1. Phosphorus Sorption Behavior of Kentucky Soils with Varying Indigenous Phosphorus Content

The risk of phosphorus (P) losses from agricultural lands through surface transport to waterways increases with increasing levels of soil P. Agricultural soils in the Inner and Outer Bluegrass of Kentucky have high indigenous P content. This study investistigates the phsophorus sorption characteristics that influence the soils potential for P loss to water bodies. Four soils from the Inner Bluegrass and four soils from the Outer Bluegrass were identified as eing agriculturally significant soils not...
