Sources and sinks of N2O in rewetted fens (A02)

• Subject Area: Soil Sciences
• Term: since 2025
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 531801029

We will systematically investigate N2O production and consumption at all experimental levels of WETSCAPES2.0. State-of-the-art instrumentation (isotope ratio mass spectrometry (IRMS), cavity ring-down spectroscopy (CRDS)) and a combination of natural abundance isotope mapping and dual-isotope tracer methods will allow us to quantify the sources and sinks of N2O and, together with other projects within Wetscapes 2.0, link them to peat and biomass production, microbial community composition and activity, production and consumption of other GHG, nutrient cycling, and water dynamics.
