davis pacSize and Topography

  • 703 acres in northwestern Randolph and southwestern Jay Counties, including 522 tillable acres and 100 managed forested acres (known as the Herbert Davis Forestry Farm)
  • A variety of soil types but mostly fine-textured, heavy clay soils (Blount/Pewamo) commonly found in east central Indiana - gently rolling, hard to manage, poorly drained, low organic matter


The Davis-Purdue Agricultural Center Includes 523 tillable acres and 100 managed forested acres in Randolph and Jay Counties. Mrs. Martha F. Davis donated the original farm to  Purdue University in 1917 in memory of her son.
In 1926 forestry professor Burr N. Prentice painstakingly numbered, mapped, described, and tagged every tree at this location. His work, and the work of Purdue foresters after him, have made the Davis-Purdue Research Forest the largest and oldest mapped forest in North America, resulting in its designation as a Registered Natural Landmark.
