Biodegradability and microbial activities during composting of poultry litter.
Poultry litter is composted to reduce odor and pathogens and to improve its quality as a soil amendment. Organic material, e.g., sawdust, is added to increase the C:N ratio to achieve optimum degradation of organic C and retention of N through microbial biomass formation. However, the relative biodegradabilities of the organic material in poultry litter and the amendment are usually not known. ...
متن کاملReducing nitrogen loss during poultry litter composting using biochar.
Poultry litter (PL) is a potentially underused fertilizer because it contains appreciable amounts of N, P, K, and micronutrients. However, treatments like composting to reduce potential pathogens, weed seeds, and odor often result in high losses of N through NH3 volatilization. Biochar (BC) has been shown to act as an absorber of NH3 and water-soluble NH4+ and might therefore reduce losses of N...
متن کاملEvaluation of In-Vessel Composting for Poultry Mortality
Finding a cost-effective alternative to rendering for the biosecure and environmentally sound disposal of poultry daily mortality was the focus of research conducted by the Virginia Department of Environmental Quality (DEQ) in cooperation with the United States Department of Agriculture (USDA), the Virginia Department of Agriculture and Consumer Services (VDACS), Cargill Turkey Products, Pilgri...
متن کاملSolubility Enhancement of Phosphorus from Rock Phosphate through Composting with Poultry Litter
Improving solubility of rock phosphate is critical for phosphorus (P) management in cropping. This experiment was conducted during 2010 to determine the P solubilized from rock phosphate (RP) through composting with fresh poultry litter (PL). The RP used in the experiment was collected from Hazara area of Khyber Pakhtunkhwa (KP) province, Pakistan. The treatments comprised of PL alone, PL+RP, a...
متن کاملEffect of chemical and microbial amendments on ammonia volatilization from composting poultry litter.
Research has shown that aluminum sulfate (alum) and phosphoric acid greatly reduce ammonia (NH3) volatilization from poultry litter; however, no studies have yet reported the effects of these amendments on field-scale composting of poultry litter. The objectives of this study were to (i) evaluate NH3 volatilization from composting litter by measuring both NH3 volatilization and changes in total...
