Bio fertiliser

Low cost, environment-friendly, Biofertilisers are an essential source of plant nutrient

Biofertilisers are capable of fixing atmospheric nitrogen when suitable crops are inoculated with them. Biofertilisers are low cost, effective, environmental friendly and renewable source of plant nutrients to supplement fertilisers. Integration of chemical, organic and biological sources of plant nutrients and their management is necessary for maintaining soil health for sustainable agriculture. The bacterial organisms present in the biofertiliser either fix atmospheric nitrogen or solubilise insoluble forms of soil phosphate. The range of nitrogen fixed per ha/year varies from crop to crop; it is 80 - 85 kg for cow pea, 50 - 60 kg for groundnut, 60 - 80 kg for soybean and 50 - 55 kg for moongbean.

Phosphate Solubilising Micro Organism

Several soil bacteria and fungi possess the ability to bring insoluble phosphates into soluble forms by secreting organic acids. They can be applied to and recommended for all crops


It is the most important nitrogen fixing organism. It live symbiotically in the root nodules of leguminous plants and supply nitrogen to the plant through nitrogen fixation. Besides, supplying nitrogen to the crop, nitrogen fixed by legume - Rhizobia association would also leave residual nitrogen for the succeeding crops. The beneficiary crops are Groundnut, Soybean, Red-gram, Green-gram, Black-gram, Lentil, Cow pea, Bengal-gram and Fodder legumes.


It is non symbiotic nitrogen fixing bacteria recommended for non leguminous crops like Paddy, Wheat, Millets, Cotton, Tomato, Cabbage, Mustard, Safflower and Sunflower. The Azotobacter performs well if the soil organic matter content is high.


It is a symbiotic bacteria capable of fixing atmospheric nitrogen by living within the sugar plant. They are found in all parts of plant body. It is suitable for sugarcane cultivation.


It is an associative microaerophilic nitrogen fixer is commonly found in association with the roots of cereals and forage grasses. The beneficiary crop include Sugarcane, Vegetables, Maize, Pearl millet, Rice, Wheat, Fodders and Oil seeds.
