The 1950's and 1960's saw the introduction of irrigation farming to the area. It was found that it was economically feasible to pump water to the surface from the vast Ogallala Formation located 200 to 400 feet below ground. The flat, nearly level land around Plains was ideally suited for irrigation. The early settlers would be amazed to see corn being produced around Plains with yields that they never dreamed of, as well as milo, soybeans, alfalfa, sunflowers, and many other diversified crops. The introduction of irrigation farming to the area stabilized the economy of Plains more than any other single event since the town was founded.
Agriculture is the primary industry of the area.
