Estimating soil phosphorus (P) sorption parameters, such as the sorption capacity (PSC) and the degree of phosphorus saturation (DPS), is important in order to evaluate the potential of P loss from soil to water. Generally, PSC is determined by short-term P sorption measurements or, in acidic soils, is taken to be alpha(Al(ox) + Fe(ox)), where Al(ox) and Fe(ox) represent the amounts of aluminum (Al) and iron (Fe) extracted by a single extraction of oxalate, and alpha is the scaling factor. Then, DPS is calculated as the percentage of already sorbed P, assumed to be the amount of P extracted from soil with the oxalate solution (P(ox)), to PSC. A sorption experiment was carried out over 180 days on twenty-four acidic soils from different countries of Europe, in order to estimate long-term soil P sorption capacity and DPS, and to investigate their relationships with short-term sorption (PSI24 h), and Al(ox) and Fe(ox). Soils presented a very wide range in PSC (19.1-284.3 mmol P sorbed kg-1 soil) and DPS (5.5-63.8%), with P sorption resulting strongly correlated with the sum of oxalate extractable Al and Fe (r = 0.996; p < 0.001). The slope (alpha of the regression equation between PSC and (Al(ox) + Fe(ox)) was 0.49, very close value to that (0.50) normally used by several researchers to indirectly calculate PSC from Al(ox) + Fe(ox) measurements. Sorption capacity determined after 180 days of soil-P equilibration was, on average, 2.71 times greater than the 24-h derived P sorption. However, a strong correlation was observed for the relationship between long-term P sorption and PSI24 h (r = 0.950; p < 0.001), which confirms that short-cut P sorption measures can be effectively used to estimate the P sorption capacity of soils with reasonable accuracy.
