A Fairfield man is considering running for the post of Iowa's Agriculture Secretary. Francis Thicke is forming an exploratory committee to investigate the option. Thicke says he's considering his candidacy because he feels there are areas of agriculture that need to be further explored. Thicke says Iowa agriculture needs to be more sustainable. One example he offers is planting crops in between the corn and soybean rotations such as rye, which he says would help hold soil in place. Thicke is an organic dairy farmer, who has also served in the U-S Department of Agriculture. He says he hopes to know for sure whether or not he'll run for office by this summer.
