Anotace
A wide spectrum of soil microbial parameters (microbial biomass, respiration, direct counts of bacterial, fungal mycelium length, cellulose decomposition and FDA activity) was studied in the chronosequence of 1- to 41-year-old plots of spontaneous succession on post-mining sites near the town of Sokolov. At these sites, soil chemical properties and the role of humus micromorphology (driven by soil fauna activity) were recorded, and their relation to changes in microbial properties was evaluated. Growth of herbs and grasses occurred only occasionally on 3- to 14-year-old plots. Shrubs (Salix caprea) covered a plot 15-25 years old, and 26- to 41-year-old plots were forested mainly with Populus tremuloides and Betula spp. Organic matter content increased, while pH decreased during succession. Organic matter accumulation seems to be the main factor affecting the development of the soil microbial community.
