Description
  • 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.

  • Bylo sledováno široké spektrum půdně mikrobiálních parametrů na chronosequenci ploch zahrnující plochy 1-41 let staré. Akumulace organické hmoty v půdě během sukcese se zdá být hlavním parametrem ovlivňujícím změny půdních mikrobiálních parametrů. Druhým významným parametrem ovlivňujícím mikroflory byla změna mikrostruktury silně ovlivněná činností půdních živočichů. Většina mikrobiálních parametrů dosahovala nejvyšších hodnot ve středních stádiích sukcese, kdy nadložní humus můžeme charakterizovat jako přechod mezi typy moor-moder. Později s rozvojem žížal dochází k posunu směrem k mullu mírnému poklesu většiny mikrobiálních parametrů s výjimkou počtů bakterií, které stoupají. Celkově lze říci, že hodnoty mikrobiálních parametrů v 30-40 letých porostech byly porovnatelné s hodnotami v nepoškozených lesích. (cs)
