The decrease in organic matter content reveals that the degradation rate is active. Many microbes utilize this organic matter by mineralization. The study was designed to check the effect of different organic wastes used as a substrate on organic matter. It was concluded from this study that different organic waste substrate show variation in organic matter during the process of composting. The highest value of organic matter was observed in experimental heap with humic acid addition and the lowest was observed in control heap. Copyright@ International Science Community Association
