How does compost improve water quality?

Compost can improve water quality in a variety of ways. It can improve the biological, chemical, and physical characteristics of the soil. It can do so by protecting against desertification and erosion, as well as suppressing plant diseases. The many characteristics of compost help it filter out chemicals and waste.
