With WOFOST, you can calculate attainable crop production, biomass, water use, etc. for a location given knowledge about soil type, crop type, weather data and crop management factors (e.g. sowing date). WOFOST has been used by many researchers over the World and has been applied for many crops over a large range of climatic and management conditions. Moreover, WOFOST is implemented in the Crop Growth Monitoring System which is used operationally to monitor arable crops in Europe and to make crop yield forecasts for the current growing season.

1. Daily weather variables (temperature, radiation, precipitation, humidity, windspeed)

|Describe output parameters=WOFOST simulates the growth of a specific crop, given the selected soil and weather data. Crop growth is simulated using daily weather data of many years and different parameters for each relevant soil type within a region. If required for a particular study, calculated values, e.g. yields, biomasses produced or water use, can be averaged over the simulated years or aggregated over soil types.
The older Fortran implementations of the model require ASCII input files in the so-called CABO format.
|Describe output parameters=WOFOST simulates the growth of a specific crop and its interaction with the soil.

Further, the interaction with the soil is included in relation to soil moisture availability and (in more recent version) also soil N/P/K availability.
