This study was carried out to examine the nutrient composition of biodegradable waste composts and sawdust. Three types of compost were produced from sawdust only, sawdust mixed with poultry litter and sawdust mixed with domestic and market wastes. The physical, chemical and nutrients properties, before and after composting for approximately seven months using outdoor windrow composting methods, were determined using standard methods. Other quality parameters determined were C: N ratio, pH, density, odour, smell, color, enzymatic activity and temperature at maturity time. The results were compared using the one-way analysis of variance to confirm the suitability of sawdust for soil fertility management. The results revealed that non-lumbered wood fiber can be converted to higher-value product through composting to enhance soil fertility. The use of compost on a farmland has a various application. It remediates soils which are important to rural livelihood, reducing the need for chemical fertilizers and the amount of nutrient runoff. It is also environmentally friendly and controls environmental pollution. Sawdust is also put into judicious use when used as compost material.
