Bio-organic fertilizer refers to a type of environmentally friendly fertilizer compounded by combining specific functional microorganisms with organic materials derived primarily from animal and plant residues (such as livestock manure, crop straw, etc.). These organic materials must undergo harmless treatment and complete decomposition processes.

This fertilizer integrates the dual effects of microbial fertilizer and organic fertilizer:

l The decomposed organic components can supplement soil organic matter, improve soil structure, and provide basic nutrients for crop growth.

l The added functional microorganisms (e.g., nitrogen-fixing bacteria, phosphorus-solubilizing bacteria, potassium-solubilizing bacteria) can activate fixed nutrients in the soil, inhibit the reproduction of soil-borne pathogenic microorganisms, and promote the absorption and utilization of nutrients by crops.
