Short summary

Nitrous oxide (N₂O) is a powerful greenhouse gas mainly released from natural and agricultural soils. This study examines how global soil N₂O emissions changed from 1961 to 2020 and identifies key factors driving these changes using an ecological model. The findings highlight croplands as the largest source, with factors like fertilizer use and climate change enhancing emissions. Rising CO₂ levels, however, can partially mitigate N₂O emissions through increased plant nitrogen uptake.
