FACTS is an ongoing project developed to forecast and evaluate in real-time soil-crop dynamics at  specific ISU research fields (field scale) and at regional scale. Predictions will be frequently updated as new information becomes available. The project investigators and Iowa State University are not responsible for extrapolations made by individuals to other fields.
