Abstract: At present, livestock manure is an important cause of agricultural non-point source pollution. The nitrogen, phosphorus and potassium resources in livestock manure account for a higher proportion of fertilizer consumption in the same period, and have better potential to replace fertilizer. Combining the current situation with planting and breeding is an ideal solution to solve the problem of livestock manure pollution. Through the combination of full-scale returning and composting, it can accelerate the treatment and recycling of livestock and poultry farming waste, and effectively control agricultural non-point source pollution. Improve the living environment.
