History and Mission

The Lon Mann Cotton Research Station is one of the three original branch stations established by the Arkansas Agriculture Experiment Station in 1926. Originally the Cotton Branch Station, it was renamed in 2005 to honor the legacy of Lon Mann who was a leader in the development of Arkansas agriculture.

The mission of the station is to serve the agriculture community, particularly those involved in agronomic crop production in eastern Arkansas. The 650 acre research station consists primarily of silt loam soils. Research includes annual evaluation of cotton, soybean, wheat, grain sorghum, and corn varieties and breeding lines as well as studies to determine optimum fertility, irrigation and pest management practices for these and other crops.

The station is also the site of the Eastern Arkansas Soil Testing and Research Laboratory, which provides statewide soil testing services.

Area farmers and business participated in a development campaign that concluded in 2005, which made possible major improvements to the Station. The Station Headquarters, which had been in the same building since 1926, is now in the Dan Felton, Jr., Building.

The new building includes a 160-seat auditorium, offices, lab, kitchen, and conference room. It is attached by a breezeway to the Soil Testing and Research Laboratory.

The Lon Mann Cotton Research Station is rich in the heritage of the Arkansas Delta. The staff and Project Leaders are highly motivated by a tradition of making the most of available resources to meet the needs of the Delta farmers for information to help solve problems and increase the profitability of agricultural enterprises.

The offices at the Lon Mann Cotton Research Station are open from 8:00 A.M. until 5:00 P.M. Monday through Friday. Friends and visitors are always welcome at the Station.
