Repercussion of Controlled Decomposition Process on Carbon Dynamics and Quality Evaluation in Chicken Manure Pellets

An incubation experiment was conducted to determine the decomposition potential of the chicken manure pellets and to know the nutrient composition. The chicken manure pellets produced from the bedding material of commercially grown broiler farm was tested for decomposition rate through CO2 evolution and nutrient content. The rate of decomposition of poultry manure pellets (CO2 emission) was less during the first week of incubation and linearly enhanced during 2nd and 3rd week after incubation. The rate of emission of CO2 has been reached maximum (150 mg of CO2 per gram per day during the 4th week of incubation. The enhanced CO₂ evolution indicated addition of more organic matter content and balanced steady release of nutrients on incorporation in to soil.
