Illinois Drainage Research and Outreach Program (I-DROP) – Ten Ways to Reduce Nitrogen Loads from Drained Cropland in the Midwest
The IDROP Ten Ways strategies include in-field cropping and management strategies (i.e., practices that reduce nitrate in the root zone), in-field strategies that modify the drainage system (i.e., practices that reduce delivery of nitrate to the field’s edge), and edge-of-field strategies (i.e., practices that remove nitrate at the edge of the field or downstream).
