NOVELTY - Production process of organic bio-fertilizer, by adding crushed cow dung and straw, and humic acid, amino acids and chelating agent to fermentation tank, adding inoculum, subjecting mixture to fermentation, reducing water content of the mixture, inoculating microbial inoculum on fermented material, deodorizing material, composting fermented product, dehydrating compost, adding chelating agent, amino acids, binders and urea to obtained active organic fertilizer, drying and sieving mixture, spray-granulating mixture and packaging granulated product.    USE - Production process of organic bio-fertilizer (claimed).    ADVANTAGE - The method enables preparation of high efficient and multifunctional organic bio-fertilizer that effectively regulates or adjusts ecological balance of microorganisms in soil, eliminates use of chemical fertilizer that often results in soil hardening/compaction, salinization, and desertification, improves quality of crops, controls diseases in plants, and serves as ideal fertilizer for production of green food.    DETAILED DESCRIPTION - Production process of organic bio-fertilizer, involves (a) crushing cow dung and straw, adding obtained crushed cow dung and straw, humic acid, amino acids and chelating agent in predetermined weight proportions to fermentation tank, adding inoculum to the tank and subjecting mixture in the tank to continuous aerobic fermentation process under heating and good aeration conditions, and (b) allowing fermentation to occur for 5-7 days until water content of materials in the tank reduces to 40% or less, inoculating microbial inoculum directly on surface of obtained fermented product, allowing deodorization to occur for 5-7 days, composting the fermented product, dehydrating obtained compost to obtain active organic fertilizer, adding chelating agent, amino acids, binders and urea to the active organic fertilizer, drying obtained mixture, sieving the mixture, subjecting the mixture to spray-granulation machine and packaging obtained granulated product by automatic packaging machine to obtain final product.
