Phosphate Reactivity in Long-Term Manure Amended Soils in the Ridge and Valley of Virginia
… solution P concentration and the release rate of P from soil. Models relating soil test P (STP) to water soluble P (WSP) and the degree of P saturation (DPS) to STP are used in Virginia to estimate P loss potential. Typically the reservoir of biologically available P in eastern soils has been …

Effect of Synthetic Chelating Agent Application to Soils on Phosphorus Availability
… unavailable to crops due to immobilization of P in acidic soils through forming chemical bonds with iron (Fe) and aluminum (Al) amorphous oxides. Organic chelating agents form strong bonds with metals in soil and may reduce P binding with Fe and Al. Ethylenediamine tetraacetic acid (EDTA), …

Predicting the effect of wetland restoration on phosphorus retention, Northwest Minnesota
… soluble P is transported either within or out of the watershed. Soil analyses indicated that the site contains mineral soils that are Ca-rich. A phosphorus sorption index (PSI) was used to determine the degree of P soil saturation. The mean PSI was 24.7, indicating that the soils at the site …
