Organic fertilizers are fertilizers derived from plant extract, animal matter, animal extract(manure), human excreta, and vegetable matter(e.g. compost and crop residues). Naturally occurring organic fertilizers include animal wastes from meat processing, peat, manure, slurry, and guano.
Corn steep liquor is an efficient raw material for organic fertilizer.
As for its many organic supplements, it can active the soil biologically by stimulating nitrogen fixation and symbiotic plant-microorganism interaction, restoring natural soil fertility through the production of organic material, so as to improve soil structure, texture, and aeration and increasing the soil’s water-holding capacity.
