ABSTRACT

Composting is a sustainable way of returning nutrients back in the soil. A laboratory composting study using a soda bottle was conducted to determine the effect of uncharred and charred poultry litter on the decomposition of compost. Organic waste materials consist of Arachis pintoi, wood chips, paper strips, banana peelings and goat manure were placed in a soda bottle for composting with soil mixed with uncharred and charred poultry litter. There were three treatments (control or no poultry litter application, applied with poultry litter and charred poultry litter) replicated three times arranged in completely randomized design (CRD). Results showed that highest microbial respiration was attained in compost without poultry litter and with the highest percent of weight loss. This implies that, poultry litter component did affect the activity of microorganisms in the decomposition process. Organic wastes amended with charred poultry litter have the lowest microbial respiration and percent weight loss. Microbial respiration was not significantly affected with the use of charred poultry litter compared with the uncharred poultry litter.
