Definition of Bio-organic Fertilizer and Core Control of Live Bacteria Survival
According to the agricultural industry definition, bio-organic fertilizer refers to a type of fertilizer that combines the effects of microbial fertilizer and organic fertilizer, composed of specific functional microorganisms and organic materials mainly derived from animal and plant residues (such as livestock and poultry manure, crop straw, etc.) that have undergone harmless treatment and composting. Its core technical indicators require an effective live bacteria count (CFU) of not less than 0.2 billion/gram, organic matter (on a dry basis) of not less than 40%, and moisture content not exceeding 30%. Unlike ordinary organic fertilizer, which only pursues harmlessness and composting degree, the core value of bio-organic fertilizer lies in the activity of “functional bacteria”—these beneficial microorganisms (such as Bacillus subtilis, Bacillus licheniformis, etc.) can colonize and reproduce after being applied to the soil, playing multiple functions such as improving soil, inhibiting diseases, and promoting crop absorption.
