Twelve soils with low-medium phosphorus (P) retention capacities were equilibrated for 3 months with soluble phosphate at a rate of 100 mg P kg-1 soil. The P sorption properties of these soils both with and without added P were studied, including equilibrium P concentration (EPCo), standard P requirement, soil P sorption capacity, maximum buffer capacity, and P sorption index. In general, the soils with no added P showed low values of all the above parameters.
