	FAO soil classification - Wikipedia, the free encyclopedia
		The FAO developed a supra-national classification, also called World Soil Classification, which offers useful generalizations about soils pedogenesis in relation to the interactions with the main soil-forming factors.
		The FAO soil map is a very simple classification system with units very broad, but it is the only truly international system, and most soils can be accommodated on the basis of their field descriptions.
		The FAO soil map is intended for mapping soils at a continental scale but not at local scale.

	Soil (Site not responding. Last check: 2007-10-24)
		Soil is the layer of minerals and organic matter, in thickness from from centimeters to a meter or more, on the land surface.
		The organic part of soils is derived chiefly from the remains of vegetables and animals which have lived and died in and upon the soil, which have been spread over it by rivers and rains, or which have been added by the industry of man for the purposes of increased fertility.
		Clayey soils, when sufficiently enriched with manures, are naturally well qualified for carrying crops of wheat, oats, beans, and clover; but are not fitted for barley, turnips, potatoes, etc., or even for being kept under for grass longer than one year.

		Soil is the material on the surface of a lithosphere subject to weathering, and especially the earthy portion of that material.
		Soils are vital to all life on Earth because they support the growth of plant s, which supply food and oxygen and absorb carbon dioxide and nitrogen.
		Soil classification is a contentious subject, from the structure of the classification system itself, to the definitions of classes and types, and finally in the application in the field.

		The rock and mineral content is categorized according to particle size as sand (coarsest), silt or clay (finest); the ratio of these particles to a great degree determines the soil classification and characteristics.
		Generally speaking, though, soil is the uppermost layer of the Earth that can support plant life.
		Minerals (also called parent matericals) in soil are obtained from a variety of sources, but the process which delivers the bulk is weathering of rocks.

		The organic part of soils is derived chiefly from the remainsof vegetables and animals which have lived and died in and upon the soil, which have been spread over it by rivers and rains, orwhich have been added by the industry of man for the purposes of increased fertility.
		All clayey soils require great industry and care, as well as a considerable portion of knowledge in dressing ormanagement to keep them in good condition; yet when their natural toughness is got the better of, they always yield the heaviestand most abundant crops.
		Neither of these soils is friendly to grass, yet there is a necessity of exercising this husbandry with them,because they are incapable of standing the plough more than a year or two in the course of a rotation.

	Soil (Site not responding. Last check: 2007-10-24)
		Soil is the layer of minerals and organic matter reaching 1-2m below the Earth's surface.
		Soils differ in the ratio of these elements, but each is essential for plant growth.
		When the level of ions is low in the soil an equilibrium process forces ions back in to solution, where they can be used by plants.

		However if acid acid is introduced into soil, hydrogen hydrogen ions bind in preference to clays, forcing ions out where they can be washed away during rain.

	Soil: Physical Properties
		The kind of soil and its nutrient status found in a given locality is a function of the material from which it weathered, referred to as 'parent material' of the soil.
		The plastic limit is that moisture content of a soil at which it becomes too dry to be plastic, used together with the liquid limit to determine the plasticity index which when plotted against the liquid limit on the plasticity chart enables the classification of cohesive soils.
		Soil humus is a mixture of dark, colloidal organic compounds relatively resistant to decomposition.

		The classification system is set up in a flexible way which allows the user to stop at any time dependent on the level of detail required.
		Classification is an abstract representation of the situation in the field using well-defined diagnostic criteria, the classifiers.
		The classification is truly hierarchical: the difference between a land cover class and a further subdivision of this class is given through the addition of new classifiers.

	Part 7: Non-FAO Land Classification Methods (Site not responding. Last check: 2007-10-24)
		Soils in class 5 have little or no erosion hazards but have other limitations, impractical to remove, that limit their use largely to intensive pasture or range, woodland, or wildlife food or cover.
		Soils in class 6 have severe limitations that make them generally unsuited to cultivation and limit their use largely to pasture or range, woodland, or wildlife food or cover.
		The soil properties necessary for the evaluation are inferred from the map unit name, which in turn implies certain diagnostic horizons, and the map unit phase, for slope and texture.
