Context: Biochar can affect the storage and forms of nitrogen; thus, it may also play a role in altering nitrogen cycle during fermentation process cow dung into organic fertilizer. Objective: To elucidate mechanism transformation composting manure with biochar, comparative experiment was conducted. Method: This study investigates use biochar as medium to enhance aerobic manure. The effectiveness verified through rapid experiment. Result Conclusions: results demonstrated that adding 5% compost pile increased total content by 12%. Specifically, pyrrolic composted from 38% 44%, carbon-nitrogen ratio improved 35% 37%. Analysis surface functional groups indicated C=O C=C bonds played key modifying storage. Microbial analysis showed could significantly regional competitiveness microorganisms, such Cellvibrio, thereby boosting expression genes involved nitrification process, including amoABC, hao, nxrAB. Therefore, not only enhances fertilizer but changes microbial population structure. Significance: carries substantial implications for application field, well development fertilizers based on
