Bio-FertilizerNFL manufactures and markets four types of Bio-Fertilizers, Rhizobium, Phosphate Solubilising Bacteria (PSB) and Azotobacter and Zinc Solubilising Bacteria (ZsB). Starting with a mere 23 MT production in 1995-96, the production has risen to 630 MT (Approx) in 2019-20. The Company presently markets its bio-fertilizers in Madhya Pradesh, Maharashtra, Uttar Pradesh, Uttrakhand, Chattisgarh, Bihar, Jharkhand, Punjab, Haryana, Rajasthan, Andhra Pradesh, Telangana.

Bio-fertilizers are used to supplement chemical fertilizers as also to maintain soil fertility; besides the following:-

  1. Bio-Fertilizers are supplement to Chemical Fertilizers.
  2. Bio-Fertilizers are cheap and can reduce the cost of cultivation.
  3. Fix Biological Nitrogen in the soil, which is readily available to the plant.
  4. Increase crop yield by 4-5% on an average.
  5. Improve soil properties and sustain soil fertility.
  6. Provides plant nutrient at low cost and useful for the consecutive crops.

The applicability of Bio-Fertilizers marketed by NFL of different crops is as under:

4. Zinc Solublising Bacteria (ZSB)

a) Suitable for different type of soils with pH in the range of 6.5 to 8.5.

b) Solubilizes Zinc for various sources like Zinc oxide, Zinc Phosphate and Zinc Carbonate.

c) Increases uptake of Zn leading to fortification of grains with Zinc.

d) helps to solubilize the fixed form of Zn in the soils

Cereals, millets, pulses, vegetables, fiber and oil seed crops
