This study investigated the changes in physicochemical properties and bacterial community during swine manure composting using a new compost tray. The results showed a decrease in organic matter and moisture content, while total nitrogen, P2O5, K2O, and humic acids increased. Firmicutes, Actinobacteria, Proteobacteria, and Bacteroidetes were the dominant phyla during composting.
The objective of this study was to explore the changes in physicochemical properties and bacterial community during swine manure composting with a new compost tray (CT). The results showed that the organic matter (OM), moisture content (MC), and C/N decreased. The total Kjeldahl nitrogen (TKN), P2O5, K2O and humic acids (HAs) contents of the compost increased. The properties of the final compost product comply with the requirements of regulation except for the moisture according to NY/T 525-2012. Firmicutes, Actinobacteria, Proteobacteria and Bacteroidetes were the major phyla during the composting. Genus Terrisporobacter played a key role in degrading organic (OM). The content of K2O was main factors driving the succession of bacterial communities. These findings shed some novel lights into the dynamic changes of physicochemical propertied and their impact on bacterial community in a composting process.
