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 ...
Mycorrhizal type that forms highly branched arbuscles within root cortical cells of host or compatible plants.
Industry:Earth science
Soil properties related to volcanic origin of materials. The properties include organic carbon content, bulk density, phosphate retention, and iron and aluminum extractable with ammonium oxalate.
Industry:Earth science
Proportionality constant which indicates the ability of a material to allow gases and ions to flow under a partial pressure or concentration gradient.
Industry:Earth science
Rock derived from preexisting rocks that have been altered physically, chemically, and/or mineralogically as a result of natural geological processes, principally heat and pressure, originating within the earth. The preexisting rocks may have been igneous, sedimentary, or another form of metamorphic rock.
Industry:Earth science
Erosion process typically involved in gully formation and bank failure in which subsurface flow exiting the soil transports soil particles entrained in the seepage water.
Industry:Earth science
A technique for demonstrating or estimating denitrification by measuring nitrous oxide (N2O) released from acetylene-treated soil. Acetylene inhibits nitrous oxide reduction to dinitrogen (N2) by denitrifying bacteria.
Industry:Earth science
Free water surface where soil water is at atmospheric pressure.
Industry:Earth science
Accelerated erosion which results in subterranean voids and tunnels.
Industry:Earth science
An estimation of plant mineral nutrient status from the chemical composition of selected plant parts, and the color and growth characteristics of the plant foliage.
