The CALGOS cotton simulation model has been derived from GOSSYM - COMAX. Its main purpose is to make it more useful for conditions of cotton production under irrigation in the arid regions of the Western US.
CALGOS is a process-level simulator of the cotton plant, soil processes and the micro-environment. It assists the cotton grower by allowing him to predict the possible results of alternative decisions on irrigation, nitrogen application, and other management practices.
A user-friendly interface, operating from the Windows environment, allows editing of the input, running the simulation, and viewing the results as output files and graphics. The model is now available for assessment by research or extension specialists, as well as by cotton growers and farm advisors.
