摘要： The significant volatilization of NH3 during aerobic composting causes nitrogen (N) losses and environmental risks. Both iron (Fe) and biochar (BC) can influence the N conversion process in composting. Fe application can delay the maturation of materials, while biochar can enhance the quality of organic fertilizer. The combination of these two conditioners may help decrease NH3 emissions and improve organic fertilizer quality. Therefore, this study investigates the effects of different doses of FeCl3 and BC on NH3 emissions and organic fertilizer quality during composting. The results demonstrated that Fe/BC co-conditioners reduced the accumulation of NH3 emissions during composting by 11.1-48.2%, increased the total nutrient content by 0.6-15.3%, and enhanced economic and environmental benefits by 0.1-23.6 $ t(-1). At the high-temperature stage of composting, Fe/BC co-conditioners decreased the pH by 0.3-1.2, but there was no significant difference compared to the control at the end of composting, and they did not affect compost maturation. The structural equation model analysis suggested that the reduction in NH3 emissions was related to ammonia-oxidizing bacteria (AOB), NH4+-N, and total nitrogen (TN). As a result, the Fe/BC co-conditioners reduced NH3 emissions by lowering the pH at the beginning of composting and increasing the content of NH4+-N. This study concludes that Fe/BC co-conditioners could complement each other to significantly reduce NH3 emissions and improve the quality of organic fertilizers.
