Next spring could bring record U.S. acreage planted to corn, according to Purdue University agricultural economist Chris Hurt. Expansion in the ethanol industry and more corn exports are driving demand and corn prices higher. Hurt says growing demand for corn could motivate U.S. farmers to increase corn planting to 88 million or 89 million acres in 2007, up 10 million acres from 2006. Hurt says he expects corn to replace other crops on some acreage, such as cotton in the South and sorghum on the Plains. Much of the increase in corn acreage will, however, come at the expense of soybeans, with some Midwestern growers likely to plant this year's corn fields back to corn rather than the usual corn-soybean rotation.
