Unconsolidated and partly weathered mineral materials accumulated by disintegration of consolidated rock in place.
Industry:Earth science
The upper surface of ground water or that level in the ground where the water is at atmospheric pressure.
Industry:Earth science
The sum of exchangeable bases plus total soil acidity at a specific pH, values, usually 7. 0 or 8. 0. When acidity is expressed as salt extractable acidity, the cation exchange capacity is called the effective cation exchange capacity (ECEC) because this is considered to be the CEC of the exchanger at the native pH value. It is usually expressed in centimoles of charge per kilogram of exchanger (cmolckg-1) or millimoles of charge per kilogram of exchanger.
Industry:Earth science
To treat, usually seeds, with microorganisms to create a favorable response. Most often refers to the treatment of legume seeds with Rhizobium or Bradyrhizobium to stimulate dinitrogen fixation but also refers to the introduction of microbial cultures into sterile growth medium.
Industry:Earth science
The solution extracted from a soil at its saturation water content.
Industry:Earth science
The top layer of ground subject to annual thawing and freezing in areas underlain by permafrost.
Industry:Earth science
Stress surfaces that are polished and striated produced by one mass sliding past another. Slickensides are common below 50 cm in swelling clays subject to large changes in water content.
Industry:Earth science
The arrangement of plasma, skeleton grains, and associated simple packing voids.
Industry:Earth science
The time rate of transport of a quantity (e.g., mass or volume of fluid, electromagnetic energy, number of particles, or energy) across a given area.
