The maintenance of moisture is very important in composting process. Moisture content is a dominant parameter in composting as it is necessary for the activity of microbes. It enhances the metabolic rate of microbes and hence increases the rate of degradation. This study was designed to observe the effect of substrate on moisture percentage. The 50% moisture was optimized in all windrows containing different substrate. It was concluded from this research that the greater moisture showed by substrate composed of cow dung+ screening matter + green waste + paper and lowest was shown by waste composed of cow dung+ screening matter + green waste + saw dust. The decrease in moisture % in all treatments was observed. The decrease in moisture from 50% is a sign of compost maturity and high activity of microorganisms and better degradation.
