 abstract={Miocene sediments, collected during brown coal excavation, have generally mechanical composition of loamy sand. The most negative feature of them is a very low pH-value, in a consequence of pyrite-oxidation. 20 years after technical reclamation and dump areas afforestation, a few conclusions about effects of the reclamation have been drawn:},
 abstract={1). The soil material in layer from 1 to 2 m deep is not homogenous. The layer from 0 to 20 cm is more homogenous as the result of mechanical cultivation before the sowing},
 abstract={2). After the slopes leveling intensive erosion processes have been occurred. About 25% of the total area has been damaged by water erosion. This effect should be connected with the absence of plant-cover},
 abstract={3). Soil-formation is related to anthropogenic activity, especially intensive liming, mineral fertilizing and afforestation. The influence of afforestation on soil is yet not very high. Clearly visible is a thin duff-layer (A0) ? about 1 cm},
 abstract={4). Nevertheless the heavy machines using during leveling, physical and water properties of the soils are quite good},
 abstract={5). The high lime doses causing rising the pH of top-soil-material (20-30 cm deep) to the value about 5-8. The soluble forms of Ca and Mg have been elevated considerably},
 abstract={6). The mineral fertilizing has caused an increase in the available forms of K and P},
 abstract={7). In the effect of waste lime use (from the smelting work) a distinct increase of the heavy metal content in the soil (especially Cu, Pb, Zn, Cd, Mn and Co) has been noted},
