Cover Crops

Cover crops can be defined as: non-crash crop plants to bring about a benefit. The can add or capture nutrients, reduce pest pressure, conserve soil moisture, prevent erosion, reduce production costs, or enhance soil health to name a few. WSU Whatcom County Extension has an active research program evaluating new or novel uses of cover crops. We’ve included information from our research trials and from other sources.
