How to properly use a biofertilizer ?

Biofertilizer packets need to be stored in cool and dry place away from direct sunlight and heat. Right combinations of biofertilizers have to be used. As Rhizobium is crop specific, one should use for the specified crop only. Other chemicals should not be mixed with the biofertilizers. Biofertilizers are live product and require care in the storage. Both nitrogenous and phosphatic biofertilizers are to be used to get the best results.
