(AREA) -- The U.S. Department of Agriculture's Prospective Plantings Report shows that corn growers intend to plant 97.3 million acres of corn for all purposes in 2013, up slightly from last year and 5.5 percent higher than in 2011. The report has a major impact on agricultural markets as it is widely used by commodity traders to find data on crops like corn, wheat, soybeans and cotton. Jim Zook, Executive Director of the Corn Marketing Program of Michigan, said the corn prospective plant estimates for this season are encouraging for growers, but that successful seasons always come down to if the weather cooperates or not. Zook said the report should cool the amount of heat the corn industry has been receiving from ethanol opponents who have been spreading misinformation about ethanol and how corn deficits have caused a rise in food and fuel costs. It also helps livestock producers, providing some relief to their increased feed costs.
