Why we need to use of biofertilzer.....Due to high in price of fertilizers, especially those of phosphatic and potassic fertilizers, and also the shortage of fertilizers, searching of alternate option hold promise for reducing cost of cultivation. Further, efficiency of phosphatic and potassic fertilizers is low due to fixation in calcareous soil. Organic manures can replace fertilizers up to 50%, but the availability and cost of organic manures are further become constraints. It thus becomes urgent to investigate the bio-solubilisation of soil P and K reserves so as to alleviate the phosphatic and potassic fertilizer shortage. Several strains of bacteria and fungi have been identified for P and K solubilization.
