An organic fertilizer fermentation tank is a device that converts organic solid waste into organic fertilizer through aerobic fermentation of microorganisms in a closed container. It utilizes the decomposition of microorganisms in nature, matures the materials through high temperature and microbial activity, kills harmful substances and reduces the moisture content and volume of the materials.

In livestock farming, incorporation of fermentation technology can highly enhance feed nutritional value. Processed via microbial action, fermented livestock and poultry excreta becomes biofertilizer rich in nitrogenous compounds like ammonia, urea, nitrates or nitrites; phosphorous as phosphate salts; potassium ions; and organic matter. It enhances waste utilization. Organic fertilizers not only enhance soil fertility but also promote improved plant growth leading to high yields.

In general, as an important environmental protection equipment, organic fertilizer fermentation tank is beneficial to the development of agriculture and animal husbandry. In the pursuit of sustainable development today, organic fertilizer fermentation tank will play its advantages in more fields.
