Bio fertilizers contain living microorganisms, which when made in contact with the seeds, plants or soil, rejuvenates the interior system of the plants and promotes the growth by providing invariant nutrients essentially needed by the plants. Prolonged use of chemical fertilizers degrades the soil and affects the crop yield. Bio fertilizers, on the other hand, enhance the water holding capacity of the soil and add essential nutrients such as nitrogen, vitamins and proteins to the soil.
