How to determine if fermentation is complete? Criteria for judging the maturity of organic fertilizer
The pile temperature drops to the same level as the outdoor temperature, and the moisture content is below 30%. How to determine if fermentation is complete? The two most direct and definitive indicators of the completion of aerobic fermentation and maturity of organic fertilizer are: the pile temperature dropping to the same level as the outdoor temperature and the moisture content dropping below 30%. When the pile temperature no longer rises and stabilizes at the same level as the ambient temperature, and the material moisture content drops below 30%, fermentation can basically be considered complete. However, to ensure thorough maturity and fertilizer safety, it is necessary to combine indicators such as color, odor, structure, and germination rate for a comprehensive judgment.
