Natural Farming — ZBNF and Subhash Palekar Method

What is Natural Farming?

Natural farming is a philosophy and practice of agriculture that seeks to work in complete harmony with natural processes — using zero or minimal external inputs, avoiding all synthetic chemistry, and mimicking the functioning of natural ecosystems. The core premise: nature has sustained its own fertility for millennia without human intervention; farming can do the same by observing and emulating natural cycles.

Natural farming differs from organic farming in degree of intervention:

• Organic farming: uses approved organic inputs (compost, vermicompost, botanical pesticides)
• Natural farming: aims to eliminate even organic inputs over time; relies on locally available, on-farm biological materials

Zero Budget Natural Farming (ZBNF)

Background

ZBNF was developed by Subhash Palekar, a farmer-scientist from Maharashtra, through decades of on-farm experimentation and observation.

• Padma Shri awardee (2016) — India's fourth highest civilian honour
• Origin: Amravati district, Maharashtra; 1990s
• Philosophy: "Mother Earth is complete in herself; she needs no external inputs"
• "Zero Budget" means: total farming cost approaches zero because all inputs come from the farm itself (especially from a single desi cow)
• ZBNF is built on the insight that soil microorganisms — not chemical fertilizers — feed the plant, and that one desi cow per 30 acres provides all the microbial inoculant needed

The One Cow Principle

• One desi (indigenous) cow (Gir, Sahiwal, Red Sindhi, Tharparkar, Ongole) is sufficient for 30 acres
• One cow produces ~10 kg fresh dung/day + 5–10 L urine/day
• This is the raw material for Beejamrit and Jeevamrit
• Why desi cow?: Desi cows have a distinctive hump (surya ketu nadi) — Palekar claims this concentrates beneficial microbes in their dung; conventional cattle (HF, Jersey) produce different microbial profiles
• Note: The scientific basis of the desi cow specificity is debated; however, the overall ZBNF system has shown practical results

The Four Pillars of ZBNF

Pillar 1: Beejamrit (Seed Treatment)

Purpose: Protect seeds from seed-borne and soil-borne fungal and bacterial infections; replace chemical seed dressings

Recipe (for 100 kg seed):

• 5 litres of water
• 250 g fresh cow dung (desi cow)
• 250 mL cow urine (fresh or aged)
• Handful of soil from the farm bund (contains local soil microbes)
• 1 small piece of lime (chuna) — optional; adjusts pH

Preparation:

1. Mix all ingredients in water; stir well
2. Allow seeds to soak 6–8 hours, or coat seeds and shade-dry
3. Sow treated seeds within 24 hours

Function:

• Cow dung bacteria protect seed from pathogenic fungi
• Soil from bund introduces locally adapted beneficial microflora
• Lime creates slight alkalinity unfavourable to many pathogens
• A low-cost replacement for chemical seed treatments (thiram, captan, imidacloprid)

Pillar 2: Jeevamrit (Soil Inoculant / Microbial Stimulant)

Jeevamrit is the most critical and scientifically interesting element of ZBNF — it functions as a fermented microbial consortium that colonizes the rhizosphere with beneficial microorganisms.

Recipe (for 200 L — sufficient for 1 acre/month):

Ingredient	Quantity	Function
Water	200 L	Carrier
Fresh cow dung	10 kg	Microbial source; bacteria, actinomycetes, fungi
Cow urine (aged)	5–10 L	Antimicrobial against pathogens; micronutrients
Jaggery (gur)	2 kg	Carbon source; food for microbes; promotes fermentation
Pulse flour (besan)	2 kg	Protein; amino acid source for microbial growth
Bund/forest soil	1 handful	Inoculates with locally adapted soil organisms

Preparation:

1. Combine all ingredients in a drum; stir thoroughly
2. Cover loosely (allow gas escape); keep in shade
3. Ferment for 48 hours (in warm conditions, 25–35°C)
4. Stir 2–3 times during fermentation
5. Ready when frothy/bubbly — active fermentation visible

Application:

• 200 L Jeevamrit per acre per month via irrigation channels (pour into running irrigation water) or by spraying on soil
• Do NOT apply in hot sun — apply in morning or evening
• Apply at critical crop growth stages: germination, tillering, flowering, grain filling

Scientific basis: Jeevamrit introduces 300–500 crore (3–5 billion) beneficial microorganisms per mL of fresh cow dung. Fermentation with jaggery and besan amplifies microbial populations exponentially. The result is a microbial inoculant that activates soil biology — effectively replacing chemical fertilizers by mobilizing soil nutrients through microbial action.

