Zero Budget Natural Farming (ZBNF) & Subhash Palekar
The foundation of ZBNF lies in its response to the deep-seated problems plaguing Indian agriculture today. While government data from 2024-25 shows positive trends in food grain production and increased budget allocations for the sector, the ground reality for many farmers remains difficult.
A significant proportion of farmer households are still grappling with outstanding debt, with one study from the National Bank for Agriculture and Rural Development (NABARD) finding that over half of all agricultural households were indebted in 2021-22.
This is often driven by the escalating costs of fertilizers, pesticides, and high-yield seeds. Furthermore, the ecological costs are becoming unbearable. An estimated 32% of land in India is degraded, with a quarter undergoing desertification, severely impacting soil health and water quality.
These issues are compounded by the unpredictability of climate change, leading to crop losses and heightened farmer distress. ZBNF presents itself as a direct counter-narrative to this crisis, offering a way out of the debt cycle and a path toward environmental restoration.
What is Zero Budget Natural Farming (ZBNF)?
Zero Budget Natural Farming (ZBNF), or Subhash Palekar Natural Farming (SPNF), is a chemical-free, low-input agricultural method that champions working with nature rather than against it.
Its core philosophy is simple yet powerful: by using locally available resources and traditional knowledge, a farmer can eliminate the need for costly external inputs like synthetic fertilizers and pesticides. This eliminates the need for credit, thus making the farming “zero budget.”
The “zero budget” principle is a radical departure from both conventional and many forms of organic farming. While organic farming also avoids chemicals, it often relies on expensive, commercially produced organic manures, vermicompost, and other inputs that can still be costly for small farmers.
ZBNF, in contrast, focuses on creating all necessary inputs on the farm itself, using resources like native cow dung, cow urine, and crop residues, which are considered to have a “zero cost.” By eliminating the need for loans to buy these inputs, ZBNF aims to break the cycle of debt that has trapped so many Indian farmers.
It is a philosophy of self-reliance and ecological harmony, where the farm ecosystem is seen as a self-sustaining entity, much like a natural forest.
Subhash Palekar: The Architect of ZBNF
The ZBNF movement is inseparable from the man who created it, Subhash Palekar. An agricultural scientist and farmer from Maharashtra, Palekar’s journey began not as a proponent of natural farming, but as a dedicated advocate of the Green Revolution.
For over a decade, from 1972, he successfully used modern chemical farming techniques on his family farm. However, by the mid-1980s, Palekar noticed a disturbing trend: his yields began to decline, and the soil was losing its vitality.
This observation, combined with his background as a spiritual thinker and his study of natural forest ecosystems, led him to question the very foundations of chemical agriculture. From 1986 to 1988, he delved into a deep study of how forests thrive without human intervention, identifying the natural processes of nutrient cycling and soil building.
He spent the next seven years rigorously experimenting with these natural principles on his own farm, ultimately developing and refining the ZBNF model in the mid-1990s. In 2016, his pioneering work was recognized with the Padma Shri, India’s fourth-highest civilian award, cementing his legacy as a revolutionary figure in Indian agriculture.
The Four Pillars of ZBNF
Subhash Palekar’s framework for ZBNF rests on four key pillars that form the foundation of a self-sustaining agricultural system. These pillars are based on the belief that everything a plant needs is already present in the soil and atmosphere, and that the role of the farmer is simply to activate these natural processes.
The latest facts and figures show that the effectiveness of these pillars, particularly Jiwamrita and mulching, has been a key reason for the adoption of ZBNF, with farmers reporting improved soil health and better moisture retention.
1. Bijamrita (Seed Treatment)
This is the first step in ZBNF, where seeds are treated with a powerful natural coating to protect them from diseases. Bijamrita is a simple concoction made from the dung and urine of a native cow, water, lime, and a handful of soil.
This preparation acts as a natural fungicide and germination promoter, ensuring that seeds are strong and resistant to soil-borne and seed-borne pathogens from the very beginning. This practice alone can save a farmer a significant amount of money that would otherwise be spent on chemical seed treatments.
2. Jiwamrita (Microbial Fertilizer)
Often described as the heart of ZBNF, Jiwamrita is a fermented microbial culture that breathes life back into the soil. It is a potent mixture of native cow dung, cow urine, jaggery (natural sugar), pulse flour, and uncontaminated soil.
When applied to the farm, this liquid fertilizer acts as a catalyst for a massive proliferation of microorganisms and earthworms, which are crucial for making nutrients available to the plants. It is believed that a small amount of Jiwamrita can revitalize a large area of land, with the principle that one native cow can provide enough dung and urine to support up to 30 acres of land.
3. Mulching (Covering Soil)
Mulching involves covering the topsoil with a layer of organic material, such as crop residues, dry leaves, or other biomass. This is a foundational practice in ZBNF, as it plays a critical role in mimicking a forest floor.
