Effect 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 extractability of soils amended with stockpiled and composted cattle manure.
Managing fertilizer applications to maintain soil P below environmentally unacceptable levels should consider the contribution of manure and synthetic fertilizer sources to soluble and extractable forms of P. Our objective was to evaluate soil and manure characteristics and application rates on P extractability in recently amended soils. Five soils of the U.S. southern High Plains were amended ...
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 کاملMANURE Mineralizable Carbon, Nitrogen, and Water-Extractable Phosphorus Release from Stockpiled and Composted Manure and Manure-Amended Soils
Much of land-applied manure is surface-broadcast or incorporated to a shallow depth of fields under crop Dissolved N and P transfer to runoff water may increase with residue and conservation tillage management because of surface applications and shallow soil incorporation of animal manure. Information is needed regarding water-extractable nutrient release the need to conserve stored soil water ...
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...
