Abstract：The aim of this study was to review the mechanism of humic acid formation and the regulation method for improving the humification degree by process parameter optimization, the exogenous additives, and so on, in composting. The mechanisms of various regulation methods for accelerating humic acid formation process were also discussed, which provided theoretical basis for the development of fast composting technologies. Various regulatory methods may be interacted in applications due to the complex dynamic physiochemical environment factors in composting. Therefore, it is necessary to establish an integrated relationship among more factors related to humic acid formation based on practical compost production process. The future regulating methods will help to improve the quality of composting products.
