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 ...
The relationship between the soil-water content (by mass or volume) and the soil-water matric potential. Also called the water retention curve or isotherm, and the water release curve.
Industry:Earth science
The inverse of flocculation. When soil solutions are at low ionic strength and dominated by alkali metal cations, especially at higher pH values, soil colloidal particles can be dispersed throughout the solution.
Industry:Earth science
The total length, including solid particles and pores, of a straight-line path through the soil; the length counterpart of bulk volume or bulk area.
Industry:Earth science
The immobilization of phosphorus by strong adsorption or precipitation.
Industry:Earth science
The process by which available plant nutrients are rendered less available or unavailable in the soil. Not to be confused with dinitrogen fixation.
Industry:Earth science
The growth and reproduction of an organism is dependent on the nutrient substance that is available in minimum quantity.
Industry:Earth science
The downward movement of water through soil. Especially, the downward flow of water in saturated or nearly saturated soil at hydraulic gradients of the order of 1. 0 or less.
Industry:Earth science
The branches of engineering and soil science that deal with the effect of forces on the soil and the application of engineering principles to problems involving the soil.
Industry:Earth science
The activity of potential determining ion in a solution in equilibrium with a variable charge surface whose net electrical charge is zero. For soils it refers to the pH of the isoelectric point of pH dependent charge materials. It applies only to single components, not mixtures.
