Soil science
Potassium fixation
Earth science; Soil science
The process of converting exchangeable or water-soluble potassium to that occupying the position of K+ in the micas. They are counter-ions entrapped in the ditrigonal voids in the plane of basal ...
Pe
Earth science; Soil science
The negative logarithm of the apparent electron activity which can be calculated by including the apparent activity of electrons in equilibrium calculations of redox half-cell reactions. In practise ...
Soil water characteristic or characteristic curve
Earth science; Soil science
The relationship between the soil-water content (by mass or volume) and the soil-water matric potential. Also called the water retention curve or isotherm, and the water release curve.
Deflocculate
Earth science; Soil science
The inverse of flocculation. When soil solutions are at low ionic strength and dominated by alkali metal cations, especially at higher pH values, soil colloidal particles can be dispersed throughout ...
Footslope
Earth science; Soil science
The hillslope position that forms the inner, gently inclined surface at the base of a slope. In profile, footslopes are commonly concave and are situated between the backslope and a toeslope.
Pore water velocity
Earth science; Soil science
The velocity at which water travels in pores relative to a given axis. It is equal to the flux density divided by the soil water content.
Octahedral coordination
Earth science; Soil science
Term describing a cation surrounded by six equidistant anions.
