Global N2Onet aims to cut farm nitrous oxide emissions with shared data

Nitrogen (N) fertilizer supports global agriculture, but its use and overuse drive emissions of nitrous oxide (N2O), a potent and long-lived trace gas. Incomplete understanding of N2O flux drivers makes it difficult to make spatiotemporal emissions predictions and evaluate management strategies for emissions reductions. N2O experts evaluated current sources of uncertainty and propose an initiative for accelerating advances in N2O measurement, analysis, and mitigation.
