Abstract

For forest sites situated on various basic rocks in the eastern parts of the Ore Mountains the total content of a greater number of trace elements in the mineral soil and A. horizon is reported. The values of the nutrient level K (eutrophic) correspond approximately to the "medium" contents in soils predominantly used for agricultural purposes. Brown earths over olivine-nephelinite, gneiss, and phyllite are richer in trace elements than podzols over quartz porphyry. But even in the case of brown earth rich in Cu and Zn and lying an olivine-nephelinite tolerable contents are not exceeded. The partially richer accumulation of Pb in the mineral soil of the Tharandt Forest is conditioned mainly by geological and petrographical factors and to a lesser degree by immissions. For spruce sites not influenced by short-distance immissions preliminary skeleton values for trace elements in the L-, F-, H-, and A-horizons are indicated. The humus profile of spruce sites is suitable for evaluating the anthropogenic accumulation of trace elements in Mittelgebirge landscapes.
