Table 3:

Comparison of 2022CROP relative change from 2002 results (Equation 3) to Wu et al. [7] scenario SII-4 and Deb et al. [49] scenario B1 results. 2022BASE results are summarized for Upper Mississippi River Basin (UMRB), Mississippi River Basin (MRB) and United States (US) domains. N export includes removal in surface and sub-surface losses in lateral flow. P export includes removal in surface runoff only. SII-4 and B1 values for all but evapotranspiration represent delivery to waterbodies. EPIC scenarios represent delivery to edge-of-field.
