    This study focuses on the quantification of the impact of potentially eroded topsoil particles on the available watercourse P concentration. By using Freundlich isotherms, we found that the concentration of adsorbed/desorbed P (Q) by soil particles in water with specific soluble reactive phosphorus (SRP) concentrations are significantly correlated to PM3 (Q = a ∗ PM3 + b) and also to the degree of P saturation as measured by oxalate extraction (DPSox, Q=c ∗ DPSox + d). We derived equations useful for quantitatively predict P exchange between topsoil particles when potentially eroded into watercourse and the recipient water of either known or targeted P concentrations.
