Abstract: With the rapid development of the global livestock industry,the amount of livestock and poultry manure generated has increased annually,making the efficient utilization of this manure particularly important.Among the various manure treatment methods,such as feed conversion,energy production,and biogas fermentation,the composting process is considered the most effective method for decomposing organic matter in livestock and poultry manure into high-quality,harmless organic fertilizer,which is essential in promoting sustainable agricultural development and environmental protection.However,traditional composting methods often encounter issues such as prolonged fermentation cycles and incomplete decomposition,which limit both fermentation efficiency and effectiveness.Therefore,this paper analyzes the innovative approach of modern composting technology that employs exogenous microorganisms as an auxiliary method.This approach not only significantly enhances the fermentation efficiency of livestock and poultry manure but also improves the quality of the final product,thus opening new pathways for the resourceful utilization of this manure.The article reviews the impact of microbial agents in sheep manure composting,specifically examining the effects of exogenous microbial agents on the abundance and diversity of compost flora,as well as their influence on the enhancement of compost’s physicochemical properties,drawing on studies conducted by scholars both domestically and internationally.The effects of applying microbially fermented sheep manure on soil physicochemical properties and crop quality are further examined,highlighting the significant role of microbial agents in sustainable agricultural development.Additionally,this paper foresees the future development of microbial agents in the resourceful utilization of manure,aiming to provide a scientific basis for the sustainable development of agriculture.
