Summary Dihydrogen phosphate ion activity (H2PO4) and phosphate potential were measured in the saturation extracts of 14 representative Red Mediterranean soils (Alfisols) of Greece, estimating the ionic strength from a) measured ionic concentrations b) actual ionic concentrations and c) electrical conductivity measurements. The values of (H2PO4) and phosphate potential thus obtained were correlated with P-uptake by rye-grass in a pot experiment. The correlation coefficients did not differ significantly (p≤0.001) from one another and from those of (H2PO4) and phosphate potential measured in 0.01M CaCl2 extracts.
