Abstract: A system and a method for providing farmers/producers with crop characteristic predictions for standing crops located in fields includes a central database for storing field and crop information for the crops. A weather data processor receives raw weather data from either or both of (1) a weather data service with collected weather data from a plurality of weather stations; and (2) one or more site-specific weather stations associated with a particular field whose information is in the database. The raw weather data are processed to obtain field weather parameters for entry into a crop characteristic prediction equation, and the parameters are stored in the central database. With a user interface, a crop whose information is stored in the central database is selected.
