Abstract

Minerotrophic peatlands or fen mires are characterized by anaerobic conditions and subsequently by a delayed litter decomposition. Therefore, in spite of their relatively small global area proportion (approx. 3%), peatlands constitute important sinks for carbon and nitrogen compounds with approx. 30% of the world's terrestric reserves. Degraded by substantial drainage or cultivation peatlands with changing water tables convert from CIN sinks to C/N sources, because of strongly increased C and N mineralization processes. It was shown that such degraded peatlands release high rates of the radiatively active trace gas nitrous oxide. The groundwater table, mineral- N fertilization, and stage of degradation are major factors affecting the nitrous oxide release. To give reasons for measures reducing nitrous oxide emission from peatlands, further studies are needed focussing, on e.g., the influence of weather or vegetation or derivations to give evidence for large-scale areas, respectively.
