Stemflow influence on the distribution of soil (NaH/sub 2/PO/sub 4/ extractable) SO/sub 4/-S and pH was evaluated as a function of tree size class and distance from the stem for red maple (Acer rubrum L.) and scarlet oak (Quercus coccinea Muenchh.) at two locations in Tennessee which have received different historical inputs of S from atmospheric sources. Soil profiles around the base of each study tree were sampled by horizon at 25, 50, 100, and 200 cm from the stem along four transects radiating from the stem at 90/sup 0/ angles. Distance from the stem influenced soil pH of A horizons at 25 cm from the stem of red maple and scarlet oak at both sites. Species had an effect on Bt2 and Bt3 soil SO/sub 4/-S concentrations. The Bt2 (0.49 cmol kg/sup -1/) and Bt3 (0.67 cmol kg/sup -1/) horizons beneath scarlet oaks had greater SO/sub 4/-S concentrations than corresponding horizons beneath red maple (0.29 and 0.43 cmol kg/sup -1/, respectively). The results of this study indicate that increased sampling intensity combined with tracer studies will be need to clearly determine the effect of stemflow, tree species, and tree size on subtlety-manifested soil properties such as pH and SO/sub 4/-S as well as other elements of interest.
