Alum treatment of poultry litter: decomposition and nitrogen dynamics.
While the poultry industry is a major economic benefit to several areas in the USA, land application of poultry litter to recycle nutrients can lead to impaired surface and ground water quality. Amending poultry litter with alum [Al3(SO4)2 x 14H2O] has received considerable attention as a method of economically reducing ammonia volatilization in the poultry house and soluble phosphorus in runof...
متن کاملDiversity of shrub tree layer, leaf litter decomposition and N release in a Brazilian Cerrado under N, P and N plus P additions.
This study investigated changes in diversity of shrub-tree layer, leaf decomposition rates, nutrient release and soil NO fluxes of a Brazilian savanna (cerrado sensu stricto) under N, P and N plus P additions. Simultaneous addition of N and P affected density, dominance, richness and diversity patterns more significantly than addition of N or P separately. Leaf litter decomposition rates increa...
متن کاملStrategies to Modify Phosphorus (P) in Poultry Manure and Litter
Dietary strategies Meet but do not exceed bird P requirements. Dietary P originates primarily from plant and animal feedstuffs and from inorganic P supplements. Formulating nutritionists can make considerable impact when they provide enough available P to meet bird requirements yet control the urge to add significant amounts as an extra margin of safety. For example, the National Research Counc...
متن کاملN and P uptake by strawberry plants grown with composted poultry litter
Composted poultry litter (CPL) can be used for horticultural crops as a source of organic matter and stabilized N. Recent studies indicated that P was not stabilized by composting and that excess P could be released into the environment when CPL was applied to land on N-based plant requirements. This experiment determined the effect of CPL and fresh poultry litter (FPL) from two sources on leaf...
متن کاملThe impact of alum addition on organic P transformations in poultry litter and litter-amended soil.
Poultry litter treatment with alum (Al(2)(SO(4))(3) . 18H(2)O) lowers litter phosphorus (P) solubility and therefore can lower litter P release to runoff after land application. Lower P solubility in litter is generally attributed to aluminum-phosphate complex formation. However, recent studies suggest that alum additions to poultry litter may influence organic P mineralization. Therefore, alum...
