ABSTRACT



The sorption complex of forest soils ensures the capability of pedons to adsorb exchangeable ions from soil solution and releases them mainly for interactions with plant roots. In this way it determines the physiologically utilisable trophic potential of the site. Its significance for biocoenose preservation on polluted localities increases mainly when it becomes the bearer of homeorhesis for ensuring of the succession processes. The present state (autumn 2002) of the effective and potential values of forest soil sorption complex basic characteristics and their momentary correlative relationships was studied in experimental substitute stands with varying tree-species composition in south-western part of the BroumovskŠ vrchovina Highlands (Czech Republic). The mean annual temperature and the average annual precipitation are 6.9 °C and 671 mm, respectively. Two volumetric samples were taken from Ferralic Cambisols. The stands were afforested at a homogenized ground by ploughing. Due to an absence of old organic surface layers and an artificial homogenisation, the remarkable effects of pure and mixed tree species stands were evaluated. The highest values of the measured elements and quantities were detected at H-horizons. Predominantly, the differentation of Ca2+ and Mg2+ content and base cation content (BCC) were observed and links to varying tree-species composition and humification were statistically evaluated. The total potential values of cation exchange capacity (CECp) were not significantly differenced by varying stand tree-species composition; it depends mainly on the quantity of protons (H+) inputs.

Key words: cation exchange capacity (CEC), sorption complex, soil, phytocoenose.
