Between 2000 and 2009, U.S. ethanol production increased from
1.6 billion gallons to 10.8 billion gallons, almost all of which
was produced from corn. While some of the corn came from increased
yields and some was diverted from other uses, much of the corn
needed to produce ethanol came from expanding planted acreage.
Between 2000 and 2009, U.S. corn production increased from 9.9
billion bushels grown on 72.4 million acres to 13.1 billion bushels
grown on 79.5 million acres. National-level data show that between
2006 and 2007, a large increase in corn acreage was accompanied by
a sizable decrease in soybean acreage, but this shift largely
reversed between 2007 and 2008. Over the long run, there is not an
obvious historical shift out of soybeans into corn. Both corn and
soybean acreage increased over the past decade. This chart comes
