The Illinois Nutrient Loss Reduction Podcast

The Illinois Nutrient Loss Reduction podcast explores efforts to reduce nutrients in Illinois waterways from agricultural runoff to municipal wastewater with host Todd Gleason and producers Rachel Curry, Nicole Haverback and Luke Zwilling with University of Illinois Extension.

This episode of the Illinois Nutrient Loss Reduction Podcast examines the crucial role of timing in cover crop establishment through discussions with regional farmers Adam Dahmer, Brent Fowler, and Greg Thoren. The speakers emphasize that optimal seeding dates depend on geographic location and operational goals, highlighting tools such as the Midwest Cover Crops Council's county-specific seeding charts. The panel explains the biological mechanics of fall planting, where autumn-seeded crops enter survival mode to establish subsurface root systems below the frost line rather than producing top growth. They detail management strategies for various conditions, including adapting to late harvests, utilizing aerial seeding, combining cereal rye and winter wheat with oats or legumes for winter protection and soil health, and accounting for local weather challenges. * Adam Dahmer, Williamson County, Illinois Farmer  * Greg Thoren, Jo Davies County, Illinois Farmer * Brent Fowler, McDonough County, Illinois Farmer
