A small volume of soil where biological or chemical processes differ from those of the soil as a whole, such as an anaerobic microsite of a soil aggregate or the surface of decaying organic residues.
Industry:Earth science
A general term for a mass movement landform and a process characterized by a flowing mass of predominantly fine-grained earth material (particles less than 2 mm comprising more than 50 percent of the solid material) possessing a high degree of fluidity during movement. If more than half of the solid fraction consists of material larger than sand size, debris flow is preferred.

Industry:Earth science
The percentage of water contained in a soil that has been saturated, subjected to, and is in equilibrium with, an applied pressure of one-third bar. Approximately the same as one-third-atmosphere percentage.
Industry:Earth science
A body of alluvium, nearly flat and fan-shaped, deposited at or near the mouth of a river or stream where it enters a body of relatively quiet water, usually a sea or lake.
Industry:Earth science
A group of related soils that differ, one from the other, primarily as a result of differences in time as a soil-forming factor.
Industry:Earth science
A product of intermediary metabolism released from a cell.
Industry:Earth science
A mineral soil horizon that satisfied the requirements of an argillic horizon, but that also has prismatic, columnar, or blocky structure and a subhorizon having >15% saturation with exchangeable Na+.
Industry:Earth science
A soil with well-developed soil horizons produced by the natural processes of soil formation and essentially in equilibrium with its present environment.
