– Nitrous oxide (N2O) emissions from agriculture primarily come from the application of nitrogen fertilizers and the management of manure, which stimulates nitrifying and denitrifying bacteria in the soil. Rice cultivation often involves significant nitrogen fertilization.
– While other crops like cotton, sugarcane, and wheat contribute to N2O emissions (due to fertilization), they are not major sources of methane from the cultivation process itself, unlike flooded rice paddies.
