The Iowa Promotion Board includes Iowa corn growers, elected by their peers, who direct funds collected through the Iowa corn checkoff program. The ICPB invests checkoff dollars in research, market development, and education about corn and corn products, to help defend and extend markets for Iowa corn growers. Established by a grower referendum in 1977 and continuing to add value for Iowa’s corn farmers today, the Iowa Corn checkoff has served as a model for many other states across the country.
