| Popis: | The composition of water-soluble macro- and microelements and anions has been studied in soils formed within a monolithic soil–geochemical catena. It has been shown that the carbon and nitrogen contents regularly increase from eluvial to accumulative landscapes parallel to their hydromorphism. The distribution of water-soluble forms of macro- and microelements is related to bioaccumulative processes and features of eluvial–illuvial differentiation of soils. The margins of the watershed depression are characterized by the combination of eluvial–illuvial differentiation and intensive lateral removal of elements in spring, which determines the maximal leaching of the top soil horizons. The data of the cluster analysis confirm that there is a correlation of soil genesis and location in the system of geochemical catena with the composition of water extracts. |
