| The Davis-Purdue Ag Center (DPAC) includes 460 tillable acres and 100 managed forested acres (Herbert Davis Forestry Farm) in Northwest Randolph County. Mrs. Martha F. Davis donated the original farm located on SR 1 north of Farmland, IN to to Purdue University in 1917 in memory of her son. In 1926, forestry professor Burr N. Prentice divided the 100 acres of the virgin Davis-Purdue Research Forest into 55 quadrats. With painstaking attention to detail, he numbered, mapped, described, and tagged every tree with a stem diameter larger than 4 inches. |  |
| In 1976 Purdue foresters relocated 46 of Prentice's original corner posts and again mapped the central 21 quadrats. Since 1976 researchers have followed change in diameter, growth, and mortality for each size class and species. Prentice's work and the work of Purdue foresters after him have made the Davis Research Forest the largest and oldest mapped forests in North America resulting in its designation as a Registered Natural Landmark. |  |
| Researchers from Agronomy, Agricultural and Biological Engineering, Botany and Plant Pathology, and Entomology study soil fertility, crop diseases, weed control, and insect problems in corn, soybeans, and wheat at DPAC. In recent years, researchers have begun many Site-Specific Agriculture studies involving the collection of data with a yield monitor as well as variable rate applications of phosphorus, potassium, and nitrogen. Intensive soil data have also been collected at DPAC. The soils at DPAC are typical of eastern Indiana and studies have been very useful to producers who deal with similar situations. |  |
