I recently spent several hours driving through parts of Iowa away from the interstate. I begin to wonder exactly how much of Iowa was covered with corn.
Iowa is 55,869.36 squares miles in size. There are 640 acres in a square mile therefore Iowa contains 35,759,390.4 acres of land.
2007 they planted 14.3 million acres of corn in Iowa, the most in the nation. That means 39.9% of Iowa is covered with corn this time of year.
2007 they planted 8.8 million acres of soy beans or 24.6% of Iowa.
2007 they planted 2.5 million acres in hay (2 types) and oats or 7% of Iowa.
Between the 5 crops 71.5% of Iowa is covered with crops.
