After months of falling prices, corn rallied after the government reduced its estimate for the size of 2013's crop, and lowered its projection for corn supplies. The price of the grain has slumped since last spring when the U.S. Department of Agriculture first projected that farmers would produce a record harvest. (AP Photo/Dave Weaver)
