Аннотация
A soil catena was studied on the Ergeni Upland; the soils and plants were sampled in five dependent points. The contents of macro- and microelements in them were determined. It was found that the radial (vertical) geochemical migration predominates in the eluvial positions of the catena, and the lateral geochemical migration predominates in the transeluvial and transeluvial–accumulative positions. Plants of the Poa L. genus intensely accumulated elements within the eluvial part of the catena, whereas plants of the Artemisia genus were element accumulators within the trans-superaquatic position. Plants of the Artemisia genus were generally characterized by a higher coefficient of the biological uptake of elements in all parts of the catena, except for the eluvial position, where this parameter was higher for plants from the Poa L genus. A rise in the magnetic susceptibility of the soil profile relative to the parent material was the highest in the eluvial position and the lowest in the trans-superaquatic position. A comparative analysis of geochemical ratios for modern soils showed that they are determined by the topographic position of the given point. However, the gradient of variations for surface soils is much smaller in comparison with that for buried soils indicative of the climatic fluctuations. The obtained geochemical indicators can be used for comparative analysis of buried soils found not only on the divides but also in the subordinate landscape positions.
