Issue: The Iowa Nutrient Reduction Strategy (INRS) calls for cover crop implementation on over 12 million acres, which equates to every other field. Despite numerous environmental benefits associated with cover crops, many farmers are still hesitant to change their current production practices. Major barriers to introducing cover crops as a conservation practice include cost of implementation, yield drag, and knowledge.
Nitrogen management practice effect on tile drainage water quality.
Long-term N fertilization rate and crop rotation effect on corn and soybean production.
Modeling corn yield response to N rate.
Corn nitrogen rate response comparison between tilled and no-till systems.
Surrogate measurement methods for nitrate-N loss in tile drainage.
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.
