Garden with Insight v1.0 Help: Plant Growth

A single model is used in EPIC for simulating all the crops considered (corn, grain sorghum, wheat, barley, oats, sunflower, soybean, alfalfa, cotton, peanuts, potatoes, durham wheat, winter peas, faba beans, rapeseed, sugarcane, sorghum hay, range grass, rice, casava, lentils, and pine trees). Of course, each crop has unique values for the model parameters. EPIC is capable of simulating growth for both annual and perennial crops. Annual crops grow from planting to harvest date or until the accumulated heat units equal the potential heat units for the crop. Perennial crops maintain their root systems throughout the year, although they may be become dormant after frost. They start growing when the average daily air temperature exceeds their base temperature.

The plant growth submodels are:

Heat unit accumulation
Potential Biomass Increase
Leaf Area Index
Plant Size
Water Use
Loss of Senescent Plant Material
Winter Dormancy
