As the ruinous Dust Bowl settled in the early 1940s, agronomist Edward Faulkner dropped what Nature magazine termed "an agricultural bombshell" when he blamed the then universally used moldboard plow for disastrous pillage of the soil. Faulkner's assault on the orthodoxy of his day will stimulate today's farmers to seek out fresh solutions to the problems that plague modern American agriculture. Plowman's Folly is bound together here with its companion volume A Second Look.
