Description: Atmospheric deposition has been recognized as a significant environmental problem for several decades, but its impact on forest ecosystems in North America remains controversial. In an effort to further elucidate the impacts of atmospheric deposition to forested watersheds in the Mid-Appalachian region, several related watershed studies have been initiated by the U.S. Forest Service in Parsons, WV over the past decade. One of the experiments involved doubling the annual ambient rate of N and S deposition by aerial application of ammonium sulfate to Watershed 9 which had previously been converted from low grade hardwoods to Japanese larch. We report here on the impacts of this treatment on soil and foliar chemistry, and height and diameter growth of the Japanese larch. Foliar samples were collected from treated and control trees and analyzed for Al, Ca, K, Mg, Mn, N, P and S. Soil sample analysis included Al, C, Ca, K, Mg, Mn, N and S. Treated soil had significantly greater exchangeable Al and Mn and significantly lower exchangeable Ca and Mg (α ≤ 0.05) compared to control soil. Treated larch had significantly higher (α ≤ 0.05) foliar N, Mn and Al concentrations and significantly lower (α ≤ 0.05) P and Mg concentrations. Height and diameter growth of treated larch were significantly (α ≤ 0.05) less. The reasons for these growth differences are as yet unclear, however, preliminary analysis indicated significant correlations with selected soil chemical variables, some of which have changed in response to the treatment.
