Ethanol producing plants as well as those plants under construction are shown along with the National Agricultural Statistics Service's (NASS) county estimates for corn for grain yield per harvested acre by county. Driven by growing ethanol demand, U.S. farmers planted over 15 percent more corn acres in 2007. The NASS Annual County Estimates Program provides for the collection of crop data through cooperative agreements with each state. NASS field offices set annual county estimates for crop acreage, yield, and production and submit them to headquarters for official dissemination.
