Regenerative Agriculture
Stop ploughing, keep the soil covered, keep something living in it. Not a miracle, and not nothing. The honest version is better than the hype.
The effect compounds within years. Put it in place and it keeps working.
Project Drawdown classifies this as Gradual.
Origins
The Dust Bowl is the origin story, and it is worth remembering that it was not a natural disaster.
In the 1930s, the topsoil of the American plains lifted into the sky and blew east, darkening the sky over Chicago and dusting the desks of Washington. It happened because the deep-rooted prairie sod had been ploughed out and replaced with annual wheat, and when the drought came there was nothing holding the ground down. Hugh Hammond Bennett, testifying to Congress as the dust from Oklahoma literally arrived over the Capitol, got the Soil Conservation Service founded. It is one of the few times in history that an ecological argument has been won by the weather showing up in the room.
What followed was the slow rediscovery of things farmers had known and mechanisation had made unfashionable: cover crops, contour ploughing, crop rotation, keeping something growing in the ground. Then the war came, and with it cheap nitrogen fertiliser made from the same process that had made explosives, and much of it was forgotten again.
The current wave began with people outside the academy. Farmers — Gabe Brown in North Dakota, others like him — who stopped ploughing, mostly out of desperation after successive crop failures, and found after a decade that their soil had changed: darker, spongier, holding water, requiring less input. The soil scientists arrived afterwards to explain it, and are still arguing about how much of the carbon claim holds up.
Both things are true: the farmers are right that the soil got better, and the scientists are right to be cautious about how much carbon it stores. Sorting out which claim is which is the whole job of this page.
What it actually is
Regenerative agriculture is not one practice. It is a bundle, and the bundle has a logic: keep the soil covered, keep the roots living, stop turning it over, and put diversity back.
No-till or reduced till. Ploughing shatters soil structure, exposes organic matter to oxygen, and destroys the fungal networks that hold everything together. It also causes most of the erosion.
Cover crops. Bare soil between cash crops is soil that is eroding, baking, and feeding nothing. A cover crop keeps living roots in the ground year-round, feeding soil biology through the off-season.
Diverse rotations. Monoculture strips the soil of specific nutrients and invites specific pests. Rotation breaks both cycles.
Integrating livestock. Grazed cover crops return nutrients, and animals and plants managed together are closer to how a grassland actually works.
The results that are least disputed are the ones about soil, not carbon: better water infiltration, less erosion, reduced fertiliser and fuel costs, and greater resilience in a drought or a deluge. In an era of increasingly violent weather, that resilience may be worth more than the carbon.
The carbon claim is real but far more contested than the enthusiasm implies, and we are going to say so plainly, because this is the part where the movement has damaged its own credibility.
The numbers
What is solid. The soil benefits are well documented and largely uncontested: better water infiltration, sharply reduced erosion, lower fuel and fertiliser costs, improved drought resilience. Farmers who make the transition frequently report better margins after the establishment years, because they are buying less.
What is contested. The carbon claim. Drawdown’s current assessment of regenerative annual cropping puts it at roughly 14.5 Gt CO₂-eq cumulative under one scenario — a real and meaningful number, and one that sits far below what popular advocacy frequently implies. The gap between the science and the marketing on this is wide.
Why the caution is warranted. Soil carbon is genuinely difficult to measure; it varies enormously by depth, soil type and climate. Some early no-till studies measured only the top layer and reported gains that partly disappeared when deeper cores were taken, because tillage moves carbon down as well as releasing it. Soil carbon also saturates: a soil can only hold so much, and gains slow and stop. And it is reversible — one pass with a plough can release years of accumulation.
The honest position. Regenerative practices reliably improve soil, water, resilience and often profitability. They also sequester carbon, in amounts that are real, meaningful, slower and smaller than the loudest advocates claim, and that can be undone. All of that is worth doing. None of it justifies overselling.
Why it matters
Every farmer knows the smell of good soil, and nobody has ever needed a carbon market to explain to them why it matters.
It is dark, and it crumbles, and it smells faintly sweet, and if you dig into it there are worms. Every generation of farmers before the war knew what that meant and knew that they were meant to hand the ground on with more of it than they found. The word for that was not sustainability. It was husbandry, and it meant something closer to duty.
Somewhere in the second half of the twentieth century, we replaced that idea with a chemistry set. You could buy the nitrogen. You could buy the phosphorus. Soil became a substrate you propped plants up in, rather than a living thing you were the custodian of, and the fact that it was steadily dying was invisible in the yield figures, because the yields kept going up.
Now the soil organic matter maps of the great agricultural regions all point the same direction, downward, and the topsoil of the American Midwest is measurably thinner than it was when it was broken. Some of it is in the Gulf of Mexico.
This is the solution that reaches people who do not care about the climate at all, and it reaches them because it was never really about the climate. It is about handing on a farm in better shape than you got it, which is what every decent farmer has wanted to do since farming began, and which they were, for fifty years, quietly prevented from doing by an economics that paid them not to.
Your grandfather knew what good soil smelled like. That knowledge is not nostalgia. It is a measurement instrument, and it was right.
What it actually takes
Surviving the transition years, which is the whole problem. Yields frequently dip for three to five years as the system re-learns how to work without the inputs it was leaning on. A farmer with a mortgage and an operating loan cannot easily absorb three bad years to reach a better tenth one. This, not scepticism, is why adoption is slow. It is a cash-flow problem and it has a cash-flow solution.
