Soil drainage and nitrate losses to surface waters: Insights from long-term SEPAC study

Part 3 of a 3-part series on a 35-year drainage study at the Southeast Purdue Agricultural Center in Butlerville, Indiana. Dr. Eileen Kladivko discusses drain spacing effects on the amount of water and nitrate-nitrogen leaving the field in drainflow, and the effects of cover crops on those losses.
