GLOSSARYThis is included to define terms commonly used in the report ;it is not a comprehensive soil glossary .aeolian deposit - material deposited by wind, includes both loess anddune sandaggregate - a group of soil particles cohering so asto behave mechanicallyas a unitalluvial deposit - material deposited by moving wateraspect - orientation of the land surface with respect to compass directionAtterberg limits - see plastic limit, liquid limitavailable plant nutrients - that portion of any element or compound inthe soil that can be readily absorbed and assimilated by growingplantscarbon-nitrogen ratio - ratio of organic carbon to total nitrogencation - an ion carrying a positive charge of electricity .The commonsoil cations are calcium, magnesium, sodium, potassium andhydrogen .cation-exchange capacity (C .E .C .)- a measure of the total amount of. exchangeable cations that can be held by the soil . It isexpressed in terms of milliequivalents per 100 grams of soil .coarse fragments -rock or mineral particles greater than 2 mm indiametercolluvium - a heterogeneous mixture of material that has been depositedmainly by gravitational action
113creep - slow mass movement ofsoil and soil material down rather steepslopes primarily under the influence ofgravity, but aided bysaturation with water and alternate freezing and thawing .cryoturbation - frost action, including frost heavingedaphic - (i) of or pertaining to the soil, (ii) resulting from, orinfluenced by,factors inherent in the soil or other substraterather than by climatic factorseluviation - the removal of soil material in suspension or in solutionfrom a layer or layers of the soilerosion - the wearing away of the land surface by running water, wind,or other erosive agents . It includes both normal and acceleratedsoil erosion .The latter is brought about by changes in thenatural cover or ground conditions and includes those due tohuman activity .gley - gleying isa reduction process that takes place in soils that aresaturated with water for long periods of time .The horizon ofmost intense reduction ischaracterized by a gray, commonly mottledappearance, which on drying shows numerous rusty brown iron stainsor streaks . Those horizons in which gleying is intense are designatedwith the subscript g .groundwater - that portion of the total precipitation which at any particulartime is either passing through or standing in the soil and the underlyingstrata and is free to move under the influence of gravity .horizon - a layer in the soil profile approximately parallel to the landsurface with more or less well-defined characteristics that havebeen produced through the operation of soil forming processes .Soilhorizons may be organic or mineral .
