According to different production methods of organic manure, organic manure can be divided into compost, compost, manure, biogas, green manure, straw manure and other organic manure according to different raw materials and processes. Compost refers to a kind of organic fertilizer that is made of crop straw, breeding manure, animal carcass and other breeding wastes, rice husks, grass and other raw materials and mixed with a small amount of soil. The difference between compost and compost is that the organic manure produced by fermentation under submerged conditions uses the same raw materials as compost. The raw materials used for the manure are the manure of pigs, cattle, horses, sheep, chickens, ducks and other livestock and poultry, as well as the bedding materials in the pens, and the composted fertilizer. The raw material source of biogas fertilizer is the same as that of compost. The process is that after biogas is produced by anaerobic fermentation, the remaining biogas liquid and residue are the by-products after biogas production. Green manure is the use of green plants as fertilizer. The raw materials of straw fertilizer include corn, rice and other crop stalks. Under appropriate conditions, the elements in the straw will be mineralized and returned to the soil through the action of soil microorganisms, and then be absorbed and utilized by crops. There are other organic fertilizers such as rapeseed cake, cottonseed cake, bean cake, sesame cake, castor bean cake, tea seed cake and unpolluted river mud, pond mud, ditch mud, port mud and lake mud.

General organic fertilizer production line process of commercial organic fertilizer: the general production process of commercial organic fertilizer includes: inoculation fermentation (pre fermentation), main fermentation, crushing, compounding and mixing, drying, granulation, cooling, screening, metering and packaging of organic materials. The main equipment of the organic fertilizer equipment processing process includes fermentation tank, mixer, overturning equipment, belt conveyor equipment, cylinder screen, pulverizer, granulator, etc.
