to understand how to best apply the vermicast and the benefit it is having to her land, with fields which have had no fertiliser, slurry or inputs other than vermicast scoring 12, with Bronagh suggesting that every 1% increase in a Brix result can give a 0.5-0.75kg improvement in liveweight gain in the cattle. Any amendments which Bronagh applied to the land are designed with this goal in mind, alongside the cost and feasibility within her system. An example of this is that she has been experimenting with using egg shells to help aid the calcium balance and flocculate the soil; this can be spread with a conventional fertiliser spreader rather than other products which can have additional costs due to the price of both material and the contractor required to apply the product. 

Since 2015, the Soil Farmer of the Year Competition has helped to find, promote and champion UK farmers who are passionate about safeguarding their soils and building resilient businesses. As part of the competition, the top three farmers host farm walks that bring farmers together to share good practice and innovations that improve soil health. The 2024 round of the competition opens on 5th of December 2023, which is World Soils Day – if you are interested in finding out more, entering the competition or nominating someone who you think is deserving of this award further details can be found on the Farm Carbon Toolkit website or https://farmcarbontoolkit.org.uk/soil-farmer-of-the-year/ 

Lessons Learnt at Erth Barton

Posted on December 14, 2023 by - Case Studies, Farm Net Zero, Insights

Wednesday 18th October 2023

Tim Williams has now completed three years of a contract farming agreement with Antony Estates, working to convert Erth Barton into a regenerative farming system, rebuilding soil fertility. This event was a chance to hear about some of the successes and challenges encountered during the transition. This event was made possible with thanks to the National Lottery Community Fund who fund the Farm Net Zero project.

Tim took on the 300-acre (121 hectare) farm in two halves, arriving with very little kit and limited funds for inputs. This has meant he has built a simple, zero-input system focusing on restoring and feeding the soil microbiology in order to provide fertility.

A very diverse cover crop/herbal ley was drilled to increase rooting depth and diversity and then grazed with beef cattle (averaging 0.8 Livestock Units per hectare) with the aim to eat a third, trample a third and leave a third. Tim has learnt that it is best to focus on managing grass to build up a reserve rather than eating into it. Frequent moves leave grass to regrow, meaning there is always grass ahead of the livestock throughout the rotation.

Another method Tim has trialled to improve soil microbiology has been applications of compost created using a system called “complete microbial composting” developed by the Land Gardeners. This involves mixing brown (cattle dung, soil, straw) and green (fresh cut plants) material from around the farm in long windrows and turning. Three methods of application were trialled – direct spreading, compost tea brewing and “biopriming” (mixing compost with the seed prior to drilling). Tim felt that the biopriming technique has the potential to be the most successful. However, soil microbial testing conducted by the University of Exeter showed no difference so far between areas with and without compost application.

Tim has also experimented with pasture cropping alongside WildFarmed, this involved using a Moore Unidrill to direct drill a heritage wheat blend into a hard-grazed herbal ley. The aim was for the existing ley to provide ground cover and nitrogen-fixation. Tim described the first attempt at pasture cropping as a “disaster”, with chicory swamping the wheat and making harvest impossible. A second attempt meant tweaking the herbal ley mix to make it less competitive, grazing tight, sub-soiling and spring tine harrowing for seed/soil contact and then direct drilling. This appeared to have good establishment up until May, at which point Tim noticed that about two-thirds of the crop was Westerwolds grass. Again, harvest was abandoned and the field grazed instead to utilise the crop and keep organic matter in the field. In future, Tim plans on removing grass from the mix and replacing with a species that has more winter-kill such as sunflowers/millet/sorghum.

As Tim’s time at Erth Barton draws to a close, we would like to thank him for his work on Farm Net Zero and wish him all the best for his future endeavours.

Key takeaways:

  • Bringing pasture and livestock back onto the farm has helped to improve soil quality.
  • Fertility extraction should be balanced with fertility building. This can be done as part of a rotation.
  • Even when experiments do not go the way we first thought, we can still learn valuable lessons from them.

