Bio-fertilizers are being essential component oforganic farming are the preparations containing live or latent cells ofefficient strains of nitrogen fixing, phosphate solubilizing or cellulolyticmicro-organisms used for application to seed, soil or composting areas with theobjective of increasing number of such micro-organisms and accelerate thosemicrobial processes which augment the availability of nutrients that can beeasily assimilated by plants. Biofertilizers play a very significant role inimproving soil fertility by fixing atmospheric nitrogen, both, in associationwith plant roots and without it, solubilise insoluble soil phosphates andproduces plant growth substances in the soil.
The increasing demand for the biofertilizers and theawareness among farmers and planters in the use of biofertilizers have pavedway for the fertilizer manufactures and new entrepreneurs to get intobiofertilizer production. Bio-fertilizers Demand is much higher than theavailability. It is estimated that by 2020, to achieve the targeted productionof 321 million tonnes of food grain.
