A soil profile is a vertical cross section of soil that extends from the surface to the deepest extent of plant root activity or to the regolith and bedrock. A polypedon is a group of soil pedons that are similar in their horizons and other soil characteristics. A pedon is the smallest unit of soil that can be studied as a separate entity. A soil horizon is a layer in the soil profile that is characterized by distinct physical, chemical, and biological properties.
