Aktuální pedologická problematika rekultivovaných lokalit oblasti Severočeských dolů a.s. / Current pedological issues of reclaimed sites of the North Bohemian Mines

The Brown Coal Research Institute has long term cooperation with the Severočeské doly a.s. (North Bohemian Mines) in the field of restoration problems. The target of this cooperation was mainly necessity of the application of the fertilizable soils. At present, the main problems appear to be the extreme alkaline soil reaction of any locality soils, the occurrence of phytotoxic and sterile areas and the methodology of setting up areas left to natural succession. The attention is also devoted to the loss of seedlings caused by dry periods. The article deals with the methodology of the survey, with the localisation of different individual types of areas, characterization of differences between Bílina mine and Nástup Tušimice mine areas and the optimal methodology for the restoration of the areas of interest.This publication was created within the project TEXMIN (The impact of extreme weather events on mining operations) co-financed by the European Union (EU) within the scope of the Research Fund for Coal and Steel (RFCS) under Grant Agreement 847250
