The primary commodities located in the Rolling Red Plains Area are wheat, range, and cattle. Other important commodities include grain sorghum, alfalfa, and cotton.

Size and Location

The station consists of 1,560 acres and is located 10 miles south and 5 miles west of Clinton or 5 miles west and 1.5 miles north of U.S. Highway 183, at Bessie, Oklahoma. The station is located slightly south of the north/south midpoint of the Rolling Red Plains Resource Area. The Rolling Red Plains extends from south of the Red River to north of the Oklahoma/Kansas border consisting of approximately 9.4 million acres, which occupies a significant portion of Western Oklahoma excluding the Oklahoma Panhandle.


This is a rolling upland prairie site consisting of a Cordell soil series. The site is predominately a shallow, somewhat excessively drained, moderately permeable soil that weathered from a hard siltstone under a cover of mid and short grasses. These soils are on hilltops, hillsides, and in swales and canyons on uplands with slopes from 1-15%. The average annual precipitation is 30.70 inches with an average summer high temperature of 93.6°F and average winter low temperature of 26.1°F.
