Understanding Changes in Raccoon River Nitrate

As Iowa farmers have planted more acres of corn to meet the demand driven by the corn-based ethanol industry, many models predicted that nitrate concentrations in Iowa streams would increase accordingly. However, recent IIHR research based on water monitoring and published in the Journal of Soil and Water Conservation casts doubt on these predictions.
