Every once in a while we see a piece of data which makes the hair on our heads stand on end. Such is the Census Foreign Trade graph of the month. Below are corn exports and their percent change a year from June 2012.

The more orange a state is, the more their exports declined. Texas corn exports declined a whopping -272.6%, Kansas dropped -160.9%. Arkansas is a real disaster, with a -445.2% drop in corn exports as of June 2012. What's worse is the June data only gives a 10% national drop in corn exports from a year ago. July gave much worse figures.

By July 2012, the United States corn export decline was the lowest in 19 years and had dropped 40% from a year ago according to the latest USDA statistics. The U.S. is the largest exporter of corn and corn is the largest export of course-grains. The below charts are from the USDA grain report.
