Sulfur Speciation

Sulfur biogeochemistry of a northern hardwood forest soil in Bear Brook Watershed, Maine, was studied utilizing 35S in situ. The objectives of study were to characterize different S pools, their vertical distribution, and seasonal variation. Soil cores were used at the field and treated with 35SO42−. The distribution of total and C-bonded S followed a typical pattern of decreasing concentration with soil depth. More than 86% of total 35S added was retained by the soil. Most of the 35S activity was in the organic S pool (up to 73 and 20% of total 35S in C-bonded S and ester-sulfate forms, respectively) in both the forest floor and the mineral soil horizons. Ester sulfate increased with depth from 5.3 to 25.5% of total S. During the summer the relative importance of mineralization to immobilization decreased. Inorganic sulfate was the smallest S pool. However, higher specific activity and turnover rate of the inorganic 35SO42− pool than organic 35S pool indicated that S concentration and solution flux were more regulated by abiotic (adsorption and desorption) than biotic (mineralization and immobilization) processes.

Abstract Bulk density, oxygen, and temperature of a northern hardwood forest soil in Vermont were measured immediately before and for 2 years following harvesting using conventional clearcut and whole-tree removal methods. Bulk density increased (P ≤ 0.10) as a result of harvesting, but there was no difference between the two harvest methods. Increases were relatively small, and essentially disappeared within 2 years. Soil oxygen was never significantly affected by treatment. Soils in uncut (control) plots were warmer in winter and cooler in summer than those of either harvest area, but these differences appear to be diminishing with establishment of vegetation cover on the harvested plots.
