MPR’s Kathryn Herzog presents a Mainstreet Radio report on the lack of crop diversity on many modern Minnesota farms. Some farmers and agronomists are looking for ways to bring the diversity back.

Earlier this century, Minnesota's farm fields were a patchwork of color... an array of crops. After WWII came a push for US farmers to increase production. Many streamlined their operations and focused more on one or two cash crops. This shift has helped Minnesota's farmers compete in the global marketplace. But as a result, the Minnesota landscape has suffered a significant decrease in plant and animal diversity.
