Composting is an environmentally friendly method for disposing of solid waste. To enhance the fermentation rate and quality deer manure composting, we investigated effects various conditioners (biochar, zeolite, biochar + zeolite) on aerobic composting process manure. The results indicated that combination zeolite significantly promoted degradation organic matter, resulting in a 34.83% decrease total carbon (TOC) content. addition was particularly beneficial nitrogen retention compost, with content reaching its highest level at 39.55 g/kg. Furthermore, inclusion altered phosphorus demonstrating more favorable effect. conditioner increased relative abundance Ascomycota Proteobacteria decreased Firmicutes; changes Corynebacterium, Acinetobacter, Glutamicibacter were positively correlated carbon-to-nitrogen ratio (C/N ratio) negatively (TN) (TP) levels. mixed used exhibited low toxicity degree decomposition. In summary, as optimal choice reducing compost promoting maturation. Further research will be conducted future to promote resource utilization agricultural wastes such

With economic development and improvements in living standards, the demand for livestock products has steadily increased, resulting generation of large amounts manure, which seriously pollutes ecological environment poses a threat to human health. High-temperature aerobic composting is an effective method treating manure; however, traditional processes often lead considerable nitrogen loss, reduced efficiency soil conditioners, increased emissions harmful gases. The incorporation physical, chemical, biological additives can effectively retain within compost. Among these, microbial agents are particularly noteworthy as they precisely regulate community structure associated with transformation during composting, altering abundance functional genes enzyme activities involved transformation. This approach significantly reduces loss gas emissions. paper reviews application effects on retention explores underlying regulatory mechanisms, aiming provide theoretical guidance new research directions enhancing composting.
