CONSERVING OF THE RESOURCES
Physico-chemical properties of lignite mine reclaimed soil formed under 19 different tree species in Sokolov, Czech Republic
Coal mining was, and still is, a very important part of Czech national economy. Since 1957, it has been compulsory for organizations which have been granted mining permissions to carry out restoration procedures after the mining is finished. The aim of this research was to compare the physico-chemical properties of reclaimed mine soil of Antonin locality in the Sokolov mining basin, Czech Republic, which was experimentally afforested between 1968 and 1972. 5 undisturbed soil samples were taken from each of the 20 homogeneous stands (100 samples in total) composed of 19 various tree species (10 broadleaved and 9 coniferous) and bulk and specific density, porosity, water retention capacities, pH, soil oxidizable carbon (SOC) and total levels of N, C and S were determined and compared. In most cases, forming of soils with better overall physical and chemical properties was noticed under the broadleaved species.
