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 کاملFeeding Poultry Litter to Ruminants
Experiments were conducted to assess the feasibility of recycling poultry litter in the diets of young calves. Weaning rations containing 30% ensiled or unprocessed poultry litter gave unsatisfactory growth when fed to calves from two to twelve weeks of age. However, when these twelve week old calves were fed rations containing 30% or 50% poultry litter and sorghum, the costs/kg. gain were 19.5...