Knowledge, which is genuinely hard-won. Regenerative agriculture is more management-intensive, not less. It requires reading your own soil, adapting to your own climate, and making judgement calls that a bag of fertiliser used to make for you. It is a skill, learned mostly farmer-to-farmer, and the extension services are decades behind.
Not overselling the carbon. This one is on the movement, and it matters. Every inflated soil-carbon claim that collapses under measurement damages the credibility of the practices that genuinely work. The soil, water and resilience case is strong enough on its own. It does not need help.
Fixing the subsidy. Most agricultural support in most wealthy countries pays for yield and acreage, not for soil. A farmer following the incentives is doing exactly what we are paying them to do. Changing the behaviour means changing the payment, and everything else is lecturing.
Where it matters most
The Corn Belt is the epicentre: the most productive farmland on Earth, sitting on soil that is measurably thinner than it was a century ago, much of which is now in the Mississippi and the Gulf.
The Great Plains is where the Dust Bowl happened and where the water is running out. The Ogallala aquifer is being drawn down, and soil that holds more water is not an environmental luxury there; it is the difference between farming and not.
The Pampas of Argentina and the Brazilian Cerrado are where no-till was adopted earliest and most widely, and where the practice has been tested at genuine scale for decades.
The Blackland Prairie and the Ohio Valley are where the transition is happening farmer-by-farmer, largely through peer networks rather than institutions.
The Sahel deserves a mention because it is the largest success nobody talks about: farmer-managed natural regeneration has greened millions of hectares by protecting the trees that resprout in fields, at almost no cost, entirely farmer-led.
How to tell it’s being done well
Are they measuring soil carbon at depth, over years? Surface-only measurement is the oldest trick in this field, and it flatters no-till in particular. Depth-adjusted, multi-year, or it is a claim rather than a finding.
Are they claiming the soil benefits or the carbon miracle? A serious practitioner leads with water infiltration, erosion, resilience and input costs, and treats carbon as a bonus with error bars. An operation leading with gigatons is selling.
Is the whole bundle in place, or just no-till? No-till alone, with the same monoculture and the same chemicals, delivers a fraction of the benefit and is sometimes worse. Cover crops, rotation and living roots are what make the system work.
Are they still ploughing occasionally? Many no-till operations plough every few years for weed control, and one pass can release years of accumulation. This is rarely mentioned and it materially changes the carbon accounting.
Did anyone ask the farmer about year three? If a programme has no answer for the transition dip, it has no answer for the actual barrier.
What you can do
Anyone
- Regenerative is an unregulated word. There is no legal definition and no required audit. Ask what practices, and ask who verified them.
- Buy from farms, not from labels, where you can. The relationship is the certification.
Farmers
- Start with one field, not the whole farm. Learn on ground you can afford to have a bad year on.
- Cover crops and living roots deliver the fastest visible return: water infiltration you can watch in a rainstorm.
- Find a farmer who is three years ahead of you. This knowledge moves farmer-to-farmer far better than it moves through institutions.
- Plan for the transition dip. It is real, it is temporary, and it is what stops most people.
Policymakers
- Pay for the transition years. This is the barrier. Everything else is commentary.
- Pay for outcomes, not practices: soil carbon, water infiltration, erosion. Practices can be gamed; measured soil cannot.
- Stop paying for yield alone. Farmers are following the incentives we set.
Business and investors
- If you make regenerative claims, verify them at depth and over years, or do not make them. Collapsing soil-carbon claims are becoming a genuine liability.
- Fund the transition. It is a three-to-five year cash-flow gap with a strong balance sheet on the far side, which is precisely what finance exists to bridge.

Questions
What actually is regenerative agriculture?
Not a single practice but a bundle: minimal tillage, keeping the soil covered with cover crops, keeping living roots in the ground year-round, diverse rotations, and often integrating livestock. The logic is to treat soil as a living system rather than a substrate.
Does it really sequester carbon?
Yes, but less than the loudest advocates claim, and it is reversible. Soil carbon is hard to measure, varies with depth and soil type, saturates over time, and can be released by a single pass of the plough. Project Drawdown's assessment of regenerative annual cropping is meaningful but well below what popular advocacy often implies. The honest position is that the carbon is real, slower and smaller than advertised, and undoable.
So is it worth doing?
Emphatically, yes, and the reasons are stronger than the carbon. The soil benefits are well documented and largely uncontested: better water infiltration, sharply reduced erosion, lower fuel and fertiliser costs, and much better resilience in drought and flood. In an era of violent weather, that resilience may be worth more than the carbon ever was.
Why don't more farmers do it?
Because yields frequently dip for three to five years during the transition while the system learns to work without the inputs it was leaning on. A farmer with an operating loan cannot easily absorb three bad years to reach a better tenth one. This is a cash-flow problem, not a knowledge or motivation problem, and it has a cash-flow solution.
Is no-till enough on its own?
No. No-till with the same monoculture and the same chemical regime delivers a fraction of the benefit and can in some circumstances be worse. The cover crops, the rotation and the living roots are what make the system function. And many no-till operations still plough every few years for weed control, which can release years of accumulated carbon in a single pass.
Is regenerative a regulated term?
No. There is no legal definition and no required audit, which means the word appears on products with wildly varying justification. Ask which practices, over what period, verified by whom. A serious operation will answer instantly.
