A microcrystalline, calcium fluorophosphate of sedimentary or igneous origin of varying P content. It is usually concentrated and solubilized to be used directly or concentrated in manufacture of commercial phosphate fertilizers.
Industry:Earth science
A gently sloping area adjacent to a lake or ocean that lies between the low and high water marks, which is devoid of vegetation, and is composed of unconsolidated material, typically sand or gravel, deposited by waves or tides.
Industry:Earth science
The percentage of water contained in a soil that has been saturated, subjected to, and is in equilibrium with, an applied pressure of 15 bars. Approximately the same as the fifteen-atmosphere percentage.
Industry:Earth science
The process of attachment of non-ionic substances such as polar water molecules, acetic acid molecules, or nucleic acids to clays or to other solid-phase surfaces. The attachment of large molecules to clay particles by ionic processes is not physiosorption.
Industry:Earth science
Plants that require or tolerate considerable amounts of calcium, or are associated with soils rich in calcium.
Industry:Earth science
A close interaction between a free-living diazotrophic organism and a higher plant that results in enhanced dinitrogen fixation rates.
Industry:Earth science
A dimensionless parameter, calculated from the product of the pore water velocity and the linear distance traveled divided by the dispersion coefficient, used to describe the shape of a solute breakthrough curve.
Industry:Earth science
A ridge-like accumulation that is being or was produced at the outer margin of an actively flowing glacier at any given time; a moraine that has been deposited at the outer or lower end of a valley glacier.
