The article illustrates to quantify the relationship between water soluble phosphorus (WSP) and Mehlich-3 phosphorous (M3P) in varied textural benchmark soils in North Carolina. This study also points to quantify the change in WSP concentrations which follows phosphorus additions to soils over a broad range of initial M3P. Soils with M3P were collected from loamy sand, muck loam, silt loam, and sandy clay loam. An incubation study of four soil samples representing a range in M3P from each series which were fertilized at different rates is conducted. Finally, the data indicates that shifting animal waste applications to fields of lower M3P concentrations would have a quick impact on reducing the risk for losses of phosphorus.
