- Company Profile:
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 ...
A solute that exhibits no adsorption capacity but could exhibit physical or biological transformations that result in loss from solution.
Industry:Earth science
(i) To unite firmly; the act or process of becoming compact. (ii) (geology) The changing of loose sediment into hard, firm rock. (iii) (soil engineering) The process by which the soil grains are rearranged to decrease void space and bring them into closer contact with one another, thereby increasing the bulk density. (iv) (solid waste disposal) The reducing of the bulk of solid waste by rolling and tamping.
Industry:Earth science
A great soil group, of the intrazonal order and hydromorphic suborder consisting of soil with dark-brown or black peaty material over grayish and rust mottled mineral soil; formed under conditions of poor drainage under forest, sedge, or grass vegetation in cool to tropical humid climates.
Industry:Earth science
(i) The amount of soil nutrient in chemical forms accessible to plant roots or compounds likely to be convertible to such forms during the growing season. and (ii) The contents of legally designated "available" nutrients in fertilizers determined by specified laboratory procedures which in most states constitute the legal basis for guarantees.
Industry:Earth science
A sedimentary layer, lamina, or sequence of laminae, deposited in a body of still water within 1 year; specifically, a thin pair of graded glaciolacustrine layers seasonally deposited, usually by meltwater streams, in a glacial lake or other body of still water in front of a glacier.
Industry:Earth science
A protein produced by the body in response to the presence of an antigen to which it can specifically combine.
Industry:Earth science
(i) It is no longer used in SSSA publications in reference to plant nutrition. (ii) In environmental applications it is those elements exclusive of the eight abundant rock-forming elements: oxygen, aluminum, silicon, iron, calcium, sodium, potassium, and magnesium.
Industry:Earth science
(i) A taxonomic class at the subgroup level of soil taxonomy having properties typical of the great group of which it is a member and that are characteristic of some class in a higher category (any order, suborder or great group) and indicates a transition to that kind of soil. (ii) A soil that is a member of one such subgroup. (iii)an expanding type 2:1 layer silicate which has islands of "gibbsite-like"cationic material in the interlayer spaces.
Industry:Earth science
(i) That which is laid or spread under an underlying layer, such as the subsoil. (ii) The substance, base, or nutrient on which an organism grows. (iii) Compounds or substances that are acted upon by enzymes or catalysts and changed to other compounds in the chemical reaction.
