Movement of sulfate (S) through repacked columns of soil with high and low S adsorption capacity was studied in the laboratory. Differences in movement could be explained by the shape of adsorption isotherms which were determined from batch-type experiments. 34S was found to be a suitable tracer to study the movement of applied 32S. After leaching of a pulse of S added to the surface soil, the observed S ditributions in soil columns were not well described by theory. The discrepancies were largest when the soil containing the added pulse of S was incubated prior to leaching. Possible reasons for this lack of agreement are discussed.-from Authors
