Organic manure is a well decomposed material used in organic agriculture it is free from chemicals,harmful organisms and weed seeds either it is from a animal or plant origin.Organic manures increase the organic matter in the soil. Organic matter in turn releases the plant food in available from for the use of crops.
A biofertilizer is a substance which contains living micro-organisms which, when applied to seeds, plant surfaces, or soil, colonize 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 add nutrients through the natural processes of nitrogen fixation, solubilizing phosphorus, and stimulating plant growth through the synthesis of growth-promoting substances. The microorganisms in biofertilizers restore the soil's natural nutrient cycle and build soil organic matter.
