Evaluation of acidic atmospheric deposition and its influence on soil solution composition in the Daniel Boone National Forest

The purpose of this proposal is three-fold: 1.) To re-measure the two sites in the Barton et al. (2002) study in the DBNF to determine if, over 12 years, there has been a significant change in the soil and soil solution chemistry resulting from atmospheric deposition, 2.) To determine the pattern of change, and 3.) Using additional data from tree cores and historical precipitation data, to determine if there are correlations between the soil and soil solution chemistry in the DBNF, forest productivity in the DBNF, and long-term precipitation data from nearby Robinson Forest.
