The “microbial inoculum+molecular membrane” fermentation process to improve the co-composting efficiency of straw and animal manure
To make better use of agricultural waste and improve the nutritional efficiency of compost products, a novel “microbial inoculum+molecular membrane” fermentation process was used to investigate the physicochemical properties, maturity, humification, and dynamics of phosphorus components in the co-co...

| description | To make better use of agricultural waste and improve the nutritional efficiency of compost products, a novel “microbial inoculum+molecular membrane” fermentation process was used to investigate the physicochemical properties, maturity, humification, and dynamics of phosphorus components in the co-composting process of straw and animal manure. The results demonstrated that the variations in total organic carbon (TOC), moisture content (MC), C/N ratio, and fulvic acid (FA) decreased significantly while the contents of total nitrogen (TN), humic acid (HA), total phosphorus (TP), and available phosphorus (AP) increased significantly (p<0.05), which indicated that the maturity and nutritional level of co-composted products had been improved. In addition, the humification index and 31P nuclear magnetic resonance (31P-NMR) spectrum analysis revealed an increase in the degree of humification and a change in phosphorus composition within the compost. In accordance with NY/T 525—2021 regulations, all aspects of the final compost product meet the required standards except for moisture content. The findings of this study can offer a comprehensive comprehension of the enhancement in composting efficiency through the “microbial inoculum+molecular membrane” fermentation process, and provide a scientific and practical approach for achieving agricultural waste recycling. |
