Daisy: an open soil-crop-atmosphere system model

Daisy is a well tested dynamic model for simulation of water and nitrogen dynamics and crop growth in agro-ecosystems. The model aims at simulating water balance, nitrogen balance and losses, development in soil organic matter and crop growth and production in crop rotations under alternate management strategies. The software, which recently was rewritten, has been carefully designed to facilitate interaction with other models, either by replacing individual Daisy processes or by using Daisy as a part of a larger system, thus making Daisy an open software system.
