Model description

A process-level whole farm simulation that includes alfalfa, grass, corn, small grain and soybean modules. Crop simulation is linked to establishment, harvest, storage, animal utilization and economic routines. Simulations predict performance, economics and environmental impacts of farms over many years of daily weather.
