Abstract
The aim of this study is to reduce nitrogen (N) loss and investigate the role of ammonia (NH3) recycling on N fractions, environmental factors and bacterial communities. In this study, collected NH3 from composting and recycled in it. The results showed that NH3 recycling affected N-cycling processes such as nitrification. Redundancy Analyses (RDA) showed that NH4+-N had significantly negative correlation with denitrifying bacteria in treatment group (p < 0.05), demonstrating that NH3 recycling have influenced on the bacterial community structure. Furthermore, Structural Equation Model (SEM) revealed causal relationships between visual variables. Based on these results, we concluded that NH3 recycling is a novel method to reduce N loss.Entities:
