Soil condition in which movement of solute occurs between flow regions, e.g., macropore - micorpore, by diffusion as a result of a gradient in solute concentration between the regions.
Industry:Earth science
Filament of fungal cells. Many hyphal filaments (hyphae) constitute a mycelium. Bacteria of the order Actinomycetales also produce branched mycelium.
Industry:Earth science

Industry:Earth science
A term usually used to describe the response from two or more nutrients applied together that deviates from additive individual responses when applied separately. This term may also be used to describe metabolic or ion-uptake phenomenon.
Industry:Earth science
Mineral soils that have an argillic horizon with a base saturation of <35% when measured at pH 8. 2. Ultisols have a mean annual soil temperature of 8°C or higher. (An order in the U. S. system of soil taxonomy. )
Industry:Earth science
Framework silicates with Al substituting for Si with accompanying Na and/or Ca.
Industry:Earth science
Also known as the relative (dielectric) permitivity. The magnitude of the displacement of constrained charges in response to an electric field. A property of soil constituents representing their magnitude of non-conductance of electricity.
Industry:Earth science
Large masses of ice that formed, in part, on land by the compaction and recrystallization of snow. They may be moving downslope or outward in all directions because of the stress of their own weight or they may be retreating or be stagnant.
