    Microbial activity reflects soil conditions and degree of development. The aim of this study was to compare microbial properties of reclaimed and unreclaimed post-mining soil. Microbial biomass, microbial respiration, and cellulose decomposition were quantified in two chronosequences of post-mining sites located in the Sokolov brown-coal mining area. The first chronosequence consisted of five sites reclaimed with an alder plantation (Alnus glutinosa, Alnus incana), and the other consisted of five unreclaimed sites naturally colonized by local vegetation (especially Salix caprea, Betula pendula, Populus tremula). The spoil material of all the studied sites consisted of tertiary clays without any topsoil cover. Microbial respiration per unit of soil mass as well as per unit of soil area decreased as site age increased. Microbial biomass, whether expressed as a function of soil mass or area, increased with site age in both reclaimed and unreclaimed sites.
