Humankind owes its existence to the thin layer of topsoil that covers much of the earth. Soil takes hundreds of years to form and from it we derive food, fiber, and shelter. Therefore, how we care for and use soil will always be important. This bulletin describes the importance of soil quality and how it may be defined, evaluated, and managed in vegetable and small fruit production. A glossary of terms used to describe and evaluate soil quality is included at the end of the publication. Selected soil quality-related publications and websites are also provided for additional reference.
