Rodale Institute was the first farming organization to experiment and promote organic principles. Indeed, Rodale was the inventor of organic farming, insisting that the soil be nurtured and pests be fought without petroleum-based chemicals. On their Pennsylvania property, they try new and old experiments for row-cropping, vegetable farming, livestock maintenance and equipment innovation by using techniques they've perfected through the years. Now they are bringing their ideas to the midwest with a cooperative venture in Iowa. Kristine Lang talks to Margot McMillen about the work being done there and explains how midwestern farmers can get in touch and learn more.
