Biofertilizer is a substance which contains living microorganism which, when applied to seed, plant surfaces, or soil, colonizes the rhizophore or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. Biofertilizers add nutrients through the natural processes of fixing atmospheric nitrogen, solubilizing Phosphorus, and stimulating plant growth through the synthesis of growth promoting substances. They can be grouped in different ways based on their nature and function. There are various kinds of biofertilizers like Rhizobium, Azotobacter, Azospirillum, Cyanobacteria, Azolla, Silicate Solubilizing Bacteria (SSB) etc. Applications Biofertilizers are microorganisms that help plants to grow by increasing the quantity of nutrients. Since these fertilizers contain living microorganisms, it increases or promotes the supply of important nutrients crucial for the overall productivity of the soil. An increasing number of farmers and agriculturists are turning to the use of biofertilizers as these are gentler on the soil as against chemical fertilizers. ?
