Any one of the ranks of the system of soil classification in which soils are grouped on the basis of their characteristics.
Industry:Earth science
Fertilizers made by processes involving treatment of phosphate rock with nitric acid or a mixture of nitric, sulfuric, or phosphoric acids, usually followed by ammoniation. Water solubility of the phosphorus content may vary over a wide range.
Industry:Earth science
Atoms, groups of atoms, or compounds, which are electrically charged as a result of the loss of electrons (cations) or the gain of electrons (anions).
Industry:Earth science
Having a hard, brittle consistency because the particles are held together by cementing substances such as humus, CaCO3, or the oxides of silicon, iron, and aluminum. The hardness and brittleness persist even when wet.
Industry:Earth science
A test in which a cylindrical specimen of soil umbric epipedon encased in an impervious membrane is subjected to a confining pressure and then loaded.
Industry:Earth science
Bond resulting from the attraction of positively charge nuclei and valence electrons that can freely migrate amongst all the nuclei in a substance.
Industry:Earth science
Oxisols that have an ustic moisture regime and either hyperthermic or isohyperthermic soil temperature regimes or have <20 kg organic carbon in the surface cubic meter.
Industry:Earth science
Inherent attributes of soils which are inferred from soil characteristics or indirect observations (e.g., compactibility, erodibility, and fertility).
