Dekompozice dřeva v horských temperátních lesích a jeho dopad na pedogenezi

This thesis deals with the monitoring of the impact of decaying wood on the soil characteristics and the related development of the soil profile. The subject of the research is the soils in the Žofínský prales National Nature Reserve in Novohradské mountains, with the predominant European Beech (Fagus sylvatica L.). Samples taken under the decaying stems are compared with the control samples of soils with the predominant leaf layer on the surface. In the soil beneath the beech stems, a significantly higher carbon content, higher pH, higher nutrient concentrations, lower exchange acidity, and mostly lower Al and Fe content were found. Decaying wood most affected the horizon A, more intense podzolization was not detected unambiguously
