Chemical elements that function in plant metabolism whether or not their action is specific.
Industry:Earth science
Land smootihng- a process whereby the surface of the soil is shaped to improve water runoff.
Industry:Earth science
Fungus that attacks lignin, along with cellulose and hemicellulose, leading to complete decomposition of wood; some members are important in bioremedtiation of xenobiotics that resemble lignin, i.e., polycyclic aromatic hydrocarbons.
Industry:Earth science
An organism that can carry out both options of a mutually exclusive process (e.g., aerobic and anaerobic metabolism). May also be used in reference to other processes, such as photosynthesis (e.g., a facultative photosynthetic organism is one that can use either light or the oxidation of organic or inorganic compounds as a source of energy).
Industry:Earth science
Elements or compounds essential as raw materials for organism growth and development.
Industry:Earth science
An octahedral sheet or a mineral containing such a sheet that has two-thirds of the octahedral sites filled by trivalent ions such as aluminum or ferric iron.
Industry:Earth science
A type of forest humus characterized by an accumulation or organic matter on the soil surface in matted Oe(F) horizons, reflecting the dominant mycogenous decomposers. The boundary between the organic horizon and the underlying mineral soil is abrupt. Sometimes differentiated into the following groups: Hemimor, Humimor, Resimor, Lignomor, Hydromor, Fibrimor, and Mesimor.
Industry:Earth science
Fluvial erosion of a land surface or landform by the cutting of gullies, arroyos, canyons, or valleys leaving ridges, hills, mountains or flat-topped remnants separated by drainageways.