The Fellfoot Forward Project: A Case Study

Posted on December 7, 2023 by - Case Studies, Insights

In December 2021, five farmers from the Fellfoot Forward Landscape Partnership participated in a carbon footprinting project in association with the Farm Carbon Toolkit. Based in proximity to the North Pennines AONB these five upland businesses demonstrated how livestock farming can work in conjunction with the wider landscape to produce quality food whilst providing environmental services such as water and air quality alongside carbon capture and storage. 

A carbon footprint, or carbon balance, is the measure of the total emissions and total sequestration associated with a particular business or product. For this project, the whole farm was measured to include all of the enterprises included within a farming business. When we discuss ‘carbon’ we are referring to ‘CO2e’ or ‘carbon dioxide equivalent’ which is a measure of the three main greenhouse gases carbon dioxide, nitrous oxide and methane. Different greenhouse gases have different dynamics within the atmosphere, consequently having higher or lower warming potentials and thus potency as a contributor to climate change. Therefore, ‘carbon’ as a term encapsulates all three of these gases under one metric so we can compare items such as fuel alongside the biological systems seen in livestock like for like.   

To produce a carbon footprint the farmers were asked to collect a variety of data associated with their business, including items such as fuel and water usage, livestock numbers and quantity of materials used for activities like silage wrapping or maintenance. Alongside these figures, it was also important to record the ‘natural capital’ of each farm holding – the resources found in the farmed environment which are managed as part of the business but provide wider ecosystem services and value – such as areas of woodland, length of hedgerows, soil organic matter and specific habitats such as floristically enhanced margins or wetlands. When all of these details had been recorded, the data was entered into the Farm Carbon Calculator to produce a carbon footprint detailing the balance of emissions and sequestration found at each farming business. 

For the farms included in the project action plans were created to highlight where emission savings can be made or sequestration opportunities maximised. All of the farms within the project were found to be likely to be able to reach a Net Zero, if not already in this position. A large factor on many farms to reach this target is proper accounting of carbon held within the soil as organic matter. For the Fellfoot Farmers who are in majority grassland systems, livestock can be utilised as a tool to increase organic matter in soils – either through grazing systems and the capture of sunlight to be stored as carbon, or through the return of manure to pasture for nutrient cycling. To fully account for the potential sequestration of carbon through the building of organic matter in soils regular testing should be conducted to measure and monitor the levels found in soils. If, like on many farms there has been no prior soil organic matter testing the best advice would be to select three or four key fields within the farmed area which are representative of the systems within the business. For example, if the farm was in a grass-based system, a field which is usually cut for silage, one only grazed and a traditional low-input or hay meadow would demonstrate potential underlying trends in organic matter across the landscape. Equally, if there is a range of soil types or diversity of land use on a single farm it would be perhaps useful to test fields representative of these features to better understand trends and consequently the best management approach to conserve existing carbon and build stocks in the future. As ever, when testing soils aim to minimise external variation by ensuring consistency in the laboratory used and the time of year when sampling.   

The project with the Fellfoot Forward farmers demonstrated the variety of approaches to upland livestock farming, from the number or type of stock to the management required to protect and enhance vulnerable habitats within their farmed area. Some of the farms included in the project had areas of peatland within their management, using cattle or sheep to maintain and conserve the landscape in association with government or local schemes to the benefit of the wildlife and ecology found there. Peatlands are a vast store of carbon and consequently, the condition of this landscape could greatly impact upon the land managers responsible for its status. More information is required to fully understand the dynamics of peat and how farmers can measure and monitor this landscape for not only carbon footprinting processes but also for generations to come. 

Carbon footprinting is a process that can be repeated on an annual basis, used as a monitoring tool for both the emissions and sequestration of a farming business but also to understand changes in management approach. There is a general underlying correlation between high carbon and high cost on many farms, with items such as fertiliser and blended livestock feed being both expensive and also a comparatively larger contributor of emissions. Therefore, conducting a carbon footprint not only has benefits towards understanding the environmental impact of a business but also can be used as a tool for resource optimisation and economic efficiency. 

