Soil science
Critical soil test concentration
Earth science; Soil science
That concentration at which 95% of maximum relative yield is achieved. Usually coincides with the inflexion point of a curvilinear yield response curve.
Colour value
Earth science; Soil science
The degree of lightness or darkness of a colour in relation to a neutral grey scale. On a neutral grey scale, value extends from pure black to pure white; one of the three variables of color.
Analytical methods model
Earth science; Soil science
Use of classical mathematical approaches to solve complex formulas, such as differential equations, describing a soil process.
Transfer
Earth science; Soil science
The movement of mass at a point in the soil from one region to another region, e.g., solute movement from adsorbed to solution phases or solute movement from a macropore flow region to a micropore ...
Moisture equivalent
Earth science; Soil science
The weight percentage of water retained by a previously saturated sample of soil 1 cm in thickness after it has been subjected to a centrifugal force of one thousand times gravity for 30 min.
Double chain
Earth science; Soil science
The silica arrangement characteristic of amphiboles where two long chains of linked silica tetrahedra act as a unit.
Compressibility
Earth science; Soil science
The property of a soil pertaining to its susceptibility to decrease in bulk volume when subjected to a load.
