Behind America’s dollar hamburgers and 72-ounce sodas is a key ingredient that quietly fuels our fast-food nation: corn. In KING CORN , recent college graduates Ian Cheney and Curt Ellis leave the east coast for rural Iowa, where they decide to grow an acre of the nation’s most powerful crop.
Alarmed by signs of America’s bulging waistlines, the filmmakers arrive in the Midwest enthusiastic about their new endeavor. For their farm-to-be, they choose a tiny town in Floyd, County, Iowa is a place that, coincidentally, both Ian and Curt,s great-grandfathers called home three generations ago. They lease an acre of land from a skeptical landlord, fill out a pile of paperwork to sign up for subsidies and discover the U.S. government will pay them 28 dollars for their acre. Ian and Curt start the spring by injecting ammonia fertilizer, which promises to increase crop production four-fold. Then it’s planting time. With a rented high-tech tractor, they set 31,000 seeds in the ground in just 18 minutes. Their corn has also been genetically modified for another yield-increasing characteristic: herbicide resistance. When the seedlings sprout from Iowaâ€™s black dirt, Ian and Curt apply a powerful herbicide to ensure that only their corn will thrive on their acre.
