United Prairie was formed in 1996, when Unity Grain and Grand Prairie Cooperative combined their crop production divisions in order to serve their customers more efficiently. In 1997, Monticello Grain added their crop production division to United Prairie. At that point, United Prairie operated four retail locations in Illinois: Pierson, Ivesdale, White Heath, and Tolono. In 1998, Unity Grain, Bement Grain, and Cisco Co-op merged to form Topflight Grain. Then in 2009, Grand Prairie Cooperative merged with Jamaica Farmers Elevator and Fisher Farmers Grain & Coal to form Premier Cooperative. Today, Topflight Grain and Premier Cooperative own United Prairie.
