Regenerative Agriculture and the Long Repair of India's Soils

On 23 August 2026, the Press Information Bureau issued a research backgrounder titled Rebuilding Farming Systems: Regenerative Agriculture for a Resilient India, gathering a decade of scattered soil-and-sustainability schemes into one frame. Four figures anchor it. Natural farming clusters covered 8.80 lakh hectares and had enrolled 18.19 lakh farmers as of March 2026. About 109 lakh hectares had come under Per Drop More Crop as of May 2026. 25.89 crore Soil Health Cards have been generated since inception. And Indian agriculture and allied sectors recorded decadal growth of 4.45% across FY16-FY25 — the highest of any recent decade.

That last number is the interesting one, because it is the reason the other three exist. India's farm output has been rising. What has been falling, underneath it, is the biological capital that produced the rise.

Growth on a thinning base

Soil organic carbon (SOC) is the variable most other soil properties hang off — water-holding capacity, aggregate stability, cation exchange capacity, and the microbial biomass that mineralises nutrients into plant-available form. It is also the variable that has been quietly draining out of Indian fields.

The National Rainfed Area Authority has estimated that SOC in Indian soils fell from roughly 1% to about 0.3% over 70 years. ICAR and the National Bureau of Soil Survey and Land Use Planning place the working range for Indian soils at 0.3% to 0.6%, against the 1% to 6% found in healthy soils generally. An ICAR-coordinated assessment covering 2017 to 2023, built on 254,236 soil samples drawn from 620 districts, found organic carbon declining across large parts of the country. Close to 30% of India's geographical area carries some form of land degradation.

The mechanism is not mysterious. Every ploughing shatters soil aggregates and exposes organic matter that was physically shielded inside them; oxygen reaches it, microbes oxidise it, and the carbon leaves as CO₂. Residue burning removes the rest. Nitrogen applied without matching carbon accelerates the breakdown of what remains. Meanwhile the soil that loses carbon also loses structure, so it holds less rain, drains worse, and needs more irrigation and more fertiliser to deliver the same yield. That is the cost spiral small and marginal farmers describe as "the land has become hard." Soil formation and soil profiles are standard CDS/OTA geography territory, and this is where the syllabus meets the news.

What "regenerative" actually commits to

The backgrounder draws the definitional line cleanly, and examiners love a clean line: sustainable farming aims to maintain existing conditions; regenerative agriculture aims to improve them. It is defined by outcome, not by input rule.

Six principles are listed: minimise soil disturbance, protect the living roots of perennial crops, maintain soil cover, integrate livestock, limit chemical inputs, and enhance biodiversity. Each carries a mechanism worth understanding rather than memorising.

• Minimum tillage / no-till keeps aggregates intact so occluded carbon is not exposed to oxidation. India's largest no-till practice by area is zero-till wheat, drilled directly into standing rice residue — the practice the Happy Seeder was built for, and the one that removes the agronomic excuse for stubble burning in the rice-wheat belt.
• Living roots keep root exudates flowing into the soil year-round. Those exudates are the carbon currency that feeds soil microbes and mycorrhizal fungi; bare fallow starves them.
• Cover cropping grows a crop for the soil rather than the harvest — it blunts raindrop-impact erosion, moderates soil temperature, suppresses weeds and cycles nutrients. Mulching achieves part of the same effect with residues rather than a living crop.
• Crop rotation breaks pest and pathogen cycles, alternates rooting depths so different soil layers are explored, and — when a legume is in the rotation — fixes atmospheric nitrogen biologically instead of buying it.
• Livestock integration closes the nutrient loop: fodder out, manure back.
• Agroforestry adds a perennial root system that reaches moisture and nutrients below the crop rooting zone, drops litter, and buys the farmer a second income stream on a different time-scale from the harvest.

Four words that are not synonyms

This is the highest-yield distinction in the whole topic, and the one most commonly collapsed.

