Company Profile:
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 ratio of the thermal conductivity to the volumetric heat capacity.
Industry:Earth science
The sum of exchangeable anions that a soil can adsorb. Usually expressed as centimoles, or millimoles, of charge per kilogram of soil (or of other adsorbing material such as clay).
Industry:Earth science
Stratified detritus (chiefly sand and gravel) removed or "washed out" from a glacier by melt-water streams and deposited in front of or beyond the end moraine or the margin of an active glacier. The coarser material is deposited nearer to the ice.
Industry:Earth science
The force required to crush a mass of dry soil or, conversely, the resistance of the dry soil mass to crushing. Expressed in units of force per unit area (pressure).
Industry:Earth science
The fate of water from the time of precipitation until the water has been returned to the atmosphere by evaporation and is again ready to be precipitated.
Industry:Earth science
The nutrient concentration in the plant, or specified plant part, above which additional plant growth response slows. Crop yield, quality or performance are less than optimum when the concentration is less.
Industry:Earth science
The time rate of transport of a quantity (e.g., mass or volume of fluid, electromagnetic energy, number of particles, or energy) per unit area perpendicular to the direction of flow.
Industry:Earth science
The science dealing with the distribution and movement of water: * agrohydrology - The science dealing with the distribution and movement of rainfall and/or irrigation water and soil solution to and from the root zone in agricultural land, and with the distribution and movement of irrigation and surface water in conveyance systems on agricultural land. * ground-water hydrology - The science dealing with the movement of the soil solution in the saturated zone of the soil profile. * soil hydrology - The science dealing with the distribution and movement of the soil solution in the soil profile. * surface hydrology - The science dealing with the distribution and conveyance of water on the soil surface. * wetland hydrology - The science dealing with water depth, flow patterns and duration, and frequency of flooding that define and delineate wetlands.
Industry:Earth science
Unconsolidated, pyroclastic material less than 2 mm in all dimensions. Commonly called "volcanic ash". Compare cinders, lapilli, tephra.
Industry:Earth science
The decomposed dried excrement of birds and bats, used for fertilizer.
