We work to determine what drives the large variability in NO3-N losses from agricultural fields across the state.
FACTS is an ongoing project developed to forecast and evaluate real-time soil-crop dynamics in specific ISU fields. Predictions and measurements will be frequently updated as new information becomes available during the growing season.
What we do:
Cover crops are an integral component of cropping systems because they grow in the fall and early spring - that is, times when the soil would not have a growing corn or soybean crop. At present, cover crops are grown to benefit soil quality and reduce nitrate loss. In the future, ongoing research at ISU promises to identify additional benefits such as weed suppression. Cover crop acres are growing exponentially.
