Director Listing

ISA is governed by a board of volunteer farmer-directors elected by the state membership. Two directors are elected from each crop reporting district. Members also vote for four at-large directors. The 22 directors meet throughout the year to develop policies and programs.

Iowa also has six farmers who serve as national directors on the American Soybean Association’s board of directors, four who serve on the United Soybean Board and one farmer representative who serves on the National Biodiesel Board.
