Short summary
Denitrification is a key process in the soil nitrogen cycle but poorly investigated due to methodical limitations. The 15N gas flux method is currently the only approach allowing field measurement of denitrification but was subject to bias due to unaccounted fluxes of 15N-labelled gaseous denitrification products to the subsoil. We used field flux experiments and diffusion–reaction modelling to estimate this source of error and developed an approach to correct denitrification rates.
