The impact of introduced and indigenous woody plants on change of selected soil chemical properties in the Arboretum Mlyňany.
In this work has been studied the impact of changed vegetation on selected soil chemical characteristics of Stagni-Haplic Luvisol in the Arboretum Mlyňany. Soil samples from A horizons were collected under growths of anthropogenically introduced (Prunus lauroerasus and Pinus Jeffreyi) and indigenous (Picea abies, Taxus baccata, Quercus cerris and Carpinus betulus) tree species. Since the original vegetation in Arboretum was Querceto-Carpinteum forest, the soil under rest of that forest was used as control. Obtained results suggest that anthropogenic change of vegetation highly significantly affected the soil chemizm in A horizons under both, indigenous and introduced tree species. Prunus lauroerasus and Pinus Jeffreyi (their litter, root exudates) had the most significant effect on changes of studied soil chemical properties compared to the soil under original Querceto-Carpinteum forest. The most affected were values of sum of base cations, base saturation, content of available phosphorus and exchangeable aluminum.
