The country's corn, soybean and wheat inventory fell steeply from last year, according to a report released Friday by the U.S. Department of Agriculture.
In its latest grain survey, the agency reported that as of Sept. 1, old corn stocks -- grain harvested last year -- totaled 988 million bushels, a decline of 12% from the same time last year. That is the lowest level since 2004.
Shortly after the survey was released, corn futures prices jumped by the 40-cent limit on the Chicago Mercantile Exchange on Friday, with delivery for December corn at $7.56 per bushel.
Prices were already high as the worst drought in decades has decimated the country's corn crop. In August, corn futures rose to a record high of $8.49 per bushel. But prices eased after the Midwest saw some rainfall.
