Global atmospheric N2O concentration has surged by more than 23% since the pre-industrial era, rising from 270 parts per billion (ppb) in 1750 to 336 ppb in 2022. Approximately two-thirds of these emissions come from nitrogen fertilizer-applied soils and natural soils. Key factors influencing N2O emissions include climate, soil properties, and agricultural practices.