Natural farming is chemical-free agriculture rooted in Indian traditional knowledge, running on on-farm biological preparations — Beejamrit, Jeevamrit, Ghanjeevamrit, Neemastra and Dashparni — made largely from native livestock dung and urine, with botanical pest formulations, traditional seed, mulching, multi-cropping and boundary trees. Organic farming is a compliance category: it tells you what a farmer may not apply, and it can still be input-intensive if those inputs are simply bought in from outside. Regenerative agriculture refuses to be a category at all — it is a claim about what has happened to soil carbon, biodiversity and water retention, which is precisely why no certificate exists for it.

The scheme map, in one table

Two structural points hide in that table. The first is that regenerative agriculture in India has no single mission — it is an umbrella term for at least six instruments run out of the Department of Agriculture and Farmers Welfare, which is why questions on it usually test which scheme does what. The second is that the Soil Health Card is the measurement layer for everything else: without a plot-level baseline on those 12 parameters — nitrogen, phosphorus, potassium and sulphur; zinc, iron, copper, manganese and boron; and pH, electrical conductivity and organic carbon — a farmer has no way of knowing whether any of this is working. These delivery mechanisms sit squarely in the CDS/OTA economy notes on agriculture and rural development.

The transition valley

Here is what a press release will not tell you: switching a high-input irrigated cereal system to a biological one usually costs yield before it repays yield, and the farmer absorbs the gap.

The evidence is genuinely contested, and the honest position is to say so. Trials run by ICAR-IIFSR, Modipuram, on the basmati rice-wheat system found roughly a 59% decline in wheat yield and a 32% decline in basmati rice yield against integrated crop management, and flagged insufficient nitrogen supply from the prescribed biological inputs as a risk to soil sustainability itself. Those findings were compiled in a 2024 ICRIER-NABARD study. Pointing the other way, assessments in Andhra Pradesh — where Andhra Pradesh Community Managed Natural Farming (APCNF) had drawn in over 1.29 million farmers across 8,168 villages by October 2025 — report stable or improved yields and sharply higher net incomes, driven largely by collapsed input costs.

Both can be true, because they are not measuring the same thing. What is established is that pulling synthetic nitrogen out of an intensively irrigated cereal system opens a yield gap that biological inputs do not close in the first season or two. What is disputed is how deep that gap is, how long it lasts, whether it closes as soil biology recovers, and whether lower input costs and price premiums make the farmer better off even if the tonnage does not fully recover. Rainfed, low-input, diversified systems — the RAD constituency — plainly have the easier transition; the irrigated Green Revolution belt has the hardest one.

The cautionary case is Sri Lanka, which banned imports of synthetic fertiliser and pesticide in 2021. The rice harvest fell by more than 30% within 6 months, tea output fell around 18%, and the ban was reversed in November 2021. The lesson is not that agroecology fails; it is that a nationwide switch compressed into a single season is not a transition, it is a shock. Read that way, NMNF's ₹4,000 per acre per year for 2 years is best understood not as a reward but as a transition subsidy — money to survive the dip — and the Bio-input Resource Centres and Community Resource Persons as the knowledge infrastructure without which the money is wasted.

Where the carbon goes, and whether it stays

Soil is the second-largest terrestrial carbon pool after the oceans, which is why the "4 per 1000" initiative, launched by France at COP21 on 1 December 2015, proposed raising global soil carbon stocks by 0.4% a year as a climate lever.

Two caveats belong with every soil-carbon claim. Saturation: a given soil under a given climate approaches an equilibrium carbon level, so the annual gain slows and eventually stops. Reversibility: one deep ploughing can release years of accumulation, which makes permanence the hard problem for agricultural carbon credits — and it is worth noting that the agroforestry component under PM-RKVY explicitly funds the formulation of projects for the voluntary carbon market. On agroforestry, one first is worth carrying: India was the first country in the world to adopt a National Agroforestry Policy, launched in February 2014 at the World Agroforestry Congress. The government maps the whole effort to SDG 13 (Climate Action), specifically Target 13.1 on strengthening resilience and adaptive capacity to climate-related hazards.

