This paper deals with a specific type of homogeneous beechwood called Fageta paupera. The aim is to acquire information about the heterogeneity of soil environment. We used 20 research plots of semi-natural European beech stands where the sampling of soil profile and the observation of floristic conditions were realized. Laboratory assessment of soil samples was focused on physicochemical and chemical properties of soil: pH/CaCl2, K+, Ca2+, Mg2+, CEC (T, S, V), Cox, Nt, C/N, C-FA, C-HA, C-CHL, C-HA/FA. Data processing was done with the aim to discover a variability of soils, observing soil genetic horizons individually (H, A, B, C). Research plots were divided into biotopes with the cover of understory vegetation less than 15% and more than 15% (in accordance with the definition of Fageta paupera). The variability of soil properties in each horizon for the two above-mentioned biotopes and furthermore for all plots together was investigated. Our results show high variability of soil properties in the biotope of Fageta paupera, especially in its holorganic (H) and organomineral (A) horizons. Furthermore, regression analysis showed a strong dependence of the variability of soil properties in the biotope of Fageta paupera.
