Rainbow, America's Country Store Belkorp Ag

Growing on a solid foundation of customer satisfaction.
Delivered by the local people you know.

Rainbow Ag is pleased to announce that Belkorp Ag, LLC (Belkorp Ag) has acquired the John Deere dealerships in Ukiah and Calistoga on March 1, 2013 from Rainbow Ag. The Rainbow Ag retail stores will continue to supply the area with lawn and garden equipment, irrigation, clothing, feed and supplies. The Mayfield family will continue to own and operate Rainbow Ag with locations in Ukiah and Lakeport.

According to Jim Mayfield, President of Rainbow Ag, “Rainbow Ag will continue to serve Lake and Mendocino Counties from our existing locations in Ukiah and Lakeport. Rainbow will miss our long association with John Deere, but Belkorp Ag will be a great steward of the John Deere customer relationships that we have worked hard to nurture and develop over the past 30 years.”
