This year, everyone's eyes will be following the progress in Iowa's corn fields. The nation's number-one corn state is gaining new attention as farmers are expected to significantly increase their acreage to take advantage of the boom in corn-based ethanol. Iowa's corn fields are one signal of the revolutionary changes coming to agriculture. It's exciting because agriculture drives Iowa's economy and can contribute even more in the bioeconomy--that vast potential for renewable solutions to our nation's food, feed, and energy needs.
