Industry:Earth science
Inceptisols that are saturated with water for periods long enough to limit their use for most crops other than pasture or woodland unless they are artificially drained. Aquepts have either a histic or umbric epipedon and gray colors within 50 cm of the surface, or an ochric epipedon underlain by a cambic horizon with gray colors, or have sodium saturation of 15% or more.
Industry:Earth science
Amount of heat required to raise the temperature of a given quantity of soil by 1 °C.
Industry:Earth science
A variety of cone penetrometer which utilizes dropping weights to provide known increments of force applied to the cone, resulting in measured increments of soil penetration.
Industry:Earth science
Mollisols that have an albic horizon immediately below the mollic epipedon. These soils have an argillic or natric horizon and mottles, iron-manganese concretions, or both, within the albic, argillic or natric horizon.
Industry:Earth science
Refers to the full range of activities that collects information from a distance, e.g., the utilization at a distance (as from aircraft, spacecraft, or ship) of any device for measuring electromagnetic radiation, force fields, or acoustic energy. The technique employs such devices as the camera, lasers, and radio frequency receivers, radar systems, sonar, seismographs, gravimeters, magnetometers, and scintillation counters.
Industry:Earth science
Clusters of microaggregates with associated water within which microorganisms function; may be composed of several microsites (i.e., aerobic and anaerobic).
Industry:Earth science
A term used, especially in southeast Australia, for silt and sand-sized aggregates of eolian clay occurring in sheets.
Industry:Earth science
