Biofertilizers contain living microorganisms which, when applied to seed, plant surfaces, or soil, colonizes the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. They serve as a suitable alternative to chemical fertilizers by adding nutrients through the natural processes of solubilizing phosphorus, nitrogen fixation, and stimulating plant growth through the synthesis of growth-promoters. Biofertilizers are cost effective, and serve as renewable sources of plant nutrients which supplement chemical fertilizers. Different types of biofertilizers are present such as nitrogen fixing biofertilizers, phosphate solubilizing biofertilizers, potash mobilizing biofertilizers and others.