🔑 Revision block

The document. 23 August 2026 · PIB research backgrounder, Rebuilding Farming Systems: Regenerative Agriculture for a Resilient India · consolidates the schemes of the Department of Agriculture and Farmers Welfare.

The definition that gets tested. Sustainable = maintain → Regenerative = improve. Six principles: minimum soil disturbance · living roots · soil cover · livestock integration · limited chemical inputs · biodiversity.

Four words, four different things. Organic = an input standard (NPOP for export, PGS-India for domestic) · Natural farming = a method using Beejamrit, Jeevamrit, Ghanjeevamrit, Neemastra, Dashparni · Regenerative = an outcome claim, uncertified · Sustainable = intent to hold the line.

Scheme → year → instrument. NMNF 2024, ₹4,000/acre/year for 2 years · PKVY 2015, ₹31,500/hectare over 3 years · PDMC 2015-16, 55%/45% micro-irrigation subsidy · RAD 2014-15, ₹30,000/family on 20-hectare IFS clusters · SHC 19 February 2015, 12 parameters every 2 years · Agroforestry moved from SMAF into PM-RKVY in 2023-24.

Figures to carry. 8.80 lakh hectares and 18.19 lakh farmers under natural farming · 18,786 clusters · 109 lakh hectares under PDMC with ₹26,325 crore released · 25.89 crore Soil Health Cards · farm-sector decadal growth 4.45% across FY16-FY25 · SOC down from about 1% to 0.3% in 70 years.

The trap. "Organic" ≠ "natural" ≠ "regenerative"; and the Soil Health Card assesses 12 parameters, not 6 or 10, and is reissued every 2 years, not annually.

The two-sided line, for essay and GD. ICAR-IIFSR trials showed 59% and 32% yield declines in wheat and basmati rice; APCNF's 1.29 million farmers report stable yields and higher net incomes → the disagreement is about the depth and duration of the transition dip, not about whether soil carbon matters. Sri Lanka 2021 is the reminder that speed, not direction, is what breaks a transition.

📋 How this gets asked (PYQ pattern)

Agriculture questions in CDS and NDA general-knowledge papers cluster in three recognisable shapes, and this backgrounder feeds all three.

The scheme-matching shape is the most frequent: a scheme name paired with a year, a ministry, or a benefit figure, and one of the four pairings is wrong. Natural-farming and organic-farming schemes are especially prone to being swapped, because PKVY (2015) and NMNF (2024) sound adjacent and are not — one is an organic-certification pathway, the other a chemical-free method mission. Fix launch year, benefit amount and implementing department for each of the six schemes in the table above and this shape becomes free marks.

The soil-science shape draws on the static syllabus: soil profiles and horizons, soil types of India and their organic-carbon status, nitrogen fixation, the role of legumes, and what green manuring, mulching and cover cropping each do. Anything involving nitrogen fixation, nitrification and the nutrient cycles overlaps directly with the general science notes, so revise the two together rather than separately.

The environment-and-climate shape asks about carbon sinks, the SDGs, and the difference between mitigation and adaptation — and here regenerative agriculture is unusual because it is both, which is exactly the kind of nuance a statement-based question exploits. The fresh hook this cycle is the vocabulary itself: "regenerative agriculture" has now appeared in an official government document with a stated definition and a stated contrast against sustainable farming, so a definitional statement question on that contrast is a live possibility. Keep tracking releases like this through the CDS/OTA current affairs notes, because official definitions are what statement questions are built from. Avoid inventing precision about past papers — what is reliable is the shape of the question, not a specific question number.

If you are preparing for CDS or OTA, the useful habit is to read one backgrounder like this a week and reduce it to a scheme table and six figures — nothing more. Our daily CDS/OTA current affairs posts do exactly that reduction for you, and if you would rather work through the agriculture, environment and economy syllabus with a teacher checking your notes, the upcoming Cavalier Delhi batches run the same material in class.
