- 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 density of the soil particles, the dry mass of the particles being divided by the solid (not bulk) volume of the particles, in contrast with bulk density. Units are Mg m-3.
Industry:Earth science
Translocation of silicate clay particles within a soil, usually downward translocation is implied, and the mechanism of movement is usually infiltrating water. (added 6/1/2000)
Industry:Earth science
The process by which atoms, molecules, or ions are taken up from the soil solution or soil atmosphere and retained on the surfaces of solids by chemical or physical binding.
Industry:Earth science
The volume fractions of the various size ranges of pores in a soil, expressed as percentages of the soil bulk volume (soil particles plus pores).
Industry:Earth science
The volume of water transported per unit of time and per unit of cross-sectional area normal to the direction of water flow.
Industry:Earth science
The conversion of an element from an organic form to an inorganic state as a result of microbial activity.
Industry:Earth science
That part of a soil profile which is behind the wetting front during infiltration and does not increase in water content during further infiltration.
Industry:Earth science
The heat evolved on immersing a soil, at a known initial water content (usually oven dry) in a large volume of water.
Industry:Earth science
The output of a specified plant or group of plants under a defined set of management practices.
Industry:Earth science
The combination or arrangement of primary soil particles into secondary units or peds. The secondary units are characterized on the basis of size, shape, and grade (degree of distinctness).
