Staring at a future of lower corn prices and higher inputs, Huegerich decided to experiment. Two years ago, he planted 320 acres of conventional corn and 1,700 with GMO corn. To his delight, the conventional fields yielded 15 to 30 more bushels per acre than the GMO fields, with a profit margin of up to $100 more per acre. And so in 2013, he upped the ante, ordering six varieties of conventional seeds for close to 750 acres and GMOs for his remaining acres.
