Groundswell all set for bumper 2021 event
Atransformed venue will greet visitors to this month’s Groundswell event – the agricultural show focused on notill techniques and soil regeneration.
The fifth annual Groundswell show and conference takes place on 23-24 June at Lannock Manor Farm, Hertfordshire. It will include a host of ideas on ways to farm while regenerating the soil in the new environmental and political climate.
The overriding theme is set by the principles of regenerative agriculture. Workshops and exhibitions will include sessions by a range of innovative farming companies and field scale direct drill demonstrations.
New era
Taking centre stage will be two new exhibitor and demonstration fields. All sessions will take place in temporary structures dotted between the exhibitions.
Defra secretary George Eustice will be interviewed by former Fleet Street editor Baroness Rosie Boycott. Defra senior civil servant Janet Hughes will discuss how farmers will be rewarded under the government’s Sustainable Farming Initiative.
Host farmer John Cherry said: “The government’s stated ambition for the future of food, farming and the environment is that public money will be spent on public goods that enhance natural capital.
“The new Environmental Land Management scheme will usher in a new era for farming. For any farmer looking to adapt to this scenario while maintaining viability as a food producer, Groundswell is the place to be.”
Keynote conference sessions and rainfall simulator demonstrations will take place in a big top tent. The Earthworm Arms Bar area has evolved with live music taking place on the Wednesday evening and dozens of independent food traders.
Special sessions
More than 100 sessions will take place over the two days. Attendees will hear from a range of people in regenerative agriculture. Visitors will learn about the different principles and techniques – and how they are interpreted by different practitioners.
On stage will be leading soil scientists discussing with innovative farmers about how they are building organic matter and making their farming systems more resilient. There will also be debates on the future of farming policy.
A series of motivating talks and workshops with farmers outlining their strategies for regenerative agriculture – whether through growing more nutritious crops or changing their business to operate more holistically.
Nearly half the attendees to Groundswell believe livestock are key in a truly regenerative system. Sessions will range from building soil carbon in pasture farming to the birth of regenerative dairy farming.
Visitors will have the opportunity to learn how to maximise the value of a carcass with advice from veteran butcher Richard Summers. They will also be able to see how pasture-based livestock producers took on the vegan movement at their own game.
Expanding this theme, Groundswell is trying to help connect the dots between farmers and consumers. This year – more than ever – it is looking at different models for vertically integrating the supply chain.

• Take action to ease financial strain • Loss of payments poses challenge • Yield is king approach doesn’t work
Regenerative agriculture can achieve similar financial results to traditional arable systems and benchmarking your business can help to manage the change.
Farming is embarking on a period of huge change that most growers and livestock producers have never experienced, says farm consultant Gary Markham, who helped initiate the Groundswell Benchmarking Group.
This will see the industry move away from the comfort of area payments – which make up around 84% of income on many arable farms. Instead, farms will have to apply for specific funding for environmental work.
“This will inevitably put farming business in financial strain as there will be a funding gap over the forthcoming few years,” says Mr Markham. “Farming has become very capital intensive.”
Inevitable change
Mr Markham, of the Land Family Business farm consultancy group, will explain his thinking further at Groundswell 2021. “Change is inevitable – but managing the change is where the difficulty comes,” he says.
The economic production value of arable land is about £4,000 per acre and the additional £4-6,000 has no bearing on production capacity. Added to this is the increase in the capital cost of machinery over the past few years to over £300 per acre.
Many farmers have quite correctly attempted to expand as a means of dealing with these pressures, says Mr Markham. But this has normally meant tendering for contract farming agreements and losing about £40-60 per acre on the extra land.
This results in many arable farms becoming increasingly unviable as businesses. The margin from arable farming before direct payments and income from other enterprises has been minimal over the past two years.
“One of the best tools to monitor the change and provide achievable targets is to benchmark against farming businesses that have already made these changes,” says Mr Markham, who set up the Groundswell Benchmarking Group.
The group has been benchmarking a number of regenerative agriculture farming businesses for the 2017 to 2020 harvests – to identify if regenerative agricultural production systems can be financially viable.
