Iowa Corn’s Ben Gleason has an eye for water quality and soil conservation. “We encourage experimentation,” says Gleason, referring to trying sustainable practices on small areas before they’re used on the whole farm. He also pushes peer-to-peer knowledge exchange. “Farmers prefer to learn from farmers as far as what works in their area,” he says. Iowa Corn is one of many entities working toward the goal of soil and water preservation, according to Gleason. “Everyone has a role to play,” he says. “Everyone’s downstream from someone else.”
