Figure S1. Spatial distribution of APSRU soil reference sites (APSoil).

Figure S2. The range and density of fertilization rate in Australian croplands. The dataset was obtained from Australian Agricultural and Grazing Industries Survey (AAGIS). The surveys were conducted by Australian Bureau of Agricultural and Resource Economics and Sciences (ABARES) based on the ABARES zones. The total records of this dataset were 849.
