This paper reports the results of studies concerning phosphate sorption variability. Two kinds of soil populations were studied, a large soil population that includes most of the orders of Soil Taxonomy (British and tropical soils), and a less diverse collection of soil samples corresponding to four different soils series (three from Britain and one from Malaysia)

The variation in sorption index within soil series is usually considerably less than the variation in a more diverse collection of samples (British or tropical soils). Within a soil series the magnitude of the variation of phosphate sorption measured over large distances (different sites with uncultivated soils) is not much greater than values found over small distances. When comparing cultivated and uncultivated soils, we found that fertilizer treatments and liming appreciably reduce both phosphate sorption capacity and their heterogeneity
