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 ...
The acidity of a soil that can be neutralized by lime or a solution buffered in the range of 7 to 8.
Industry:Earth science
The collective designation of seven so-called limits of consistency of fine-grained soils, suggested by Albert Atterberg, 1911-1912, but with current usage usually retaining only the liquid limit, the plastic limit, and the plasticity number (or index).
Industry:Earth science
The cone-shaped tip used at the insertion end of soil penetrometer probes, following design criteria prescribed by the ASAE standard. Briefly, a 30 degree stainless steel cone having a basal diameter of either 20. 27 mm or 12. 83 mm.
Industry:Earth science
The hillslope position that forms the uppermost inclined surface near the top of a slope. If present, it comprises the transition zone from backslope to summit. This position is dominantly convex in profile and erosional in origin.
Industry:Earth science
The law describing the movement of electricity as caused by a gradient in electrical potential.
Industry:Earth science
The proportionality factor in Darcy's Law, as applied to viscous flow of water in soil, that represents the ability of soil to conduct water and is equivalent to the flux of water per unit gradient of hydraulic potential.
Industry:Earth science
The process of comparing a model's predictions to other "verified" codes to determine that model's code is funtioning properly.
Industry:Earth science
The relationship between the percentage of water under field conditions and the percentages of inorganic clay and of humus.
Industry:Earth science
The process of treating a fertilizer source with an acid. The most common process is treatment of phosphate rock with an acid (or mixture of acids) such as sulfuric, nitric, or phosphoric acid.
