Water addition, evaporation and water holding capacity of poultry litter.
Litter moisture content has been related to ammonia, dust and odour emissions as well as bird health and welfare. Improved understanding of the water holding properties of poultry litter as well as water additions to litter and evaporation from litter will contribute to improved litter moisture management during the meat chicken grow-out. The purpose of this paper is to demonstrate how manageme...
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...
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 کاملAlum 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 کاملProspects for phosphorus recovery from poultry litter.
Land disposal of poultry litter is an environmental concern often associated to excess phosphorus (P) in soils and potential water pollution in regions with intense poultry production. Although poultry litter can be moved off the farm and traded as fertilizer, its transportation becomes less economical with increasing distances from the farm. Thus, new litter management alternatives are needed ...
