The Iowa Soybean Association (ISA) is the country's largest state soybean association and is governed by an elected volunteer board of 21 farmers. ISA develops policies and programs that help growers expand their profit opportunities, such as creating international marketing programs for U.S. soybeans, supporting the renewable fuels industry, and promoting the development and consumption of foods that contain soy. The association promotes environmentally sensitive production, such as no-till farming, nitrogen testing and the creation of environmental management systems for individual farmers. ISA also funds production research aimed at growing soybeans more efficiently and profitably. The organization strives to make soybean production a profitable, worthwhile and environmentally safe way to farm.
