Fig. 2: The frequency of N2O fluxes measured at three categories of fields.
From: High nitrous oxide emissions from temporary flooded depressions within croplands
a Example of a flooded field, which for the particular field represents about 0.2% of the entire field equal to the mean across Zealand during intensive fertilisation in March/April. b Histogram showing the frequency of mean N2O fluxes measured at three categories of fields: the central part of the flooded field with standing water, the rim area of the flooded part and the ambient field surrounding the flooded part.
