Fertilizer use in Chinese croplands contributes significantly to global emissions of ammonia, nitrous oxide, and nitric oxide, impacting climate change. A study estimated that in 2018, these emissions totaled 3.81 and 0.73 Tg N yr-1 from synthetic N fertilizer and manure, respectively. Nitrous oxide and nitric oxide emissions have been steadily increasing, while ammonia emissions have been declining. Regions like Central South and East China are hotspots for these emissions. Rice, maize, and vegetables are the top emitters. The global warming effect of nitrous oxide emissions outweighs the cooling effects of ammonia and nitric oxide emissions. This data can help improve global emission inventories and mitigation strategies.
