Extended Data Fig. 1: Global cropland NH3 emissions mitigation potentials.
From: Fertilizer management for global ammonia emission reduction
Emissions maps of rice (a), wheat (b), and maize (c) at the country scale; the proportions of mitigation potentials to NH3 emissions under the best management scenario for rice (d), wheat (e), and maize (f). “No data” represents no planting of rice, wheat or maize. Map created using Python 3.8.