Key findings

  • Conduct organic matter testing to understand the current carbon held within soils. Aim to repeat this testing every 3-5 years to understand whether your soils are sequestering (increasing in organic matter) or emitting (decreasing in organic matter) carbon. 
  • Account for things you are already doing such as hedge or tree planting that are under existing or future schemes.
  • Accept that you may not have all the data, aim to create a baseline from which you can repeat the process in future years and account for more information with more experience, time or understanding.
  • Identify ‘hotspots’ where emissions are highest. Except for cropping or livestock, are there particular items or categories which contribute a larger proportion of emissions than others, is there potential for reduction in these areas?

Carbon Farmer of the Year Farm Walk at Lockerley Estate, Hampshire – May 2024

Posted on June 6, 2024 by - Carbon Farmer of the Year, Case Studies, Insights

In May 2024, the Farm Carbon Toolkit were delighted to hold a farm walk at Lockerley Estate in Hampshire, home to one of the finalists from our 2023 competition. We would like to thank the Estate Manager Craig Livingstone and one of the owners Sarah Butler- Sloss for being so generous in hosting the farm walk.

Everyone who attended the farm walk heard from Craig and his team on how he has managed to make significant reductions in business greenhouse gas emissions, enhance the farmland biodiversity and enhance business performance.

Introduction

Craig Livingstone took on the role of farm manager at Lockerley Estate, owned by the Sainsbury family, 9 years ago with the challenge to improve biodiversity, sequester carbon, increase the health of the soil, and make a profit. To achieve this, a mission statement was devised with a list of objectives that really helps the whole estate team to work collaboratively to achieve the farm’s goals.

With just under 2,000 ha in Stockbridge, Hampshire, Craig farms Lockerley Estate and Preston Farms as one, which includes arable, grassland, woodland, a veg shed, and pockets of countryside stewardship schemes and SFI options. The farm is also part of a joint venture sheep and cattle enterprise, gaining benefits from grazing and muck which is integrated into the arable rotation. 

Over 9 years, Craig and his team have managed to vastly reduce emissions by transitioning to zero till and reducing artificial fertiliser and chemicals by broadening the rotation and integrating livestock. Specifically, Craig has saved 56,000 litres of red diesel annually and reduced pesticides and N-based fertilisers by 46% and 53% respectively. Soil organic matter has also increased by 1.1%.

Despite focusing on biodiversity, carbon and soils, Craig’s number one priority is profit – every hectare must pay for itself. Where he can, countryside stewardship schemes have been stacked with SFI options to increase profits. In some cases, the options available have encouraged Craig to adopt techniques that, for example, provide integrated pest management because the overall payment in combination with reduced pesticides is more than the potential loss in yield.

Currently, there has been a 17% change in land use, however the farm is still producing 9,000t food (approx. 4.5t/ha). So how has Craig managed to take the farm and reduce its emissions and increase soil organic matter?

Here are some of the highlights from the walk:

Arable

Using a broad and diverse rotation and choosing varieties that require fewer inputs, Craig has managed to halve the farm’s emissions due to vast reductions in fertiliser and pesticides. This in part has been achieved through implementing a mixture of winter and spring cropping interspersed with diverse mixes of cover and catch crops; legumes such as peas and beans; rotating grasses and legume fallow. The farm is also experimenting with clover understories and poly-cropping, prioritising diversity to build fertility and maintaining cover and living roots in the soil at all times.

The farm’s transition to no-till, aided by a zero-tillage seed drill, has also resulted in improved soil health and structure, increasing porosity and facilitating better water infiltration and enhanced soil biological activity through less disturbance. A multi-pronged approach to reducing fuels and fertiliser usage.

