Nitrous oxide emissions from Corn Belt soils spike when soils freeze, thaw

Nitrous oxide may be much less abundant in the atmosphere than carbon dioxide, but as a greenhouse gas, it’s a doozy. With a potency 300 times greater than CO2, nitrous oxide’s warming potential, especially via agriculture, demands attention. Researchers are now answering the call. In a new study, they document an overlooked but crucial timeframe for nitrous oxide (N2O) emissions in U.S. Midwest agricultural systems: the non-growing season.
