How are microbial innoculants used to increase the soil fertility?

Explanation

Biofertilizers or microbial innoculants are defined perparations containing living cells or latent cells of efficients strains of microorganisms that help crop plants uptake of nutrients by their interactions in the rhizosphere when applied through seed and soil. They are efficient in fixing nitrogen, solubilising phosphate and decomposing cellulose. They are designed to improve the soil fertility, plant growth, and also the number and biological activity of beneficent microorganisms inthe soil. They are ecofriendly organic agro inputs and are more efficients and cost effective then chemical fertilizers.