Encouraging diversity

As mentioned, the farm has taken advantage of environmental schemes such as winter bird feed (AB9), flower-rich margins and plots (AB8), and nectar flower mix (AB1) for multiple reasons. In short, to connect the woodland and encourage a host of wildlife, provide integrated pest management, and to make land more profitable.

Perhaps most interestingly, the team have implemented 6m assist strips of AB8 within a select few arable fields to encourage pollinators, beneficial insects, and predators. The initial cost of the seed is expensive; however, in this instance, the farm is not looking to reseed any time soon (especially within the duration of the agreement). That combined with savings on pesticides, they have found it far outweighs the cost of seed – it makes business sense. 

Craig has also looked critically at areas that are susceptible to weeds, difficult to graze, areas where the land lies wet, or where the shape of the field is awkward. Here, he has taken land out of production and implemented AB1 or other schemes to benefit wildlife and pocket.

Composting

A big project on the farm is taking cattle FYM and producing a superior product in solid compost and liquid extract using the Johnson-Su methodology. Agricultural soils tend to be bacterially dominated through repeated cultivations and chemical inputs but this process favours fungal communities which are excellent at cycling nutrients, disease suppression and soil aggregation. 

Good quality cattle muck is mixed with clover bales, straw, and woodchip, and through a series of steps breaks down into a fungally dominated compost. 

Once ready, a compost tea is created by placing a mesh bag full of compost into an IBC of water which is left to steep. This produces a highly nutritious and microbially active substrate which can easily be spread during drilling (rip and drip) and goes a lot further than the compost itself as well as reducing reliance on bagged fertiliser.

Veg Shed

Set up three years ago with a strong commitment to benefitting health, community, and the local environment. The veg shed is made up of 2 acres, 3 polytunnels, 40 laying hens and a fruit cage. The garden grows 50 different fruits and vegetables which it sells to local businesses on a wholesale basis but mostly through a local veg box delivery service.

Everything is grown from seed using heritage and heirloom varieties which have more diversity, and from testing, seem to have more nutritional value. They are also more resilient to a changing climate responding better to drought and high rainfall and requiring less inputs than other high yielding varieties.

The garden is designed as a polyculture and receives no artificial inputs, instead utilising compost from the farm and enlisting the help of dynamic accumulators to extract and release nutrients from the soil.

Wood pasture and Woodland

Linking SSSI woodland and calcareous grassland, the farm took advantage of the woodland pasture creation scheme and introduced longhorn cattle to graze instead of taking silage and hay. The aim is to create a large grazing area of species rich grassland and wood pasture that joins with 220ha of woodland improvement.

There is over 300ha of woodland at Lockerley Estate including a portion of semi-natural ancient woodland. The improved woodland is periodically thinned whilst retaining canopy cover to maintain diversity. Timber is harvested and removed with a percentage of profits returned to the estate.

The biggest outcome has been the flourishing biodiversity and wildlife. Diverse grassland is growing out from the hedges and wildflowers are starting to recover, blending into the woodland, and creating a mosaic landscape. Bird surveys see an increase in species year on year and botanical, butterfly and grasshopper surveys with fixed point photography are ongoing.

Hedgerows

Last but not least, Lockerley Estate takes great pride in its hedgerows, planting 12,000 hedgerow plants in the last year. Cutting regimes have also been lengthened to support all wildlife, from insects to birds to small mammals. This is made possible by replacing the hedge cutter with a saw blade to accommodate the thicker branches; the trimmings are then used for ramial woodchip in the composting process.

Summing up

Overall, it was a thoroughly enjoyable day and an interesting insight into how Craig and the team manage to maintain a balance between a thriving farm both in terms of biodiversity and bottom line productivity. Craig has demonstrated that economic resilience can go hand in hand with reduced inputs and tillage without compromising on food production. Entries to this year’s Carbon Farmer of the Year competition close on the 14th June, so  if you believe you are reducing on farm greenhouse gas emissions do enter our competition here
