The researchers studied how compost made from swine manure and rice hulls matures in a large-scale composting facility. They found that the temperature of the compost pile reached 76°C at day 15 and stayed above 62°C for 25 days. Water content decreased by about 20% over 25 days. The presence of specific microbes indicated the compost's stability. Ammonium-N to Nitrate-N ratio and seed germination were key indicators of compost quality. The ratio of Humic acid changed during composting, and soluble carbon and nitrogen levels fluctuated throughout the process.
