Ethanol has provided an economic boost for Iowa, according to a newspaper editorial board. The state continues to lead the U.S. in corn production, and farmers have seen the benefits of increased corn demand. "Iowa's corn yield for 2011 was estimated by the [U.S. Department of Agriculture] to be 2.36 billion bushels -- up 9 percent from 2010. According to the USDA, 14.1 million acres of farmland was planted with corn in 2011. That was 5 percent greater than in 2010," the board writes.
