Research Abstract

Andosol subsoils derived from volcanic ash often contain large amounts of adsorbed sulfate. To elucidate the origin and mobility of the adsorbed sulfate, measurements were made on the vertical distribution of sulfate content in soil profiles and the stable isotope ratio of sulfate-S in soils sampled at different depths, together with desorption/elution characteristics and isotopic exchange properties of the adsorbed sulfate. The results demonstrate that sulfates accumulated in agricultural soils have been derived from fertilizers and have origins distinct from those in uncultivated soils, and that the fertilizer-derived sulfate has a relatively large mobility in soil profile, causing desorption and downward displacement of antecedently adsorbed other anions such as nitrate.
