For Agrii agronomist John Vickery the first question to consider before moving to a new system is to define your objective. “What is it you want to achieve?”, he asks. The outcome, not the process, should take priority.
The term ‘regenerative agriculture’ has become the latest buzz phrase to sweep through farming. To some, it is a new approach that points to a future where synthetic pesticides and manufactured fertilisers are replaced with a culture of friendly bacteria working in harmony with Mother Nature.
To others, it’s a just a trendy way of describing a system that has been practiced since man began tilling the land, ‘mixed farming’ where livestock and a broad rotation support a functional and resilient soil.
A path to a sustainable future?
Whichever camp you fall into, the principles that support regenerative agriculture represent a path to a more sustainable future. One that reflects the financial, regulatory, and climatic pressures facing the sector without compromising profitability.
Few would object to a future with less reliance on synthetic chemistry or inorganic fertilisers but journeying to this farming nirvana is not without its considerations and compromises.
How to achieve change or sustain it is often the focus of debate.
Less intensive approach
“Many systems, be it regenerative agriculture or something else, offer the promise of a less intensive approach without a material impact on profitability. Where this is practiced successfully, we see significant savings are made from fixed costs through lower establishment and labour expenses,” says Mr. Vickery.
“While the desire to create a more functional soil and reduce production costs may be the short-terms driver, the need to adapt systems to fit future environmental schemes and regulations should also be considered.
Systems and schemes (pic grazing sheep)
“It is clear from proposals outlined by DEFRA that schemes that succeed the CAP will focus on environmental delivery. We see the principles of regenerative agriculture as closely aligned with much of what is proposed in the Environmental Land Management Scheme (ELMS), for example,” says Mr. Vickery.
For Mr. Vickery, there are five main points to consider:
Crop diversity. A range of combinable crops should be complemented by forage and cover crops to protect soils and support livestock grazing.
Minimal soil movement. Moving to no-till is not without its challenges, but one of the biggest lessons from those who have succeeded is to avoid travelling on ground when conditions aren’t favourable.
Flexible rotations. Where and what is grown is often influenced by weather, having the flexibility to adapt to conditions supports a dynamic enterprise.
Year-round soil cover. Cover crops come in many forms. With a little ingenuity they can be adapted to provide both ground cover and a source of forage. On a Cotswold farm, Agrii has worked with one adopter to implement a two-year fodder beet and Westerwolds ryegrass break to provide winter grazing; but there are many other examples.
An integrated livestock enterprise. The synergies between crops and livestock support the sustainability of many farming businesses, especially those with land of marginal production value. These credentials will become increasingly important under ELMS.
“The re-birth of regenerative agriculture, which is not a new concept, owes much to the expanded focus placed on soil. This is especially important in the era of climate change where the role of soils in sequestering carbon is becoming a focus of policymakers,” he explains.
Case study – Heavy land transition (pic Tom Martin)
For arable and sheep farmer Tom Martin who has spent the past three years transitioning his heavy land farm west of Peterborough to a regenerative system, it’s about understanding the details.
“These are not new techniques but are perhaps being applied with greater understanding of the benefits they offer. It’s a more holistic approach than we practiced in the past,” says Mr Martin.
His efforts are being rewarded and perhaps most importantly, yields have been maintained.
“We’re three years into this change and our output levels have been maintained. That is not to say, we have completely abandoned tillage as there are times you have to farm what’s in front of you,” says Mr. Martin.
Having moved through what many might consider ‘phase 1’, his attention has turned to identifying where further costs can be stripped out.
“Our focus for the past three years has been on improving soil biology and building carbon in the form of organic matter while broadening the rotation. We have seen the benefits through reduced surface run-off during wet weather, for example,” he says.
“The next stage is to review our input practices. This year we have made more of an attempt to target fungicide use more closely,” he adds.
Attitude is all
Whichever system or elements of a system a grower is seeking to incorporate into their existing practice, both John Vickery and Tom Martin agree that attitude is the foundation of success.
“From a financial perspective, there are some obvious wins. Savings in fuel costs from less intensive cultivations soon add up as does reduced herbicide use from less soil disturbance,” says Mr Vickery.
“Think carefully about how and why you are doing what you do. Every journey across a field should be questioned with recreational tillage avoided at all costs,” he adds.
Mr Martin is a little more direct about what makes a difference.
“Appreciate that it’s the individual that makes the difference. It’s the person who is responsible for the big decisions that matters. You can either mess things up or be the architect of success. It’s a personal choice,” he says.
