| Zusammenfassung |
| Microbial respiratory reduction of nitrous oxide (N2O)to dinitrogen (N2)via denitrification
plays a key role within the global N-cycle since it is the most important process for
converting reactive nitrogen back into inert molecular N2. However, due to methodological
constraints, we still lack a comprehensive, quantitative understanding of denitrification rates
and controlling factors across various ecosystems. In order to quantify N2-emissions
from terrestrial ecosystems we developed and applied a measuring system that
allows to simultaneously determine N2- and N2O-emissions from intact soil cores
with high accuracy (detection limit approx. 10 μg N m-2 h-1 for N2 and |
