Soil scientists, who are also called pedologists, observe and describe soil profiles and soil horizons to classify and interpret the soil for various uses. Soil horizons differ in a number of easily seen soil properties such as color, texture, structure, and thickness.

The word “soil” has been defined differently by different scientific disciplines. In agriculture and horticulture, soil generally refers to the medium for plant growth, typically material within the upper meter or two (Figure 1). We will use this definition in this chapter. Soil consists predominantly of mineral matter, but also contains organic ma...
Soil is important to our society primarily because it provides the foundation of agriculture and forestry. Of course, soil is also a critical component for terrestrial ecosystems, and thus important to animals, plants, fungi, and microorganisms. Soil plays a role in nearly all biogeochemical cycles on the Earth’s surface. Global cycling of key elem...
The fundamental factors that affect soil genesis can be categorized into five elements: climate, organisms, relief, parent material, and time. One could say that the relief, climate, and organisms dictate the local soil environment and act together to cause weathering and mixing of the soil parent material over time. As soil is formed it often has ...

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.
Modern versus Buried Soil Profiles. 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.
Soil Texture: Soil texture refers to the physical composition of soil defined in terms of the relative proportions, by weight, of each separate. Definitions of the soil texture classes according to distribution

A buried soil is defined by the National Resources Conservation Service as a soil that is “covered with a surface mantle of new soil material that either is 50 cm or more thick or is 30–50 cm thick and has a thickness that equals at least half the total thickness of the named diagnostic horizons that are preserved in the buried soil ...
