  3. APEX, Agricultural Policy/Environmental eXtender model, was developed to extend EPIC’s capabilities of simulating management and land use impacts for whole farms and small watersheds. EPIC (Environmental Policy Integrated Climate model) is a cropping systems model that was developed to estimate soil productivity as affected by erosion.

  4. 2017年11月1日 · The APEX model is a farm- to small watershed-scale, daily time-step, process-based model that simulates daily water flux, plant growth, nutrient cycling, soil erosion, and nutrient loss (Williams and Izaurralde, 2006; Wang et al., 2009; Gassman et al., 2010; ; ).
