Chicken manure is a high-quality organic fertilizer, which contains about 1.63%, 1.54% and 0.85% of pure nitrogen, phosphorus (P2O5) and potassium (K2O). Chicken manure must be thoroughly decomposed before application. Parasites and their eggs in chicken manure, as well as some infectious bacteria, will be decomposed (fermented) and inactivated.

Because chicken manure produces high temperature during decomposition, it is easy to cause nitrogen loss. Therefore, adding proper amount of water and 5% calcium superphosphate before decomposition will have better fertilizer efficiency. For the decomposition method, chicken manure can be soaked in septic tanks or covered with soil for composting. After chicken manure is fully decomposed, it becomes a high-quality base fertilizer for planting crops, or it is used as a base fertilizer for planting fruit trees in winter all the year round.

Extended information:

Into the modern chicken farm in Shi Ming, more than 200,000 laying hens drank water, pecked and laid eggs leisurely in the three-story fence. 100 meter long conveyor belt keeps running, and eggs and chicken manure are sent to the packaging room and fertilizer plant respectively. When I met President Ming, he was busy with 12 employees in the packaging room of his "laying hen factory".
