DES MOINES, Iowa (AP) — Farmers attending the Iowa Power Farming Show next week in Des Moines will get a chance to learn about promoting soil conservation and health by planting cover crops. Cover crops are plants seeded on corn and soybean fields during the off season to help control weeds, prevent soil erosion, and promote soil health.

Iowa Secretary of Agriculture Bill Northey says the workshops hosted by Iowa Farm Bureau will help farmers find direction on choosing the right cover crop seeds, receive information on application and termination of cover crops, and learn more about how cover crops fit with a livestock operation.

The Iowa Power Farming Show runs Jan. 28 through 30 at Iowa Events Center. It is expected to draw 20,000 people to see the latest in farm equipment and technology.
