Abstract
Inputs of SO4(-2), total N, PO4(-3), K, Ca, and Mg via bulk precipitation, throughfall and stemflow have been investigated over a 3-year period at two forest study sites on the Cumberland Plateau of Tennessee. The Cross Creek Watershed located 19 km from the Widows Creek coal-fired power plant was used to represent inputs to a forest site in the immediate vicinity of a large emissions source. The Camp Branch Watershed having similar forest cover and soil types, but located in an area 99 and 76 km from the nearest major point sources, was used to represent inputs as a function of regional conditions. Location exhibited its greatest influence on stemflow inputs, with only PO4(-3) and K failing to exhibit a statistically significant (P=0.05) increase in stemflow input at Cross Creek relative to Camp Branch. Based on this evaluation most atmospheric contributions to bulk precipitation, throughfall, and stemflow elemental inputs appear to be of regional rather than local origin.
