Managing N2O
Nitrous oxide (N₂O) is a potent greenhouse gas and ozone-depleting substance produced through microbial nitrogen transformations in agricultural soils. In potato systems, where high nitrogen inputs coincide with irrigation, soil conditions can favour nitrification and denitrification processes that drive N₂O emissions. This article outlines the mechanisms behind N₂O production and reviews management practices that can reduce emissions while maintaining crop performance.
