The topic of soil health and cover crops will be presented by Thomas Steger, of the U.S. Department of Agriculture's Natural Resources Conservation Service, at 7 p.m. Wednesday in the Courtyard Cafe at Red Wing High School.

The class, sponsored by Goodhue County Extension Master Gardeners and Red Wing Community Extension, will cover soil health, including discussions on "soil critters," recognizing healthy soil and the long-term ramifications of poor soil health.

Steger also will discuss the use of cover crops, mulch and plant diversity and how they can benefit soil health.

Soil glomalin effects on soil aggregation as well as soil stability and water infiltration will be demonstrated.

Admission is $5. To register, contact Red Wing Community Schools at 651-385-4565.
