Abstract
Nitrous oxide (N2O) emissions via the nitrification (I nit) and denitrification (I den) pathways were successfully measured with in-field incubation of soil cores in preserving jars at 0 Pa and 5–10 Pa acetylene. From the incubations, fractions of nitrification – N2O over total N2O (I nit / I tot) – and denitrification – N2O over total N2O (I den / I tot) – were obtained. Actual field emissions of N2O via nitrification (F nit) and denitrification (F den) were calculated by multiplying the fractions from the incubation technique with the daily N2O emission (F day) determined with a direct soil cover method. The approach presented here was successful for a whole range of soil moisture conditions in intensive grassland. F nit and F den followed the trends of soil ammonium and soil nitrate.
