United Suppliers Inc., an Ames-based crop nutrient company, has purchased the assets of Evans Enterprises LLC, an ammonium chloride fertilizer business based in Olathe, Kan. The business includes patented technology used in fertilizer products that provide both nitrogen and chloride to cereal-grain crops, including corn, grain sorghum and wheat. These products are most frequently used on crops grown in the western U.S. to increase their yield potential. The technology will align with United Suppliers’ existing crop nutrient offerings to meet the specific needs of growers in the Great Plains looking to increase yields and profits, company officials said in a release. Current Evans Enterprises employees will join the United Suppliers team and operations are expected to continue uninterrupted, with United Suppliers taking over day-to-day operations effective immediately. United Suppliers is owned by a network of over 550 locally owned and operated agricultural retailers.
