Quizplus · Accepted Answer

A pedon is the smallest sampling unit in soil science and consists of a three-dimensional soil body that represents the characteristics of a particular soil type. It includes all the layers and horizons within a specific area of soil, typically ranging from one to two meters in depth. Soil profiles, polypedons, and soil horizons are all components and characteristics of a pedon, but they do not represent the complete unit of soil that is necessary for sampling and analysis. Therefore, the correct answer is B) Pedon.