Key findings for the performance of regenerative systems include: • Average output 25% lower • Variable costs 24% lower • Gross margin 28% lower • Labour and machinery costs which are 30% lower
This results in an average margin very similar for both systems of production. But the range of results within the group is wide with the top performers achieving results well above conventional top 25% group.
In addition to margins, there are savings in working capital of around £148 per acre which can have a large impact on a farming business.
Lack of profitability in arable farms is mainly driven by high machinery costs and in particular depreciation which represents the capital per acre. Mr Markham has therefore developed a key indicator of machinery capital per tonne.
The average machinery cost among the Groundswell group of regenerative farmers is £74 per tonne of wheat. This compares with an average cost of about £91/t for arable farmers employing a conventional production system.
“The difference has been around £20 to £30 per tonne over the past four harvests.” says Mr Markham, who says it shows that the traditional ‘yield is king’ philosophy does not work.
It also shows that expanding the area farmed is not feasible by using traditional contract farming structures he adds. Furthermore, Mr Markham says benchmarking data proves that there is a different approach that is economically viable.
Traditional contracting agreements will be barely viable without basic payments, says Gary Markham
Five principles of regenerative agriculture
1. Don’t disturb the soil
Soil supports a complex network of worm-holes, fungal hyphae and a labyrinth of microscopic air pockets surrounded by aggregates of soil particles. Disturbing this, by ploughing or heavy doses of fertiliser or sprays, will set the system back.
2. Keep soil surface covered
The impact of rain drops or burning rays of sun or frost can all harm the soil. A duvet of growing crops, or stubble residues, will protect it.
3. Keep living roots in the soil
In an arable rotation there will be times when this is hard to do but living roots in the soil are vital for feeding the bacteria and fungi that provide food for the protozoa, arthropods and higher creatures further up the chain.
4. Grow diverse range of crops
Ideally at the same time, like in a meadow. Monocultures do not happen in nature and soil thrives on variety. Companion cropping (two crops are grown at once and separated after harvest) can be successful. Cover cropping – growing a crop which is not taken to harvest but helps protect and feed the soil – will also have the happy effect of capturing sunlight and feeding that energy to the subterranean world, at a time when traditionally the land would have been bare.
5. Bring back grazing animals
This is more than a nod to the permanent pasture analogy, it allows arable farmers to rest their land for one, two or more years and then graze multispecies leys – great in themselves for feeding the soil and for mob-grazed livestock.
Overseeder requires less power – saving fuel
Exhibitors at the 2021 Groundswell event will include JC Machinery, which will showcase the Vredo range of overseeders. The event takes place on 23-24 June at Lannock Manor Farm, Hertfordshire.
The Vredo Agri Twin and Air Series are both renowned for their innovative grassland overseeding, but the addition of the award winning Crop Drill System (CDS) has made it a market first.
Now equipped with the CDS, the machines are able to sow arable crops directly on corn stubble without any tillage at a 15cm row distance, whilst keeping the well-known grass land overseeding features and 96% germination rate.
Because of this, it is the only machine capable of overseeding on grass and arable land, and since the system works through slitting instead of cultivating, less machine power is needed, saving on fuel costs.
The base of the machine remains a pair of slicing disks with an inter-row distance of 7.5cm. But, to sow arable crops deeper, every second pair of discs can be pulled higher using hydraulics, creating a sowing distance of 15cm.
Soil is not disturbed, maintains its strength and keeps the organic matter in the top layer, giving healthier crops using less chemicals and fertilisers.
The seed distributors can quickly be diverted from ten to five exits to work with the pulled-up elements of the Seeder. This works with Vredo’s own pneumatic seed hopper, which can distribute very fine seed – or very large seed – evenly.
The working width of the models ranges from 2.5m to 5.8m, ensuring there is a suitable model for every situation. The multi-functional machine can operate all year round, doesn’t disturb the soil and creates healthier crops while giving more machine hours per unit.
Having the ability to carry out professional grassland and arable land management with one unit makes the new Vredo Agri Air and Agri Twin Series among the most efficient on the market, claims the company.
