The influence of topography on the nature and distribution of soil sulfur across a narrow environmental gradient.

Abstract

The nature and distribution of forms of sulfur within the soil profile was studied in a climo-toposequence of soils from Saskatchewan. Organic SO4= in the surface horizons, as a proportion of the total S, decreased from upper to lower slope positions and across a narrow environmental gradient going from the arid Brown Chernozemic soils in the southwest to the more humid Gray Luvisols in the northeast. -from Authors
