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 ...
A suborder of intrazonal soils, consisting of seven great soil groups, all formed under conditions of poor drainage in marshes, swamps, seepage areas, or flats.
Industry:Earth science
An ephemerally flooded, vegetatively barren area on a basin floor that is veneered with fine-textured sediment and acts as a temporary or as the final sink for drainage water.
Industry:Earth science
An influence which produces or tends to produce motion or change in motion.
Industry:Earth science
Generally used for remote sensing in two or more spectral bands, such as visible and IR.
Industry:Earth science
Adsorption of ions that occurs with the retention of waters of hydration between the surface and the adsorbed ion where the force that retains the ion is only electrostatic attraction. Ions that are retained by outer sphere adsorption are readily exchangeable.
Industry:Earth science
Predictions of soil behavior in response to specific uses or management based on inferences from soil characteristics and qualities (e.g., trafficability, erodibility, productivity, etc. ). They are either qualitative or quantitative estimates or ratings of soil productivities, potentials, or limitations.
Industry:Earth science
Organic chemicals with two or more functional groups that can bind with metals to form a ring structure. Soil organic matter can form chelate structures with some metals, especially transition metals, but, much metal ion binding in soil organic matter probably does not involve chelation. Artificial chelating compounds are sometimes added to soil to increases the soluble fraction of some metals.
Industry:Earth science
Relatively large voids, usually irregular and not normally interconnected with other voids of comparable size; at the magnifications at which they are recognized they appear as discrete entities.
Industry:Earth science
An isolation volume of soil used to conduct three-dimentional flow and transport studies.
