Abstract
Sulphate movement through two contrasting soils under various water regimes was studied in the laboratory. In both soils the downward movement of K2SO4 labelled with S35 applied on the surface increased with increasing amount of water applied. However, in one soil of volcanic origin, Montreal sandy loam (an Andept, Inceptisol) with high organic matter content, most of the sulphate was retained in the top 15 cm even under 20 cm of applied water. In the other soil, Montserrat clay (a Mollisol derived from glauconitic sandstone), with this amount of added water SO4 accumulated in the lower end of the column (45 cm) and some appeared in the leachate in spite of the high content of free Fe2O3 and Al2O3. Differences in the extent of sulphate movement in the two soils was accounted for by the differences in their properties which affect sulphate retention. re]19730410
