This study examined the effect of the soil water dynamics on N2O
emissions in repacked soil cores subjected to wetting-drying cycles.
High temporal resolution of the N2O measurements allowed capture
of a brief peak at the beginning of the soil drying. Its intensity was
large enough to affect cumulative N2O fluxes at the time scale of the experiment.
A similar peak dynamicswas observed for CO2, despite different
optimal moisture conditions for its formation, implying that a
physical process was responsible for the peak. Indeed, N2O and CO2
have been entrapped in the soil pore space and in the water phas
