K+S Group, Kassel, Germany, and Koch Fertilizer, Wichita, said May 22 that they have mutually agreed to terminate their exclusive marketing agreement. Koch was to market potash from the K+S Bethune plant in Saskatchewan into the U.S.
K+S says it will utilize its own marketing team in North America to maximize the value-chain for deliveries from their Bethune mine and are currently testing the supply-chain processes.
