Southeast Purdue Agricultural Center (SEPAC)

Size and Topography

  • Largest of the PACs, with 2,430 acres located six miles east of North Vernon in Jennings County
  • A timber base of approximately 1,600 acres
  • A variety of soil types but primarily silt loam soils common in southeastern Indiana—hard to manage, poorly drained, low organic matter
  • Highly erosive soils with no-till farming practices used on most of the cropland


SEPAC was established in 1977, when the state of Indiana transferred 830 acres from the Department of Mental Health’s Muscatatuck State School to Purdue University. In 2005, the Department of Natural Resources transferred an additional 1,600 acres to Purdue. The center is distinctive i​n its history of conservation tillage, including no-till.​
