The amounts of total S, organic N, organic C, and HI‐reducible‐S obtained from Ap layers of 54 soils collected from five major soil zones in Saskatchewan varied considerably with location within any one zone. However, the mean C/S, N/S ratios and the percentage of total S as HI‐reducible S of the soil organic matter showed similar and consistent trends. The C/N/S ratios ranged from 58:6.4:1 in the arid Chernozemic Brown soils to 129:10.6:1 in the leached Grey Wooded soils. The percentage of total S as HI‐reducible was approximately 50% in the Chernozemic soils in contrast to 36% in the Grey Wooded soils.
