Description	Během 90. let klesly v České republice dramaticky emise SO2 o 90%; podkorunová depozice ve smrkovém porostu na Načetíně v Krušných horách z 50 kg S ha(-1) v roce 1994 na 15 kg S ha(-1) v roce 2005. Hodnota pH půdního roztoku v hloubce 30 cm zůstala nezměněna, ale koncentrace Al klesla z 320 umol l(-1) v roce 1997 na 140 umol l(-1) v roce 2005. Od roku 2005 ustalo zcela vyplavování nitrátů z půdního roztoku v hloubce 30 cm. Z toho lze usuzovat, že vysoká mineralizace uložené organické hmoty po desetiletí atmosférické kyselé depozice může být důležitým faktorem ovlivňujícím vysoké ztráty dusíku ve smrkových ekosystémech. (cs) 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 pH of the soil solution at a depth of 30 cm, remains unchanged, and the Al concentration decreased from 320 mu mol l(-1) in 1997 to 140 mu mol l(-1) in 2005. Since 2005, the leaching of nitrate observed in soil solution at 30 cm depth has disappeared. It seems that high mineralization of stored organic matter after decades of high acidic deposition could be an important factor affecting the high losses of nitrogen in spruce forest ecosystems.
