Název v původním jazyce

Short term effects of experimental eutrophication on carbon and nitrogen cycling in two types of wet grassland

Popis výsledku v původním jazyce

Plant biomass production, soil chemical and microbial parameters, microbial processes of C and N cycle and gases emissions were studied in soils at two types of grasslands (wet meadows). Both sites are situated in the Czech Republic: (1) a nutrient poorsedge meadow on organic soil (Z) and (2) a mesotrophic sedge-sweet grass meadow on mineral soil (H). Eutrophication was simulated by the application of NPK fertilizer to selected permanent plots in 2006 and 2007 in amounts of 9 kg N + 4 kg P ha -1 year-1(low dose) and 45 kg N + 20 kg P ha-1 year-1 (high dose). After two years of fertilizer application, we observed an increase in net aboveground plant production (about 9-12 kg ha-1 year-1) connected with an increase in shoot:root ratio in fertilized plots of both sites, with more pronounced changes in oligotrophic sedge meadow. Total CO2 efflux from the ecosystem measured in situ was significantly higher at fertilized plots as well as increase in total soil respiration in case of sedgeme
