Advanced fermentation process. The combination of membrane mulching technology can maximize nutrients and reduce nitrogen loss, with small infrastructure and less labor and energy consumption. Shorten the fermentation cycle and maximize the retention of organic matter and nutrients in the manure. It is more suitable for the mechanism and process requirements of microbial fermentation of livestock and poultry manure into fertilizer. It can effectively mix viscous livestock and poultry manure with microbial preparations, straws and other auxiliary materials to create a better aerobic environment for material fermentation.
