Zero Budget Natural Farming: Prospects, Challenges and Concerns (UPSC Economy)
UPSC guide to Zero Budget Natural Farming (ZBNF): Subhash Palekar model, four pillars, benefits, criticisms, and 2024-26 policy on natural farming.
The Economic Survey 2018-19 made a strong case for adopting Zero Budget Natural Farming (ZBNF) as a pathway to doubling farmers’ income by reducing input costs and restoring soil health. The idea has since become mainstream, with the National Mission on Natural Farming (NMNF) approved in November 2024 as a standalone scheme. Yet ZBNF remains deeply contested among scientists who question its scientific basis and yield claims.
Background: The Basic Premise and Four Pillars of ZBNF
Developed by Subhash Palekar (Padma Shri recipient), ZBNF focuses on farming without credit ("Zero Budget") and farming with Nature without chemicals ("Natural Farming"). Its core premise: soil contains all essential nutrients and microorganisms can make them available to plants. It rejects chemical fertilisers, synthetic pesticides, and externally purchased inputs.
The Four Pillars of ZBNF
Jivamrita / Jeevamrutha: A fermented microbial culture made from cow dung, cow urine, jaggery, pulse flour, water, and a handful of soil. Acts as a bio-stimulant promoting microbial activity and nutrient cycling.
Bijamrita / Beejamrutha: Seed treatment using cow dung, cow urine, lime, and soil to protect young roots from seed and soil-borne diseases.
Aachhadana (Mulching): Covering the topsoil with crop residues and organic material to conserve moisture, moderate temperature, and feed soil organisms.
Waaphasa (Moisture): Maintaining the right air-moisture balance in the soil rather than over-irrigating. ZBNF emphasises less water, more aeration.
Supplementary pillars include intercropping, rainwater harvesting, soil revival via earthworms, and use of indigenous seeds.
Government Initiatives to Promote ZBNF / Natural Farming
Under RKVY-RAFTAAR and Paramparagat Krishi Vikas Yojana (PKVY), states were allowed to use funds to promote ZBNF. Andhra Pradesh pioneered the model with its Community Managed Natural Farming (APCNF) programme, targeting 6 million farmers. Himachal Pradesh runs the Prakritik Kheti Khushhal Kisan Yojana.
The NMNF, approved in November 2024 with an outlay of Rs 2,481 crore, seeks to cover 1 crore farmers on 7.5 lakh hectares across 15,000 clusters in two years.
Benefits of ZBNF
- Reduces input costs responsible for present agrarian distress and credit dependence.
- Reduces water consumption by up to 85% in some claims.
- Enhances soil fertility, biodiversity, and microbial health.
- Diversifies income through intercropping, livestock, and non-farm activities.
- Reduces chemical residues in food, addressing public health concerns.
- Climate resilience: Better drought and pest resistance over the long run.
- Long-term income gains for farmers as yields stabilise.
Challenges and Concerns
A panel of agricultural experts from the National Academy of Agricultural Sciences (NAAS) and ICAR have raised the following concerns:
Lack of peer-reviewed scientific studies to validate yield claims. Few independent multi-location trials exist.
Unscientific premise: The claim that soil contains all nutrients is not universally true. Indian soils suffer from widespread deficiencies in nitrogen, phosphorus, zinc, sulphur, and organic carbon.
One-size-fits-all: Indian soils vary from acidic to saline to degraded; ZBNF cannot be applied identically everywhere.
Flawed nutrient physiology: ZBNF's claim that plants get 98.5% of nutrients from air is scientifically incorrect. Plants absorb macro- and micronutrients through root systems, supplemented by minimal foliar uptake.
Not truly "Zero Budget": Inputs like seeds, labour, cattle fodder, and mulching biomass involve real and imputed costs. Family labour is rarely valued.
Yield risks: Experts warn that wholesale replacement of conventional farming with ZBNF could decrease crop production by up to 30-50%, threatening food security.
Scalability concerns: Demands intensive labour and local cow-based inputs — difficult in landless or low-livestock regions.
Way Forward
- Conduct multi-location, multi-season independent trials across agro-climatic zones.
- Develop a science-based package of practices incorporating best elements of natural farming with modern agronomy.
- Follow a phased, voluntary, evidence-based rollout rather than mass replacement.
- Strengthen extension support through KVKs, FPOs, and agricultural universities.
- Build Participatory Guarantee System (PGS) India and Jaivik Bharat certification for market linkages.
Key Schemes and Institutions
| Scheme / Institution | Role |

| National Mission on Natural Farming (NMNF) | Standalone mission from 2024 |
| Paramparagat Krishi Vikas Yojana (PKVY) | Organic farming support |
| RKVY-RAFTAAR | Umbrella agri-scheme |
| Mission Organic Value Chain Development for NE Region (MOVCDNER) | North East focus |
| APCNF (Andhra Pradesh) | Largest community-based natural farming programme |
Latest Developments (2024-26)
Updated context: The Union Cabinet approved the National Mission on Natural Farming (NMNF) in November 2024 with an outlay of Rs 2,481 crore (Rs 1,584 crore Central share). The mission aims to cover 1 crore farmers and bring 7.5 lakh hectares under natural farming in two years, creating 10,000 bio-input resource centres (BRCs) and 2,000 model demonstration farms.
The Union Budget 2025-26 continued support for natural farming while announcing a parallel Mission for Aatmanirbharta in Oilseeds and Pulses to address productivity gaps. The Ministry of Agriculture released standardised protocols for PGS-India certification and a pan-India Natural Farming Portal for farmer enrolment, traceability, and market linkages.
Critics continue to caution against overselling ZBNF. The Niti Aayog and ICAR have emphasised that natural farming should be promoted alongside, not instead of, science-based agronomy, and that safeguards are needed against sudden yield drops in staple crop regions.
UPSC Relevance
GS Paper III topics directly connected: major crops and cropping patterns; issues related to agriculture and allied sectors; agricultural subsidies; economics of animal-rearing and soil health.
Possible questions:
- Critically evaluate the scientific basis and policy feasibility of Zero Budget Natural Farming in India.
- Discuss the role of natural farming in achieving climate-resilient and sustainable agriculture.
- Examine the National Mission on Natural Farming. How does it differ from earlier organic farming schemes?
Essay and interview angles include agrarian distress, ecology vs food security, Gandhian economics of self-reliance, and global organic markets. Aspirants should remember NMNF outlay, APCNF scale, and the key NAAS critique.
