Soil type

	Soil Orders
		This system for classifying soils has undergone numerous changes since that time, and the 2nd edition was published in 1999.
		Soil Taxonomy remains one of the most widely used soil classification systems in the world.
		At the highest level, Soil Taxonomy places soils in one of 12 categories known as orders.

	Soil - Biocrawler (Site not responding. Last check: 2007-10-25)
		Soil is the layer of minerals and organic matter, in thickness from centimetres to a metre or more, on the land surface.
		Soil is "the collection of natural bodies in the earth's [sic] surface, in places modified or even made by man of earthy materials, containing living matter and supporting or capable of supporting plants out-of-doors.
		Soil includes the horizons near the surface that differ from the underlying rock material as a result of interactions, through time, of climate, living organisms, parent materials, and relief.

	LECTURE NOTES ON THE MAJOR SOILS OF THE WORLD
		Soils with petroplinthite are especially abundant in the transition zone from rain forest to savannah, notably in dry areas that were once much wetter, e.g.
		Weathering processes affect the clay mineralogy of soils; the mineral assemblage of Alisols appears to be in a state of transition from `bisiallitic' high-activity clays to `fermonosiallitic' material that is rich in iron oxides and kaolinite.
		Soil structure is rather weak in the surface horizon because biological activity is hindered by the strong acidity.

	Land Resources of Russia
		In the first step, the soil groups of the Soil Map of Russia (SMR) were correlated with the soil units of the legend of the FAO Soil Map of the World [SMW (FAO, 1988)] and the Soil Taxonomy [ST (Soil Taxonomy, 1999)].
		Further, all soil polygons of the original SMR were described by attributes according to the FAO Revised Legend and the Soil Taxonomy.
		The database under consideration includes new soil data on a considerable part of the Russian North, Siberia and the Far East, all of which have low population densities and are not easily accessible.

	soilmaps
		Soils occur as a continuum in nature, however, crisp classes are used to distinguish soil map units, which differ in one or more characteristics from each other.
		The Manual is intended primarily for use by a soil scientist engaged in the classification and mapping of soils and in the interpretation of soil surveys.
		The profile of this soil is similar to the one described as representative of the series, but the surface layer is a few inches thinner and the substratum typically is at a depth of 50 to 60 inches.

		The application is the development of techniques for alleviation of this source of soil acidity, including methods for predicting the amount of lime to apply to overcome the main problem and for eliminating the side effects and including deficiencies of calcium and micronutrient deficiency and toxicity problems.
		The Soil Science Department was a member of the 4-University Consortium on Soils of the Tropics awarded a grant for development of faculty knowledge and capabilities for participating in technical assistance, technology transfer and training programs in tropical soils of less developed countries.
		The Soil Science Department has conducted field studies in cooperation with the host country agricultural research organizations in the humid tropical jungle area of the Upper Amazon Basin in Peru near Yurimaguas and Manaus, Brazil, and in the humid rainforests of Sumatra, Indonesia.

	A Compendium of On-Line Soil Survey Information : Classification
		Soil Taxonomy was designed to group soil series in the USA in increasingly-general interpretive groups, whereas World Reference Base and its predecessor FAO Legend were designed to understand and organize world soil geography.
		Soil Taxonomy is still being revised, as new knowledge about soils is recorded, and as field scientist, especially in the USA, try to organise existing information in a "more perfect hierarchy".
		Soils are classified directly by a chosen set of characteristics that are thought to relate directly to a certain use or group of uses.

	AUSTRALIAN SOIL IDENTIFICATION SPREADSHEET (ASIS)
		Originally, this soil example was allocated to the GSG class of red- brown earth but in the fuzzy classification it has partial membership in different groups of which the three main ones are: Red Podzolic Soil (0.42), Red-Brown Earth (0.38) and Non-Calcic Brown Soil (0.08).
		This soil is from Reeves County, Texas (refer to 4.4.6), USA (Soil Taxonomy, 1975) and is formed from calcareous, gypsiferous alluvium on a level plain with the following description.
		The soil was allocated to the class of Gypsiorthid in Soil Taxonomy and to the fuzzy classification as an Extragrade (0.61).

	Soil type - Wikipedia, the free encyclopedia
		In terms of soil texture, Soil type usually refers to the different sizes of mineral particles in a particular sample.
		Soil is made up in part of finely ground rock particles, grouped according to size as sand, silt, and clay.
		However, "soil type" in the broader sense refers to a pedological classification of the natural (or human-influenced) soil.

	Andisols \| \| Dictionary & Translation by Babylon
		In USA soil taxonomy, Andisols are soils formed in volcanic ash and defined in terms of the dominance of glass and poorly crystalline colloidal materials such as allophane, imogolite, and ferrihydrite (andic properties).
		In the FAO soil classification, Andisols are known as Andosols.
		These soils develop from parent materials that are volcanic in origin.

	Archaeology
		The soil within a Patriarch garden was classified as eroded ordinary chernozems (Haplic Chernozems, FAO-UNESCO; Argiudolls, USA Soil Taxonomy).
		All the VES curves revealed three-layer soil profile with apparent ER The top layer was represented by the eroded Chernozem of coarse textures with electrical resistivity (ER) about 125 ohm m for loamy sand and about 50 ohm m for sandy clay loam.
		The percentage of clay in the soil increased toward the corner of the church along with the electrical potential.
