Environmental Policy Integrated Climate Model (EPIC)

Environmental Policy Integrated Climate (EPIC) model is a cropping systems model developed to estimate soil productivity as affected by erosion as part of the Soil and Water Resources Conservation Act analysis for 1985. EPIC simulates approximately eighty crops with one crop growth model using unique parameter values for each crop. It predicts effects of management decisions on soil, water, nutrient and pesticide movements, and their combined impact on soil loss, water quality, and crop yields for areas with homogeneous soils and management.
