The greenhouse gas nitrous oxide (N2O) is a byproduct of two natural phases of the nitrogen cycle: nitrification and denitrification. These processes are stimulated by the addition of nitrogen fertilizers to crop lands. Therefore the increased use of nitrogen fertilizers by farmers may lead to increased concentrations of N2O in the atmosphere. Photo: Liquid fertilizer being applied to a field of wheat.
