Summary
Non linear relationships between c/x against c, and x against x/c at low equilibrium concentrations, were obtained for some Sierra Leone soils: where x = P sorbed, mg/ 100g; c = equilibrium P concentration, μmol/liter. A single point index correlated well with isotherm slope; one of the uses to which this index can be put was illustrated.
