The Walter family has farmed in the Midwest since the 19th century and since the 1930s they’ve been on a 2,000-acre farm 60 miles west of Chicago. They grow corn for the commodity market, mostly yellow dent, a starchy type of field corn that accounts for about 95 percent of all corn grown in the United States. It’s in demand for animal feed as well as to make ethanol and high-fructose corn syrup.
