   A significant number of the terms included in this glossary are words that can be found in a common dictionary, but that have specific unique meanings in the context of soil survey and soil classification. Examples include artifacts, buried soil, artificial drainage, component, correlation, horizon, and normal year.

   Letters (a, b) indicate multiple buried soil horizons within a vertical profile. Numbers (1, 2) indicate buried soils from different profiles or sites reported in the same study. Burial times and soil ages are based on dates of the burial deposits or buried horizons as reported by the authors.

   The arrangement of these horizons in a soil is known as a soil profile. Soil scientists, who are also called pedologists, observe and describe soil profiles and soil horizons to classify and interpret the soil for various uses.

   A buried A horizon is a clear indication that soil and landscape processes have changed some time in the past. Compared to other mineral horizons (E, B, or C) in the soil profile, they are rich in organic matter, giving them a darker color.

   What is a buried soil profile?

   • A buried soil profile, or paleosol (above geologist ‘s head), represents soil development during the last interglacial period. A modern soil profile (Alfisol) occurs near the land surface. Source: D. Grimley. Soil is important to our society primarily because it provides the foundation of agriculture and forestry.

   How many horizons are in a soil profile?

   • There are five : O, A, E, B, and C. (R is used to denote bedrock.) There is no set order for these horizons within a soil. Some soil profiles have an A-C combination, some have an O-E-B, an O-A-B, or just an O. Some profiles may have all the horizons, O-A-E-B-C-R.

   What is a soil profile?

   • Descriptions of soils are commonly referred to as “pedon descriptions”; in practice, however, it is more accurate to call them “profile descriptions” because most are a description of a two-dimensional face of an exposed soil, as in a pit or road cut, rather than the result of the dissection of a three-dimensional volume of soil. See soil profile.

   What does horizon mean in a soil profile?

   • Soil profile descriptions use horizon suffix symbols (such as z, n, y, or k) to indicate salt accumulation (e.g., Bz, Btn, Bky). Solum.—The part of a soil profile that formed by pedogenic processes; commonly made up of horizons designated A, E, and B, but not including the underlying C or R horizon.

   What is a layer in a soil profile?

   • Layer.—A zone within a soil profile for which some or all soil properties are thought to be inherited from the parent material and not the result of pedogenesis. In this case, “layer” is used rather than “horizon.” The term “layer” may also be used when no judgement is made as to the genetic origin of the zone. See horizon.

   What does buried soil mean?

   • See buried soil. Buried soil.—A soil profile having one or more genetic horizons that is covered with a surface mantle of new soil material 50 cm or more thick. In essence, two soils are present—a new soil in the mantle and an older soil below that formed before the mantle was deposited.
