The effect of reduced atmospheric deposition on soil and soil solution chemistry at a site subjected to long-term acidification, Nacetin, Czech Republic

摘要

During the 1990s the emissions of SO2 fell dramatically by about 90% in the Czech Republic; the measured throughfall deposition of sulphur to a spruce forest at Nacetin in the Ore Mts. decreased from almost 50 kg ha(-1) in 1994 to 15 kg ha(-1) in 2005. The throughfall flux of Ca decreased from 17 kg ha(-1) in 1994 to 9 kg ha(-1) in 2005; no change was observed for Mg. The deposition of nitrogen ranged between 15 and 30 kg ha(-1) with no statistically significant trend in the period 1994-2005.
