Soil nitrite measurements have potential to estimate nitrous oxide emissions

Spatio-temporal fluctuations in soil N2O emissions are well documented, but it is difficult to predict the location of ‘hot spots’ and the timing of ‘hot moments’ of N2O emissions from agroecosystems with dynamic, heterogeneous soil environments. Although the soil nitrite (NO2−) concentration is a potential indicator of soil N2O production, it is seldom measured. This perspective paper explains the emerging methods for NO2− quantification with...
