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 ...
Aridisols which have a salic horizon that has its upper boundary within 100 cm of the soil surface.
Industry:Earth science
Accelerated erosion which results in subterranean voids and tunnels.
Industry:Earth science
In Soil Survey a map-unit that is a type of miscellaneous area, which is generally devoid of vegetation , is intricately dissected by a fine, drainage network with a high drainage density and has short, steep slopes with narrow interfluves resulting from erosion of soft geologic materials. Most common in arid or semiarid regions.
Industry:Earth science
Applied to peds. Virtually none of the faces of adjoining peds are molds of each other.
Industry:Earth science
An organism for which organic compounds serve as both energy and carbon sources for cell synthesis. Used synonymously with "heterotroph".
Industry:Earth science
Elements required by plants to complete their normal life cycles which includes C, H, O, P, K, N, S, Ca, Fe, Mg, Mn, Cu, B, Zn, Co, Mo, Cl, and Na.
Industry:Earth science
An aluminosilicate with primarily short-range structural order. Occurs as exceedingly small spherical particles especially in soils formed from volcanic ash.
Industry:Earth science
Polymers of general composition (Al(OH)3-x)m+nx which are adsorbed on interlayer cation exchange sites. Although not exchangeable by unbuffered salt solutions, they are responsible for a considerable portion of the titratable acidity (and pH-dependent charge) in soils.
Industry:Earth science
In Soil Survey a map unit that is a type of miscellaneous area, which consists of sand dunes and intervening troughs that shift with the wind.
Industry:Earth science
Any soil of the azonal order without definite genetic horizons and developing from or on deep, unconsolidated, soft mineral deposits such as sands, 1oess, or glacial drift.
