Areas having a puddled or crusted, very smooth, nearly impervious surface. The underlying material is dense and massive. A also miscellaneous area.
Industry:Earth science
Frozen water in the interstitial pores of a porous medium.
Industry:Earth science
Areas covered with overburden and other waste materials from ore and coal mines, quarries and smelters, and usually with little or no vegetative cover.
Industry:Earth science
A three-dimensional unit within the s-matrix of the soil material. Its morphology is incompatible with its present occurrence being within a single void in the present soil material. It is recognized as a unit either because of a greater concentration of some constituent and/or a difference in fabric compared with the enclosing soil material, or because it has a distinct boundary with the enclosing soil material.
Industry:Earth science
Biochemical oxidation of ammonium and/or organic nitrogen to nitrate and nitrite by heterotrophic microorganisms.
Industry:Earth science
Aridisols that have a cryic soil temperature regime.
Industry:Earth science
Andisols that have 1500-kPa water retention of <15 % on air dry <30 % on undried samples throughout 60% of the thickness either; a) within 60 cm of the soil surface or top of an organic layer with andic properties, whichever is shallower if there is no lithic, paralithic contact, duripan, or petrocalcic horizon within that depth, or b) between the mineral soil surface or top of an organic layer with andic properties, whichever is shallower and a lithic, paralithic contact, duripan, or petrocalcic horizon. (A suborder in the U. S. system of soil taxonomy).
Industry:Earth science
Soil containing sufficient free CaCO3 and other carbonates to effervesce visibly or audibly when treated with cold 0. 1M HCl. These soils usually contain from 10 to almost 1000g kg-1 CaCO3 equivalent.
Industry:Earth science
CaSO4•2H2O. The common name for calcium sulfate, used to supply calcium to ameliorate soils with a high exchangeable sodium fraction.
Industry:Earth science
A vertically elongated path of preferential water flow in soil.
