Historical Evolution and Paradigm Shift in Indian Agriculture
Indian agriculture has undergone a massive transformation from traditional, low-external-input sustenance farming to high-input intensive chemical farming during the Green Revolution era (mid-1960s). While the introduction of high-yielding dwarf varieties of wheat (Triticum aestivum) and rice (Oryza sativa) along with synthetic fertilizers and chemical pesticides made India self-sufficient in food grain production, subsequent decades revealed severe ecological and agronomic repercussions.
- Second-Generation Problems: Intensive chemical cultivation led to multi-nutrient deficiencies (especially sulfur, zinc, and boron), declining organic carbon levels in soils (often dropping below 0.3%), groundwater depletion, and pesticide residue accumulation in the food chain.
- Rise of Alternative Farming: To counteract environmental degradation, soil health deterioration, and escalating input costs, modern agrarian science has redirected focus toward Natural Farming (Prakritik Krishi) and Certified Organic Farming. These systems harness ecological loops, biological nitrogen fixation, and indigenous microorganisms (IMOs).
Core Principles and Conceptual Framework of Organic Farming
Organic farming is a holistic production management system that promotes and enhances agro-ecosystem health, including biodiversity, biological cycles, and soil biological activity. It is governed by four overarching principles defined by the International Federation of Organic Agriculture Movements (IFOAM):
- Principle of Health: Sustaining and enhancing the health of soil, plant, animal, human, and planet as one indivisible whole. Healthy soils produce healthy crops that foster health in animals and humans.
- Principle of Ecology: Basing agricultural systems on living ecological systems and cycles, working with them, mimicking them, and helping to sustain them.
- Principle of Fairness: Building relationships that ensure equity with regard to the common environment and life opportunities, providing a good quality of life and food sovereignty.
- Principle of Care: Managing agriculture in a precautionary and responsible manner to protect the health and well-being of current and future generations and the environment.
Natural Farming Systems: Zero Budget Natural Farming (ZBNF) / Subhash Palekar Natural Farming (SPNF)
Natural farming, popularly popularized in India as Subhash Palekar Natural Farming (SPNF) and previously known as Zero Budget Natural Farming, operates on the foundational premise of eliminating chemical inputs and credit-based external purchases. It relies exclusively on indigenous on-farm biological inputs.
- Jeevamrutha: A fermented microbial culture made from cow dung, cow urine, jaggery, pulse flour, live soil, and water. It acts as a catalytic inoculant that revives dormant soil macro- and micro-organisms.
- Bijamrutha: A seed-treatment formulation utilizing cow dung, cow urine, lime, and forest soil to protect germinating seeds from soil- and seed-borne fungal pathogens such as Fusarium oxysporum and Rhizoctonia solani.
- Acchadana (Mulching): Soil mulching using crop residues, live cover crops, or dead organic matter to conserve soil moisture, suppress weed emergence, and regulate soil thermal regimes.
- Whapasa: Maintaining the optimal balance of air molecules and water vapor molecules within the root zone to prevent root asphyxiation and enhance moisture retention.
Agronomic Management, Nutrient Cycling, and Plant Protection
Managing soil fertility and crop protection in organic and natural systems requires proactive, preventive, and systemic approaches rather than curative chemical applications.
- Biological Nutrient Supply: Utilization of farmyard manure (FYM), vermicompost, green manure crops like sunnhemp (Crotalaria juncea) and dhaincha (Sesbania aculeata), and biofertilizers such as Rhizobium, Azotobacter, Azospirillum, and Phosphorus Solubilizing Bacteria (PSB) like Bacillus megaterium.
- Integrated Pest Management (IPM) & Biopesticides: Deployment of botanical extracts (neem oil containing azadirachtin), entomopathogenic fungi (Beauveria bassiana, Metarhizobium anisopliae), and bacterial bio-agents like Bacillus thuringiensis (Bt) to suppress lepidopteran pests like Helicoverpa armigera.
- Weed Management: Hand weeding, mechanical hoeing, stale seedbed techniques, competitive intercropping, and allelopathic cover crops instead of synthetic herbicides like glyphosate or pendimethalin.
National Schemes, Certification, and Economic Scope in India
The institutional scope of organic and natural farming in India is backed by robust national policies, certification frameworks, and market mechanisms.
- PKVY (Paramparagat Krishi Vikas Yojana): Promotes organic farming through cluster-based approaches, participatory guarantee systems (PGS), and financial assistance for input procurement and marketing.
- NMOOP / Mission Organic Value Chain Development for North Eastern Region (MOVCDNER): Focuses on developing end-to-end organic value chains, processing, branding, and export facilitation.
- Certification Systems: Third-party certification (e.g., NPOP - National Programme for Organic Production) for export markets and Participatory Guarantee Systems (PGS-India) for domestic markets through peer-review mechanisms.
| Parameter / Feature | Conventional Chemical Farming | Certified Organic Farming | Natural Farming (SPNF) |
|---|---|---|---|
| External Input Dependency | Very high (synthetic fertilizers, chemical pesticides) | Medium (permitted organic inputs, biofertilizers, compost) | Zero external input (completely self-sustaining on-farm) |
| Soil Fertility Concept | Feeding the plant directly via soluble inorganic ions | Feeding the soil organic matter and microbiological web | Reviving native soil microbes via microbial inoculants (Jeevamrutha) |
| Certification & Traceability | Not applicable | Mandatory third-party (NPOP) or PGS certification | Peer-reviewed or trust-based local community networks |
| Economic Viability | High variable cost, dependent on market price and credit | High initial transition cost, premium market price realization | Virtually zero input cost, high net returns for smallholders |

- India ranks first globally in terms of organic farmers and ninth in terms of certified organic agricultural land (FiBL & IFOAM statistics).
- Sikkim became the world's first fully organic state in the year 2016.
- Jeevamrutha requires fresh cow dung (approx. 10 kg) and cow urine (5-10 liters) per 200 liters of water for one acre.
- Participatory Guarantee Systems (PGS-India) operates under the Ministry of Agriculture and Farmers Welfare for domestic organic assurance.
- Azadirachtin, the principal active limonoid extracted from neem (Azadirachta indica), acts as an effective antifeedant and growth disruptor in organic pest management.
- Green manure crops like sunnhemp (Crotalaria juncea) accumulate 80-100 kg N/ha within 45-60 days of growth.
- The National Programme for Organic Production (NPOP) standards are officially notified under the Foreign Trade (Development and Regulation) Act by the Ministry of Commerce and Industry.
- Whapasa refers to the coexistence of equal proportions of water molecules and air spaces within soil micro- and macro-pores.
- Confusing Natural Farming with Organic Farming: Organic farming still permits certified commercial organic inputs and mined minerals, whereas Natural Farming (SPNF) strictly prohibits all external inputs, even organic fertilizers bought from outside the farm.
- Assuming organic farming yields drop permanently: While there is a temporary yield reduction during the 2-3 year transition phase, yields stabilize and often surpass conventional systems as soil biological health recovers.
