A PILOT SCALE PROCESS FOR THE PRODUCTION OF HIGH SHELF LIFE MULTI-FUNCTIONAL LIQUID BIOFERTILIZERS

The mass production of liquid biofertilizers on the industrial scale with high cell viability and shelf life is still in infancy. Cost effective pilot scale (50l) process developed at purti enterprises, nagpur exhibits a high viability for azotobactor (1 x 1015), acetobactor (1 x 1015), psudeomonas (1 x 1018), frateuria (1 x 1017), bacillus (1 x 1017), trichoderma (2 x 109). The liquid biofertilizers were kept at room (28 ± 2°c) for shelf-life study. Liquid biofertilizers showed a significantly high viable count after storage of one to one and half year.
