Biofertilizer-Beneficial for sustainable Agriculture and improving soil fertility

A. J. Patangray

Abstract


‘Biofertilizer’ is a substance which contains living microorganism which, when applied to seed, plant surfaces, or soil, colonizes the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. Biofertilizers are not fertilizers. Fertilizers directly increase soil fertility by adding nutrients. Biofertilizers add nutrients through the natural processes of fixing atmospheric nitrogen, solubilizing Phosphorus, and stimulating plant growth through the synthesis of growth promoting substances. Biofertilizers contained 3.5% - 4% nitrogen, 2% - 2.5% phosphorus and 1.5% potassium. They can be grouped in different ways based on their nature and function. This enriches soil quality by improving its physicochemical and biological properties. It is eco-friendly, non-toxic, consumes low energy input for composting and is a recycled biological product.
