Abstract:

Adding BioAg biological agent during composting is beneficial for compost maturity and organic matter decomposition. It can effectively eliminate pathogenic bacteria, insect eggs, and weed seeds, thereby improving composting efficiency. In this experiment BioAg biological agent was added at different application doses to organic compost. Comparisons of composting efficiency showed that adding the BioAg biological agent promoted a rapid rise in compost temperature and accelerated the maturation process. Under the addition dose of 1 L·t^-1, the nutrient content was higher compared with the control. The addition of the BioAg biological agent also promoted an increase in available nitrogen content. However, excessive addition of the BioAg inoculant may decrease the phosphate and potassium.

Key words: biological agent, formula, composting, maturity
