At present, there are three types of microbial fertilizers registered in China, namely, bio-organic fertilizers, agricultural microbial agents and compound microbial fertilizers.

Bioorganic manure is a combination of specific functional microorganisms and organic materials mainly composed of animal and plant residues (such as livestock manure, crop stalks, etc.) and harmlessly processed and decomposed organic materials. Fertilizer effect fertilizer. It is characterized by the addition of functional microbes, powders and granules, in high quality organic fertilizers (after rotting).

The agricultural microbial agent is a viable product that is produced by the direct use of one or more functional microorganisms (effective viable bacteria) after industrial production, proliferation, or concentration or carrier adsorption. It is characterized by a high number of bacteria and a small amount of liquids, powders and granules.

Compound microorganisms refer to viable bacteria products that are produced by compounding nutrient substances (nitrogen, phosphorus, potassium, etc.) after the industrialized production of the target microorganisms. Features include functional bacteria, NPK nutrient and organic carrier composition, balanced fertilizers for quick and long-term supply needs, there are three formulations of liquids, powders and granules.
