- Company Profile:
An international scientific society that fosters the transfer of knowledge and practices to sustain global soils. Based in Madison, WI, and founded in 1936, SSSA is the professional home for 6,000+ members dedicated to advancing the field of soil science. It provides information about soils in ...
Soils that, following wetting, exhibit transient but only slowly reversible cementation and/or induration throughout significant fractions of the profile restrictive to seed emergence and root penetration.
Industry:Earth science
The study of soil morphology by microscopic (light optical and less frequently by submicroscopic) methods, often using thin-section techniques.
Industry:Earth science
The region bounded by the upper and lower soil water content over which water, oxygen, and mechanical resistance are not limiting to plant growth. Compare with available water.
Industry:Earth science
Those metals which have densities >5. 0 Mg m-3. In soils these include the elements Cd, Co, Cr, Cu, Fe, Hg, Mn, Mo, Ni, Pb, and Zn.
Industry:Earth science
The projecting end of an interfluve, where contour lines connecting the opposing side slopes form convex curves around the projecting end and lines perpendicular to the contours diverge downward. Overland flow of water is divergent.
Industry:Earth science
The pigmented organic material that remains in solution after removal of humic acid by acidification. It is separated from the fulvic acid fraction by adsorption on a hydrophobic resin at low pH values.
Industry:Earth science
The ability of a current of water or wind to transport sediment, in terms of particle size rather than amount, measured as the diameter of the largest particle transported. It depends upon velocity: a small but swift current for example, may have greater competence than a larger but slower moving current.
Industry:Earth science
The hillslope position that forms a gently inclined surface at the base of a slope. Toeslopes in profile are commonly gentle and linear, and are constructional surfaces forming the lower part of a slope continuum that grades to a valley or closed depression.
Industry:Earth science
That portion of the water below the surface of the ground at a pressure equal to or greater than atmospheric.
