Název v původním jazyce

Emission of N2O and CO2, denitrification measurements and soil properties in red clover and ryegrass stands

Popis výsledku v původním jazyce

The relationships between the fluxes of nitrous oxide (N2O) and carbon dioxide (CO2), and their concentrations in the soil air, three different measures of potential denitrification, soil moisture, soil temperature and precipitation were investigated insoils from beneath ryegrass (Lolium multiflorum Lam.), red clover (Trifolium pratense L.) and mixture of ryegrass-red clover stands on a gleic cambisol. Investigations were carried out in order to test the hypothesis that the measure(s) of potential denitrification are good predictor(s) of N2O fluxes and thus may be used in empirical models of N2O emission. Potential denitrification characteristics used in this study involved (i) short-term denitrifying enzyme activity (DEA), (ii) long-term denitrification potential (DP), both determined in soils amended with nitrate and glucose, and (iii) denitrification rate (DR) measured using intact soil cores. Flux measurements were made using cylindrical chambers (intemal diameter 31 cm, volume 0.
