Short summary
The consumption of the greenhouse gas nitrous oxide (N2O) by its reduction to dinitrogen via microbial denitrification in soil is poorly quantified. This precludes improvements in nitrogen (N) efficiency in agricultural ecosystems and mitigation of N losses to the environment including N2O fluxes. We present a laboratory evaluation for the determination of N2O reduction based on stable isotope values of soil-emitted N2O as a new approach to determine N2O reduction in the field studies.
