Mixed Crops

Caption

Researchers tested mixed-species cover crop stands such as this one to see if they could balance the nitrogen-fixing and nitrogen-scavenging capabilities of individual species. Individually, cover crop species excel at either reducing nitrogen leaching or increasing nitrogen supply to cash crops. But they fail to excel at both simultaneously.
