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 ...
Too much or too rapid loss of water from soils, either by percolation or by surface flow. The occurrence of internal free water is very rare or very deep.
Industry:Earth science
Subsoil diagnostic horizon having a clay increase relative to overlying horizons and has low activity clays i.e., <16 cmolc kg-1 clay.
Industry:Earth science
Trioctahedral 1:1 type layer silicate: (Mg, Fe)<SUB. 3< sub>SI2O5(OH)4
Industry:Earth science
Ultisols that have low or moderate amounts of organic carbon, are brownish or reddish throughout, and have a xeric soil moisture regime.
Industry:Earth science
The formation of gas or water vapor-filled cavities in a liquid volume when the pressure is reduced (tension is increased) to a critical level. In water systems cavitation typically occurs at about 0. 08 MPa of water tension. In confined systems, cavitation can create discontinuity of water columns preventing the non-elastic transmission of pressure along the column across the cavitation.
Industry:Earth science
The sequence of transformations whereby carbon dioxide is converted to organic forms by photosynthesis or chemosynthesis, recycled through the biosphere (with partial incorporation into sediments), and ultimately returned to its original state through respiration or combustion.
Industry:Earth science
The state of being physically or chemically balanced, when forces (energy, concentration,. . ) equalize such that mass or energy transfer ceases.
Industry:Earth science
The soil-water content expressed as the volume of water per unit bulk volume of soil.
