2. The main substance in chicken manure is organic matter, which increases the content of organic matter in the soil. Organic matter can improve the physical, chemical and biological properties of soil, mature the soil and fertilize the soil. In the countryside of our country, "the ground is manure raised, Miao is manure long" proverb, which reflected in large extent the function of chicken manure for improving the soil.

3, chicken manure not only increased a lot of organic colloid, at the same time with the role of microorganisms to decompose many organic matter into organic colloid, which greatly increased the soil adsorption surface, and produce a lot of adhesive material, the soil particles cemented up into a stable aggregate structure, improve the soil water retention, fertilizer protection and breathable performance, as well as the ability to adjust the soil temperature.

4, chicken manure can also make soil microorganism mass reproduction, especially many beneficial microorganisms, such as azotobacter, ammoniating bacteria, cellulose decomposition bacteria, nitrification bacteria, etc. Chicken manure contains various active enzymes secreted by animal digestive tract, as well as various enzymes produced by microorganisms. After applying these substances to soil, soil enzyme activity can be greatly improved.

Chicken manure as organic fertilizer can be used in three ways: directly as organic fertilizer after drying, or as raw material for organic and inorganic compound fertilizer production. Organic fertilizer equipment after fermentation directly used as organic fertilizer, or used as raw materials for organic fertilizer production. Fermentation, can be mixed with straw, lees and other organic materials after fermentation. It can be used for compost fermentation, or biogas fermentation and then mixed with other organic materials after biogas residue for compost fermentation, and then directly applied as organic fertilizer or used as raw materials for other organic fertilizer. After fermentation and drying, it is directly used as organic fertilizer, or used as raw material for other organic fertilizer production.
