Abstract: It is an ordinary practice to cover the areas after brown-coal mining with natural topsoil cover (topsoiling). Topsoiling is removal one topsoil from agricultural land, forest or area with vegetation and excavating to another place with poor organic matter content or in our case the brown-coal mining dumpsite. Advantages of topsoiling include higher organic matter and greater available water-holding capacity and nutrient content. Content of potentially toxic elements is very low. Ammonia nitrate (NH4NO3) extraction, BCR sequential analysis and aqua regia determination were applied in this study to prove that the proportion of bioavailable forms of PTE in reclaimed soils is also low. Amounts of potentially toxic elements were compared between different types of reclamation: an agricultural shown higher value for Pb and Cd, forestry has only one contaminant -- Cd. The research shows that toxicity of soil is low and has no dangerous influence for agricultural application.