Pillar 3: Mulching

Palekar defines three types of mulching, all serving the same core function: protect soil, conserve moisture, feed soil life, suppress weeds.

Type	Description	Example
Soil mulch (Mitti ki mulch)	Shallow tillage (1–2 cm) to create a loose soil dust mulch on surface; breaks capillary channels	Traditional khurpa (hand hoe) in dry regions
Straw mulch (Jeevant mulch — living/dead organic)	Dry crop residues spread on soil surface 3–5 cm thick	Rice straw, wheat straw, dried leaf litter
Living mulch (Jeevan Amrit)	Intercropped low-growing plants that cover soil between main crop rows	Cowpea, clover, creeping legumes

Functions of mulching in ZBNF:

• Maintains Waaphasa (optimal soil air–water balance)
• Prevents soil surface sealing by raindrops
• Feeds soil organisms (earthworms, fungi, bacteria) as mulch decomposes
• Suppresses weed growth — avoids herbicide need
• Moderates extreme soil temperatures

---

Pillar 4: Waaphasa (Soil Aeration and Moisture Balance)

Waaphasa is perhaps the most philosophically distinctive element of ZBNF:

Palekar defines Waaphasa as the state where soil pore space contains both water vapour and air in equal proportion. He argues that:

• Roots do not need liquid water — they absorb water vapour
• Roots need oxygen for aerobic respiration — they require air
• Conventional flood irrigation creates waterlogging → root zone becomes anaerobic → root stress
• The optimal state is moist but not saturated — like a wrung-out sponge

Practice implications:

• Give water in frequent, small doses (irrigation gaps of 7–10 days for most crops)
• Avoid waterlogging entirely
• Maintain mulch to preserve moisture without over-watering
• Deep roots naturally seek this balance if soil is undisturbed

Scientific note: Waaphasa aligns with modern understanding of soil water potential and aerobic root respiration, though framed in non-technical terms by Palekar.

Andhra Pradesh ZBNF Scaling — The World's Largest Natural Farming Programme

• RySS (Rythu Sadhikara Samstha): state agency of Andhra Pradesh government
• Scale: scaled ZBNF to 700,000+ farmers by 2019; target of 6 million farmers by 2024
• Investment: ₹2,000+ crore by AP state government
• Training: 45-lakh farmer training programmes; farmer-to-farmer cascade learning
• Outcomes documented: reduced input costs (avg ₹4,000–8,000/acre savings); comparable yields after transition
• AP significance: largest government-backed natural farming initiative in the world; influenced NITI Aayog national policy

Other Natural Farming Philosophies

Fukuoka Method (Japan)

• Masanobu Fukuoka (1913–2008); "One Straw Revolution" (1975)
• Four principles: no tillage, no fertilizer, no pesticide, no weeding
• Clay seed balls (tsuchi dango): seeds encased in clay + compost balls; rolled into fields; germinate when conditions right
• Philosophy: human intervention disrupts natural balance; "do nothing" is the highest farming practice
• Requires deep understanding of local ecology; not easily scalable

Biodynamic Farming (Rudolf Steiner)

• Founded 1924; lectures to farmers in Koberwitz, Germany
• Views farm as a self-contained living organism
• Preparations 500–508: specific materials (cow dung in cow horn, medicinal herbs) dynamized (stirred in alternating vortices)
• Cosmic calendar: planting, weeding, harvesting aligned to moon phases and zodiac cycles (root days, flower days, fruit days, leaf days)
• Certification: Demeter (gold standard biodynamic certification; worldwide)
• Strong in Europe; growing in India (bio-dynamic wine, vegetables)

Permaculture (Bill Mollison and David Holmgren)

• Permanent Agriculture + Culture; Australia; 1970s
• Design science mimicking natural ecosystem structure and function
• Zones (1–5) from intense management to wilderness; guilds (mutually beneficial plant combinations)
• Food forests: multilayer productive systems (canopy → sub-canopy → shrub → herb → ground cover → vine → root)
• Global movement; strongly aligned with organic and natural farming

Syntropic Farming (Ernst Gotsch, Brazil)

• Succession-based farming on degraded land
• Chop-and-mulch: regular pruning of fast-growing pioneer species; biomass used as mulch
• Mimics ecological succession; soil builds rapidly
• Extremely effective for land restoration
