Extended Data Fig. 7: Spatial patterns of hotspots for soil Nr loss mitigation by enhanced-efficiency N fertilizers (EEFs) substitution.
From: Reducing soil nitrogen losses from fertilizer use in global maize and wheat production

Bivariate maps comparing the N input of grid cells (that is, N input rate multiply by harvest area) with NUE enhancement by EEFs substitution for maize (a) and wheat (b). The status groups were allocated using equal distributions. Regions with high N input and high NUE improving potential are regarded as hotspots for soil Nr loss mitigation by EEFs substitution.
