A sustainable-ag champion gets plowed under at Iowa State

Composting is nothing new at Iowa State University’s Leopold Center for Sustainable Agriculture, but throwing the director out on the compost heap is. After five years as head of the center, sustainable-ag champion Fred Kirschenmann was unceremoniously replaced last week, with two days notice. That stinks almost as bad as the huge corporate hog feedlots that increasingly dominate the state’s landscape, writes blogger Tom Philpott in Gristmill. Could the surprise move have something to do with agribusiness contributions to the university’s College of Agriculture?
