Abstract:

In China, the amount of livestock and poultry manure produced every year is huge and can cause pollution to soil, waterbody and air through long-term accumulation. The major way to treat livestock and poultry manure is aerobic composting. Since there are problems such as ammonia loss in the composting process, amendments can be added to reduce ammonia gas volatilization and pH, and improve the microbial community structure of the compost pile, thus decreasing nitrogen loss. The application features of several amendments and their regulating role in nitrogen transformation in the composting process of livestock and poultry manure are summarized in this study, and the primary issues in the composting process are listed. Additionally, the study discusses the development trend of livestock and poultry manure treatment and the resource utilization, hoping to provide reference for future research.

Key words: livestock and poultry manure, compost transformation, amendments, functional characteristics, nitrogen transformation
