  • Subhash Palekar, the man behind the idea of ZBNF came in the Union Budget speech of FM where she talked of the need to “go back to basics” and replicate this innovative model that can help in doubling our farmers.

What is Zero Budget Natural Farming (ZBNF)?

  • ZBNF is a set of farming methods, and also a grassroots peasant movement, which has spread to various states in India.
  • According to the “zero budget” concept, farmers won’t have to spend any money on fertilisers and other agricultural inputs.
  • Over 98% of the nutrients that crops require — carbon dioxide, nitrogen, water, solar energy — are already present in nature.
  • The remaining 1.5-2% are taken from the soil, after microorganisms convert them from “non-available” to “available” forms, for intake by the roots.
  • This is where the special package of practices which, Palekar says he perfected during the 1990s at his 36-acre farm in Belura village of Amravati district in Maharashtra’s drought-prone Vidarbha region, comes in.

Four Wheels of ZBNF

  • The “four wheels” of ZBNF are ‘Jiwamrita’, ‘Bijamrita’, ‘Mulching’ and ‘Waaphasa’.
  • Jiwamrita is a fermented mixture of cow dung and urine (of desi breeds), jaggery, pulses flour, water and soil from the farm bund.
  • This isn’t a fertiliser, but just a source of some 500 crore micro-organisms that can convert all the necessary “non-available” nutrients into “available” form.
  • Bijamrita is a mix of desi cow dung and urine, water, bund soil and lime that is used as a seed treatment solution prior to sowing.
  • Mulching, or covering the plants with a layer of dried straw or fallen leaves, is meant to conserve soil moisture and keep the temperature around the roots at 25-32 degrees Celsius, which allows the microorganisms to do their job.
  • Waaphasa, or providing water to maintain the required moisture-air balance, also achieves the same objective.

Astra’s of ZBNF against pest attacks

  • Palekar also advocates the use of special ‘Agniastra’, ‘Bramhastra’ and ‘Neemastra’ concoctions — again based on desi cow urine and dung, plus pulp from leaves of neem, white datura, papaya, guava and pomegranates — for controlling pest and disease attacks.

Is it organic farming?

  • ZBNF uses farmyard manure or vermicompost mostly produced from Eisenia fedita, a species imported from Europe and Canada.
  • These foreign earthworms accumulate heavy metals like lead, arsenic and cadmium, which get transferred into their castings that, far from being manure, are actually toxic to the soil.
  • So, the soil fertility, instead of improving, only reduces”.
  • He says that in ZBNF, the work of making nutrients available to plants is done exclusively by microorganisms from Jiwamrita and “local earthworms”.

However, not all farmers are convinced about ZBNF. Why?

  • The cost of labour for collection of dung and urine, apart from the other inputs used in preparation of Jiwamrita, Neemastra or Bramhastra is quit higher.
  • Keeping cows is also a cost that has to be accounted for. Farmers cannot afford to keep desi cows that yield very little milk.
  • If ZBNF is practiced in isolation, the crop grown would be vulnerable to attacks by insects and pests which may move there from fields where chemical pesticides are being sprayed.
  • Many state governments, including Kerala, Karnataka, Andhra Pradesh, Himachal Pradesh, Chhattisgarh and Karnataka have openly supported ZBNF after studying its efficacy.
