The continued low prices at the gas pump have Illinois corn farmers worried. The spot price for ethanol is down nearly 50-percent in the past two months to a point where ethanol producers may slash their output, meaning they'll be using less corn and corn prices could fall even farther than they already have. Farmers in Illinois and across the Midwest are facing a decision as they prepare to plant -- should they reduce the number of acres of corn and boost the number of acres of soybeans? Adding to the confusion is uncertainty about whether Washington will roll back its requirement for ethanol-blended gasoline.
