PHOSPHORUS MANAGEMENT Reduction of High Soil Test Phosphorus by Corn and Soybean Varieties
a significant relationship was found between soluble P loss in runoff and soil test P. Eghball and Gilley (2001) Soils with high levels of P can contribute to excess P in runoff and found that erosion was the most important factor in subsequently pollute the surface water. Excess P in the soil can be removed from the system by harvesting crops. The objectives of this loss of total and particula...
متن کاملPhosphorus Losses in Runoff after Application of Litter from Broilers Fed High-Available Phosphorus Corn Feed
Recent efforts to reduce phosphorus (P) content of corn grain fed to poultry have led to the development of low-phytic-acid corn. Research is needed to evaluate the environmental impact of the application to cropland of manure from animals fed low-phytic-acid corn. The purpose of this research was to determine P losses in runoff from a bare Piedmont soil (cecil clay loam; clayey, kaolinitic, th...
متن کاملGrowth Performance, Phosphorus Balance, and Bioavailability of Phosphorus in Pigs Fed High Available Phosphorus Corn and Phytase
Phytase has been shown to consistently improve the bioavailability of phytate phosphorus for pigs. However, only about 60 to 70% of the phytate P in a corn-soy diet is made available when supplemented with an optimal phytase dose. The use of high available P (HAP) should provide an additional strategy for improving the bioavailability of phytate P in pigs. In experiments 1 and 2, growth perform...

متن کاملSurface runoff losses of phosphorus from Virginia soils amended with turkey manure using phytase and high available phosphorus corn diets.
Many states have passed legislation that regulates agricultural P applications based on soil P levels and crop P uptake in an attempt to protect surface waters from nonpoint P inputs. Phytase enzyme and high available phosphorus (HAP) corn supplements to poultry feed are considered potential remedies to this problem because they can reduce total P concentrations in manure. However, less is know...
