Description
Summary:[Display omitted] •P fractionation in poultry litter impacted soils identified intermediately available Pi as the dominant pool in 0–5 cm soils.•Surface soils had lower P sorption capacity and higher desorption potential compared to the soils in lower depths.•P saturation ratio (PSR) was strongly related to P sorption-desorption parameters.•PSR can be effectively used to predict P sorption-desorption parameters for Piedmont soil region.
