Abstract
Lindebener L. (1990) compared chemical soil parameters between the stem foot area (near the base of a stem) and the area between the trees in 152 mature beech stands revealing significant impacts of atmospheric deposition: soil acidification, increased sulfur contents, loss of the base cations calcium and magnesium. Meanwhile, air regulations caused a marked reduction of SO2 emissions, the main precursor of Acid Rain. We propose to resample part of these forest sites to see, whether soils recovered from acid loads. This old story Acid Rain is a current issue again, since, depending on soil properties, release of historical deposited sulfur exceeds current inputs at several places, causing acidification of soil and surface waters.
