Název v původním jazyce

Chemical characteristics of soils and pore waters of three wetland sites dominated by Phragmites australis: relation to vegetation composition and reed performance

Popis výsledku v původním jazyce

Chemical characteristics of soils and soil pore waters, plant species composition and horizontal stand structure were investigated for three reed stands in the Trebon Basin (Czech Republic): Branna sand pit and two littoral stands of Rozmberk fishpond (Rozmberk East and Rozmberk West). Phragmites stands were expanding, stable and retreating at the three sites, respectively. The elemental soil composition (especially of C, N, P, and K) indicated the lowest trophic conditions at Branna, intermediate at Rozmberk East and the highest at Rozmberk West. This corresponded well also with concentrations of ammonium nitrogen, dissolved reactive phosphate and total phosphorus in the soil pore water. In contrast, Branna had by far the highest level of total nitrogen, determined by nitrate nitrogen (20 mg l(-1)), and the highest level of total dissolved solids (concentrations of NO3-, SO42-, Ca2+ and Mg2+) of all three sites. No conspicuous differences were found among the three stands in biomass a
