Differences in some chemical properties of soil under oak Quercus cerris (L.), cherry laurel Prunus lauroerasus (L.), and yew Taxus baccata (L.) woody plants in Arboretum Mlyňany were studied. Originally, oak-hornbeam forest was naturally present on studied area therefore soil under oak woods was taken as control variant. Obtained results showed, that changed type of vegetation distinctly influenced soil chemical characteristics. Studied profiles significantly (P = 0.01–0.05) differed in phosphorus and potassium contents, in pH H2O and hydrolytic acidity. Profiles differed highly significantly (P = 0.01–0.001) in percentage of hot water soluble (C sub(hws)) and oxidisable (C sub(L)) carbon of C sub(T), sorption capacity and pH KCl values. The highest contents of potassium and phosphorus were found in A horizon under each studied woods. We suppose that mentioned macronutrients come from decomposed litter. Significantly (P less than 0.001) the highest organic carbon content (C sub(T)) was found in A horizon under cherry laurel wood (C sub(T) = 26.51 g per kg), under oak (C sub(T) = 22.63 g per kg), and under yew wood it was 20.71 g per kg. Type of vegetation influenced also humus quality. Low humus quality (ratio HA/FA) confirmed, that mainly under yew and oak was high amount of aggressive fulvic acids.
