Drainage for the long haul: Key takeaways from the SEPAC study 
June 2020
​Subsurface "tile" drainage is an essential agricultural water management practice on naturally poorly drained soils. This publication presents a brief synopsis of key takeaways from a 35-year study at the Southeast Purdue Agricultural Center (SEPAC). More detailed discussions are provided in a series of three publications, AY-397-W, AY-398-W, and AY- 399-W.
​AY-396-W
Soil drainage and crop yields: Insights from long-term SEPAC study
June 2020
​This is Part 1 of a 3-part series on a 35-year drainage study at the Southeast Purdue Agricultural Center in Butlerville, Indiana. Dr. Eileen Kladivko discusses cash crop establishment and yield as affected by drain spacing.
​AY-397-W
​Soil drainage impacts on cover crop growth and soil improvement: Insights from long-term SEPAC study
June 2020
​Part 2 of a 3-part series on a 35-year drainage study at the Southeast Purdue Agricultural Center in Butlerville, Indiana. Dr. Eileen Kladivko discusses the effects of drainage on cover crop growth and the effectiveness of other conservation practices on improving crop growth and soil properties.
​AY-398-W
Soil drainage and nitrate losses to surface waters: Insights from long-term SEPAC study
June 2020
​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.