The mulch protects the soil from direct sunlight, conserves soil moisture by preventing evaporation, and suppresses weed growth. As the mulch decomposes, it slowly adds humus to the soil, which is a rich organic matter that further improves soil structure and fertility.
4. Waaphasa (Soil Aeration)
Waaphasa, meaning soil aeration, is the final pillar and represents the ideal state of the soil. It is a condition where the soil has a perfect balance of moisture and air, which is essential for healthy root growth and the activity of microorganisms.
This state is achieved naturally through the combined effects of Jiwamrita and mulching, which improve the soil’s structure and its ability to hold water. Waaphasa is particularly crucial in drought-prone regions, where it helps the soil and crops remain resilient even during dry spells.
How ZBNF Achieves “Zero Budget”
The term “Zero Budget” is the most revolutionary promise of this farming model, and it is achieved through a combination of localization, cost reduction, and enhanced profitability. Recent studies and government reports highlight that ZBNF is successful in significantly reducing farmers’ expenses.
For instance, a 2024-2025 study from the International Journal of Plant & Soil Science noted that ZBNF prioritizes indigenous cows and locally sourced resources, emphasizing cost reduction as a primary benefit for farmers facing financial stress.
The latest NITI Aayog reports have also shown that ZBNF can improve the Benefit-Cost (B:C) ratio for farmers, primarily by slashing input expenses.
1. Resource Localization and Cost Reduction
ZBNF’s primary mechanism for achieving its “zero budget” is the complete elimination of purchased inputs. Farmers are taught to use only what is available on or around their farms. This means no more synthetic fertilizers or pesticides, which constitute a large portion of a farmer’s annual expenses.
A key study in Andhra Pradesh found that ZBNF processes can require 50-60% less water and electricity, further reducing the overall cost of cultivation. By relying on their own seeds and the natural inputs prepared from one native cow, farmers are freed from the cycle of taking loans to buy costly materials every season.
2. Profitability and Debt Reduction
The economic benefits of ZBNF are not just about saving money, but also about making more of it. With significantly lower production costs, a farmer’s net income can increase even if there are some initial yield variations.
Many ZBNF farmers also practice poly-cropping, growing multiple crops simultaneously, which provides a steady income stream and acts as a buffer against crop failure. Furthermore, as consumers become more health-conscious, there is a growing demand for chemical-free produce, allowing ZBNF farmers to command premium prices in the market.
The NITI Aayog’s evaluation of ZBNF initiatives in various states found that farmers in Karnataka and Maharashtra experienced a notable improvement in their Benefit-Cost ratios, with some seeing their profits increase by over 15% due to reduced input costs.
Impact and Adoption of ZBNF
The success of ZBNF is not just a theoretical concept; it is being implemented on a large scale across India, with significant government support and recognition. The latest data indicates that ZBNF and other natural farming practices are rapidly gaining ground.
The Indian government, as of late 2024, has approved a new National Mission on Natural Farming (NMNF) with a substantial outlay, targeting to initiate 1 crore farmers into natural farming practices on 7.5 lakh hectares of land.
1. State-Led Initiatives
Several states have become pioneers in promoting ZBNF. Andhra Pradesh has been a frontrunner, with a massive state-led program that aims to transition all of its 6 million farmers to natural farming by 2027.
Himachal Pradesh, through its “Prakritik Kheti Khushhal Kisan Yojana” launched in 2018, has seen over 1.65 lakh farmers adopt natural farming practices on nearly 20,000 hectares of land, reaching almost all of its village councils.
In Karnataka, where the movement first took hold, around 100,000 farmer families have adopted ZBNF, with many reporting stories of reduced debt and improved soil quality.
2. Global Recognition
The model’s potential has not gone unnoticed on the global stage. The United Nations Environment Programme (UNEP) and the Food and Agriculture Organization (FAO) have highlighted ZBNF as a key model for sustainable agriculture that can help achieve the Sustainable Development Goals (SDGs).
An FAO report specifically mentioned that ZBNF could contribute to nearly a quarter of the 169 SDG targets, particularly those related to poverty reduction, food security, and climate action. This international recognition validates the ZBNF approach as a viable, climate-resilient solution for smallholder farmers worldwide.
Criticisms and Challenges
Despite its impressive growth and success stories, ZBNF is not without its critics and challenges. The debate over its effectiveness is ongoing, with the scientific community and policymakers expressing certain reservations.
1. The Yield Debate
One of the most significant criticisms revolves around crop yields. While proponents claim that ZBNF can lead to long-term yield stability, some studies by institutions like the Indian Council of Agricultural Research (ICAR) and the University of Agricultural Sciences, Dharwad, have shown initial yield reductions in some crops, such as wheat and basmati rice.
