Question

The basic sampling unit in soil surveys, representing all the characteristics and variability used for classification is the pedon. A pedon is a three-dimensional soil body that shows the full range of properties and characteristics of a soil, from the surface (topsoil) down to the parent material. It includes all the soil horizons within the profile and is the smallest unit that can be used to represent a soil type. Soil profiles (A) refer to the vertical layers of a soil, soil horizons (C) are the distinct layers of a soil, and polypedons (D) are groups of closely associated pedons that have similar characteristics. However, none of these are the basic sampling unit used for classification in soil surveys.
