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 ...
(i) To provide channels, such as open ditches or drain tile, so that excess water can be removed by surface or by internal flow. (ii) To lose water (from the soil) by percolation.
Industry:Earth science
A soil that formed under conditions of saturation, flooding, or ponding long enough during the growing season to develop anaerobic conditions in the upper part (Federal Register, 1994).
Industry:Earth science
A cone penetrometer with the additional capacity of measuring the local side-friction component of penetration resistance. The resistance to penetration developed by the friction sleeve equals the vertical force applied to the sleeve divided by its surface area.
Industry:Earth science
A mappable area of the earth's surface that has a common history; the area is of similar age and is formed by a set of processes during an episode of landscape evolution. A geomorphic surface can be erosional, constructional or both. The surface shape can be planar, concave, convex, or any combination of these.
Industry:Earth science
A condition which hinders the movement of water through soils under the influence of gravity.
Industry:Earth science
A general term for loose, relatively permeable material, either contained within or accumulated on the surface of a glacier deposited during the downwasting of nearly static glacial ice.
Industry:Earth science
A preferential flow process in which water flows rapidly through a large discrete pore causing tunnel erosion.
Industry:Earth science
A soil amendment containing calcium carbonate, magnesium carbonate and other materials, used to neutralize soil acidity and furnish calcium and magnesium for plant growth. Classification including calcium carbonate equivalent and limits in lime particle size is usually prescribed by law or regulation.
Industry:Earth science
A basal till characterized by compact, fissile or platy structure and containing coarse fragments oriented with their long axes generally parallel to the direction of ice movement.