A 2024 NITI Aayog report also confirmed that ZBNF yields are often comparable to or slightly lower than conventional methods, especially without the use of supplemental farmyard manure. The consensus is that yields may dip during a transition period of 2-3 years before stabilizing.
2. Scalability and Labor Intensity
The scalability of ZBNF is another major concern. The method’s reliance on dung and urine from native Indian cows raises questions about the availability of enough cows to support a nationwide transition.
Furthermore, the manual preparation of inputs like Jiwamrita and the labor-intensive practice of mulching can be a significant constraint, particularly for large-scale farms that rely on mechanization. Some critics argue that the “zero budget” claim doesn’t account for the increased labor costs and the opportunity cost of the farmer’s time.
3. Scientific Scrutiny
The lack of robust, long-term, peer-reviewed scientific studies is a key criticism. Institutions like the National Academy of Agricultural Sciences (NAAS) have called for more research before ZBNF is promoted on a national scale.
The ICAR has initiated multi-location studies to systematically evaluate the model’s impact on productivity, economics, and soil health. This scientific skepticism highlights the need for more data-driven validation to address concerns about the efficacy and long-term viability of ZBNF across different soil types and climates.
ZBNF vs. Mainstream Agriculture Policies
ZBNF stands in stark contrast to the chemical and GMO-driven approaches that have dominated mainstream agriculture policies for decades.
While the government has traditionally subsidized chemical fertilizers and promoted high-yielding hybrid seeds, there has been a notable shift in recent years to support natural farming. This is evident in the push to promote ZBNF as a core component of sustainable agriculture.
1. Policy Integration
ZBNF has been successfully integrated into national policy. The government’s “Bhartiya Prakritik Krishi Padhati” (BPKP) sub-scheme, a part of the Paramparagat Krishi Vikas Yojana (PKVY), actively promotes ZBNF. Under this scheme, farmers are provided financial assistance of ₹12,200 per hectare over three years to support cluster formation, capacity building, and input production.
This policy push reflects a growing understanding that ZBNF can not only contribute to food security but also to the broader goals of environmental sustainability and farmer empowerment.
2. Alignment with Agroecology
ZBNF aligns perfectly with the principles of agroecology and food sovereignty movements. It emphasizes working with local ecosystems, fostering biodiversity, and reducing dependence on global supply chains.
This aligns with the idea of food sovereignty, which advocates for the right of local communities to define their own food and agriculture systems. ZBNF, by empowering farmers to become self-reliant and produce their own inputs, is a powerful tool for achieving this goal.
Future of ZBNF and Palekar’s Legacy
As India and the world face the increasing pressures of climate change, soil degradation, and economic volatility, the future of ZBNF looks more relevant than ever. The movement is poised to grow through a combination of policy support and grassroots efforts, building on the foundation laid by Subhash Palekar.
Policy Integration: The government’s renewed focus on natural farming through the National Mission on Natural Farming (NMNF) is a powerful signal. With dedicated financial support and a commitment to establish “Bio-input Resource Centres” and “Model Demonstration Farms,” the government is creating the institutional framework needed to scale up ZBNF.
These policies, combined with the successful state-level initiatives, will likely drive a significant increase in the adoption of natural farming across the country.
Grassroots Networks: The ZBNF movement has thrived on a farmer-to-farmer learning model, where experienced practitioners train and mentor new farmers. This grassroots network is a key strength of the movement, ensuring that knowledge is passed down in a practical and accessible way.
This community-led approach builds trust and fosters a sense of collective empowerment, which is crucial for the long-term success and sustainability of the model.
Global Relevance for Climate-Resilient Farming: ZBNF’s focus on soil health, water conservation, and biodiversity makes it a highly climate-resilient farming model. In a world of unpredictable weather patterns, a healthy, humus-rich soil that can retain more water is a farmer’s best defense against drought.
By promoting practices that reduce greenhouse gas emissions and enhance ecosystem services, ZBNF offers a viable and scalable solution for creating more resilient and sustainable food systems globally. Subhash Palekar’s legacy is not just about a farming method; it is about a vision for a self-reliant, poison-free, and compassionate relationship between humans and the earth.
Conclusion
Zero Budget Natural Farming, as envisioned by Subhash Palekar, is more than just an agricultural technique. It is a philosophy that seeks to liberate the small farmer from the chains of debt, dependence, and ecological degradation. By challenging the core tenets of the Green Revolution, ZBNF offers a compelling alternative rooted in traditional wisdom and a deep understanding of natural processes.
While questions about scalability and scientific validation remain, the movement’s growing adoption, backed by both grassroots enthusiasm and government policy, suggests it is a powerful force for change.
It represents a return to self-reliance, a celebration of local resources, and a vision of an agriculture that is not only profitable but also kind to the earth and the people who work it.
