Great point mike.
That is on top of the nearly 1 million acres of lost production since 2007. We have gone from just over 93 million acres of corn planted in 2007 to around 91 million this year.
The percentage of the US corn crop going to ethanol is expected to exceed 50% in 2011. It was around 3% in 2006. Most of that was waste corn that would have been disposed of as unfit for normal uses.
