Worthington, Minn. (AP) Minnesota's corn crop may be larger than first thought, thanks to recent rains. Last month, the U.S. Agriculture Department estimated the state corn crop at a big 168 bushels an acre. But abundant rain and mild temperatures boosted the September forecast by 2 another bushels an acre, according to newly released USDA data. The national estimate jumped even more, up over 4 bushels an acre. The anticipated huge harvest has depressed corn prices to below the breakeven point. For Minnesota soybeans, the latest forecast is unchanged at 42 bushels an acre. But the national estimate increased more than a bushel an acre.
