The state boasts a rich history of drainage related hydrologic and water quality research and educational activities. However, mineralization of high organic matter soils still contributes significantly to nitrate losses. To address agricultural issues related to increased flooding in recent years, Extension specialists and researchers are providing research-based information on design criteria, economic feasibility and environmental impacts of agricultural drainage to producers, drainage contractors, landowners, soil and water resource planners, and others.
Anecdotal evidence suggests that an even higher percentage of cropland is actually drained.
