Phosphorus Dynamics in Broiler Litter-Amended Soils
Because land application of broiler litter is commonly made in the spring before cropping season and in the fall, it is essential to understand how environmental variations, such as temperature, affect the phosphorus (P) dynamics. A laboratory incubation study was conducted at Waste Management and Forage Research Unit, USDAARS with the objective of determining the effects of temperature and soi...
متن کاملPhosphorus speciation in manure-amended alkaline soils.
Two common manure storage practices are stockpiles and lagoons. The manure from stockpiles is applied to soils in solid form, while lagoon manure is applied as a liquid. Soil amendment with manure in any form introduces a significant amount of phosphorus (P) that exists in both organic and inorganic forms. However, little is known about P speciation in manure stored under different conditions, ...
متن کاملPHOSPHORUS MANAGEMENT Ligands and Phytase Hydrolysis of Organic Phosphorus in Soils Amended with Dairy Manure
tion of IP6 and other IPs in dairy manure are attributed to the protective effect of IP6 complexation with polyvaInformation about orthophosphate and organic phosphorus (P) lent cations that reduces dephosphorylation. As a result, desorption in soil amended with animal manure is needed because a build-up of P following repeated manure applications poses risks of substantial amounts of dietary I...
متن کاملEffect of poultry diet on phosphorus in runoff from soils amended with poultry manure and compost.
Phosphorus in runoff from fields where poultry litter is surface-applied is an environmental concern. We investigated the effect of adding phytase and reducing supplemental P in poultry diets and composting poultry manures, with and without Fe and Al amendments, on P in manures, composts, and runoff. We used four diets: normal (no phytase) with 0.4% supplemental P, normal + phytase, phytase + 0...
متن کاملPhosphorus leaching in soils amended with piggery effluent or lime residues from effluent treatment.
Phosphorus (P) in wastes from piggeries may contribute to the eutrophication of waterways if not disposed of appropriately. Phosphorus leaching, from three soils with different P sorption characteristics (two with low P retention and one with moderate P retention) when treated with piggery effluent (with or without struvite), was investigated using batch and leaching experiments. The leaching o...
