The aim is to acquire information about the heterogeneity of soil environment. As a material 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 15 and 15 in accordance with the definition of Fageta paupera and the variability of soil properties in each horizon for the two above-mentioned biotopes and furthermore for all plots together was investigated. Results show the highest variability of soil properties in the biotope of Fageta paupera especially in its holorganic H and organomineral A horizons. Furthermore regression analysis showed the strongest dependence of the variability of soil properties in the biotope of Fageta paupera. Keywords Fageta paupera soil variability of soil properties European beech Fagus sylvatica L. belongs to tree species with the complicated creation of forest communities. One of several factors causing this fact is the wide ecological valence of conditions in which beech is able to grow and a high aptitude of competition. Naturally it is not dominating vert over all forest area of its widespread. .
