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 ...
One or more polypedons or parts of polypedons within a delineation of a map unit, not identified by the map unit name; i.e., is not one of the named component soils or named miscellaneous area components. Such soils or areas are either too small to be delineated separately without creating excessive map or legend detail, or occur too erratically to be considered a component, or are not identified by practical mapping methods.
Industry:Earth science
Histosols that have a high content of plant materials so decomposed that original plant structures cannot be determined and a bulk density of about 0. 2 Mg m-3 or more. Saprists are saturated with water for periods long enough to limit their use for most crops unless they are artificially drained.
Industry:Earth science
Prefix designating an association or relationship with a fungus (e.g., mycotoxins are toxins produced by a fungus).
Industry:Earth science
Salt lifted by wind from the spray of sea water or salt lakes, blown inland, and returned to the originating water body via drainage.
Industry:Earth science
Complex microrelief created by numerous cradle knolls and their attendant pits. Usually associated with forested sites or cleared sites that have not been plowed.
Industry:Earth science
Movement of soil nutrients from one life form to another as a result of the different feeding habits and dietary requirements of the organisms in the soil ecosystem.
Industry:Earth science
Soft and unconsolidated calcium carbonate, usually mixed with varying amounts of clay or other impurities.
Industry:Earth science
A thin organic soil horizon that is saturated with water at some period of the year unless artificially drained and that is at or near the surface of a mineral soil. The histic epipedon has a maximum thickness depending on the kind of materials in the horizon and the lower limit of organic carbon is the upper limit for the mollic epipedon.
Industry:Earth science
Oxisols that are moist all or most of the time, and that have a low to moderate content of organic carbon within the upper 1 m or a mean annual soil temperature of 22°C or more.
