A Midwestern farm boy, radical artist, and environmentalist who's been known to don pink boas while tilling his fields, John Peterson defies categorization. He's a strong believer in biodynamic agriculture, a system that focuses on maintaining healthy land by using herbal remedies on the soil, fostering biodiversity on and around the fields, and treating the entire farm as a living organism.

Peterson is also the subject of the 2005 documentary movie "The Real Dirt on Farmer John." Shot over three decades, the film chronicles how Peterson turned his family's defunct corn and soybean fields into a successful organic vegetable farm that sells produce through a community-supported agriculture program (CSA).
