Livestock and poultry manure has the property of resource, which can be returned to the field for utilization and production of organic fertilizer. The fertilizer utilization of livestock manure organic fertilizer equipment can further improve the content of soil organic matter, improve the quality of agricultural products and ensure the sustainable production capacity of farmland. In traditional agriculture, livestock and poultry feces are generally simply piled up and fermented, and then applied to farmland after fermentation. This method reduces the planting cost and also makes livestock and poultry feces treated. However, this treatment method has insufficient fecal fermentation, affects crop growth, and is easy to cause secondary environmental pollution

In terms of output scale, the small-scale organic fertilizer equipment processing plant takes the annual output of 10000-30000 tons as the standard, which is also the production line scale most selected by new investors. Since it is a production line, it is not composed of single equipment or 2-3 equipment. The complete set of equipment consists of a variety of equipment. Their type selection, specification and quantity directly affect the final price of the production line, that is, the price of the production line with the same output is not the same, or even very different. Under the same output, the powdered production line is much cheaper than the granular production line, but the corresponding powdered finished organic fertilizer has no higher price and profit than the granular organic fertilizer.
