The Pine Tree Research Experiment Station of the University of Arkansas Division of Agriculture is located in east-central Arkansas approximately 50 miles due west of Memphis, TN. This station consists of approximately 12,000 acres of land, which includes 8,000 acres of timber or woodlands and 3,500 acres in cropland or otherwise open land.

The mission of the Pine Tree Branch Station involves crops research, foundation seed production, timber research, and wildlife management. Research on grain crops such as rice, wheat, soybeans, grain sorghum, and corn spans several disciplines including control or management of diseases, insects, and weeds; soil fertility; variety development; and crop management practices such as irrigation, row spacing, planting methods, and rotations.

Timber research is done in cooperation with the Arkansas Forest Resources Center located at the University of Arkansas at Monticello and includes stand management practices, regeneration techniques and alternative enterprises for East Arkansas Delta lands.

The Pine Tree Station works in concert with the Arkansas Game and Fish Commission and Division scientists to demonstrate improved wildlife management practices, including habitat improvement and species introduction.

Much of the station's time and resources are devoted to the production of foundation seed crops of rice, soybean and wheat for the Arkansas Crop Variety Improvement Program.

The soils and conditions of the Pine Tree location represent those of much of the crops producing region of Arkansas. Pine Tree Station is a major contributor to the success of the East Arkansas farming community.
