In the Pekelsky stream research catchment (Bohemian-Moravian Highland, Czech Republic), the chemistry of precipitation and soil water was studied in different types of forest stands (mature and young spruce and beech stands, clear-cut). Data from 1996 to 2008 showed that the average year fallout of protons decreased both in the stands and in the clear-cuts. In all research plots, decrease of the protone (H+) fallout in precipitation was registered. Within the research plots, decrease of SO42-, Ca2+, Mg2+, Al3+ and heavy metals fallout was recorded. On the other hand, NH4+, NO3-, Cl- showed disunited trends. In the water from humus horizon (O), element concentrations increased. Decomposition of the upper humus layer and organic material of the upper soil horizons releasing measured elements can be stimulated by increased soil temperature depending on high air temperature or after felling.
