A research was conducted in the Jizerske hory Mts., Czech Republic, (altitude 880 m, acidic spruce forest site type - 8K) to evaluate the impact of Picea pungens and Calamagrostis villosa cover on the quantity and quality of upper soil layers. Mean weight of dry matter of holorganic horizons was similar under both variants. Totally, there were 153 t/ha of dry matter of humus horizons accumulated in blue spruce stands and 174 t/ha in reed stands. Soil pH (KCl) varied from 3.7 to 3.2 under blue spruce trees and from 3.6 to 3.3 under reed plants. The differences in nutrient concentrations (P, K, Ca, Mg) were not significant. Only the L horizon showed significant differences: there were higher values of cation exchangeable capacity and higher content of exchangeable bases under reed. Forest-floor humus properties were similar under both species studied. In conclusion, soil conditions under blue spruce were not significantly worse than those under reed plants.
