Humic substances affect compost stability and maturation. However, the intricate structure of lignocellulosic materials hinders biodegradation cellulose, hemicellulose, lignin, often promoting use synthetic additives which results in microbial inactivation death. Therefore, this study examined effects optimal moisture levels (MC1 = 45%, MC2 55%, MC3 65%) on humification fractions aerobically co...
