WebJan 13, 2007 · The role of soil phosphorus (P) in the eutrophication of fresh water systems is well established. It is crucial therefore to assess the potential loss of P from soil in the various scenarios where soil can come into contact with water. To date, such assessment has often been based on soil P tests that are used for agronomic purposes (e.g. fertilizer … WebSep 7, 2015 · Phosphorus uptake did not depend on the amount of P in soil that was potentially available to plants, i.e., the classical “quantity” factor—which basically relates to Olsen P (Sánchez-Alcalá et al. 2014 ). Only the affinity factor of the Freundlich equation ( b) was a significant explanatory variable for both high- and low-P samples (Fig. 2 ).
