Soil that has formed under the influence of cold soil temperatures.
Industry:Earth science
Soil material, usually sand or gravel, with a narrow range of particle sizes.
Industry:Earth science
A surface horizon of mineral soil that is too light in color, too high in chroma, too low in organic carbon, or too thin to be a plaggen, mollic, umbric, anthropic or histic epipedon, or that is both hard and massive when dry.
Industry:Earth science
Microorganisms that grow under both aerobic and anaerobic conditions, but do not shift from one mode of metabolism to another as conditions change; energy is obtained exclusively via fermentation.
Industry:Earth science
A subsurface mineral horizon that is darker in color than the overlying horizon but that lacks the properties of a spodic horizon. Common in cool, moist soils of high altitude in tropical regions.
Industry:Earth science
An electrochemical sensor, the potential of which (in conjunction with a suitable reference electrode) depends on the logarithm of the activity of a given ion in aqueous solution (e.g. pH, copper, nitrate, and sodium electrodes).
Industry:Earth science
Conceptualization that a representative elemental volume of soil at any point consists of distinguishable pore classes, each with unique flow and transport properties.
Industry:Earth science
Diverse group of rhizosphere bacteria that impart beneficial effects on plant growth as root colonizers.
Industry:Earth science
Sediments deposited by running water of streams and rivers. It may occur on terraces well above present streams, on the present flood plains or deltas, or as a fan at the base of a slope.
