A Review of Studies on Nitrogen Loss During the Composting of Chicken Manure
Aerobic composting is one of the main technical methods to achieve the resource utilization of chicken manure.However,nitrogen loss is serious during chicken manure composting,which not only reduces the fertilizer efficiency,but also causes severe non-point source pollution.This paper summarizes the main causes of nitrogen loss during chicken manure composting,and reviews the effects of initial C/N,initial moisture content,turning frequency,and additive types on nitrogen loss during chicken manure composting.It is concluded that the optimal initial C/N,initial moisture content,and turning frequency for reducing nitrogen loss during chicken manure composting are 20-25,60％-65％,and once/7d,respectively.Compound additives can reduce nitrogen loss during composting more than single additives.Finally,the future research prospects of chicken manure composting are proposed.This paper provides a theoretical basis for the study of nitrogen loss during chicken manure composting.
