The compost will improve soil structure and increase its ability to hold moisture. Organic Soil Amendments We recommend using 100% worm castings as a top dressing. Worm castings are odorless and have the appearance of coffee grounds. They impart a slow release of nutrients to the soil, increase its water holding capacity and immunity to disease.
