By the numbers: Changes in corn planting by state

Corn Belt states have seen a sizable jump in the amount of land dedicated to corn. This boom has been fueled in part by a federal law requiring oil companies to add corn-based ethanol to the gasoline supply.
Here's a look at the change, in acreage planted to corn, in major corn states since 2006, the year before the ethanol mandate took effect.
