The authors designed their assessment to include both the basic foundation needed by non-experts and the detailed information needed by experts. Their assessment includes background information on acidic deposition (Chap. 1), an in-depth discussion of the nature of soil acidity and ecosystem H(1+) budgets (Chap. 2), and a summary of rates of deposition in the Southeastern U.S. (Chap. 3). A discussion of the nature of forest soils in the region (Chap. 4) is followed by an overview of previous assessments of soil sensitivity to acidification (Chap. 5). The potential impacts of acidic deposition on forest nutrition are described in the context of the degree of current nutrient limitation on forest productivity (Chap. 6). The results of simulations with the MAGIC model provided evaluations of the likely sensitivity of a variety of soils representative of forest soils in the South (Chap. 7), as well as a test of soil sensitivity criteria. The authors' synthesis and recommendations for research (Chap. 8) also serve as an executive summary.
