Types of Soil
Potentially acid sulfate soils (also called cat-clays) are often not cultivated or, if they are, planted with rice, so that the soil can be kept wet preventing oxidation.
An acrisol is a type of soil as classified by the Food and Agriculture Organization. It is clay-rich, and is associated with humid, tropical climates, such as those found in Brazil, and often supports forested areas.
Expert opinions on Akadama for Bonsai soil. The experts answer a few questions that Bonsai Empire asked them about Akadama, and its use as Bonsai soil.
Alfisols are a soil order in USDA soil taxonomy. Alfisols form in semiarid to humid areas, typically under a hardwood forest cover. They have a clay-enriched subsoil and relatively high native fertility. "Alf" refers to aluminium (Al) and iron (Fe).
Andisol, one of the 12 soil orders in the U.S. Soil Taxonomy. Andisols are defined by the single property of having volcanic-ash parent material. Although these soils exist in all climatic regions, they account for less than 0.75 percent of all the nonpolar continental land area on Earth.
Anthrosol, one of the 30 soil groups in the classification system of the Food and Agriculture Organization (FAO). Anthrosols are defined as any soils that have been modified profoundly by human activities, including burial, partial removal, cutting and filling, waste disposal, manuring, and irrigated agriculture.

Antigo soils are among the most extensive soils in Wisconsin. They occur on about 300,000 acres (1,200 km²) in the northern part of the State. Antigo soils are well-drained and formed under northern hardwood forests in loess and loamy sediments over stratified sandy outwash.
Aridisols (or desert soils) are a soil order in USA soil taxonomy. Aridisols (from the Latin aridus, for “dry”, and solum) form in an arid or semi-arid climate. Aridisols dominate the deserts and xeric shrublands, which occupy about one third of the Earth's land surface.
Construction on bay mud sites is difficult because of the soil's low strength and high compressibility. Very lightweight buildings can be constructed on bay mud sites if there is a thick enough layer of non-bay-mud soil above the bay mud, but buildings which impose significant loads must be supported on deep foundations bearing on stiffer ...

Brickearth is a term originally used to describe superficial windblown deposits found in southern England. The term has been employed in English-speaking regions to describe similar deposits. The term has been employed in English-speaking regions to describe similar deposits.
Brown earth is a type of soil.Brown earths are mostly located between 35° and 55° north of the Equator.The largest expanses cover western and central Europe, large areas of western and trans-Uralian Russia, the east coast of America and eastern Asia. Here, areas of brown earth soil types are found particularly in Japan, Korea, China, eastern Australia and New Zealand.
Brown podzolic soils are a subdivision of the Podzolic soils in the British soil classification. Although classed with podzols because they have an iron-rich, or spodic horizon, they are, in fact intermediate between podzols and Brown earths.

Calcisol, one of the 30 soil groups in the classification system of the Food and Agriculture Organization (FAO). Calcisols are characterized by a layer of translocated (migrated) calcium carbonate—whether soft and powdery or hard and cemented—at some depth in the soil profile.
Cambisol, one of the 30 soil groups in the classification system of the Food and Agriculture Organization (FAO). Cambisols are characterized by the absence of a layer of accumulated clay, humus, soluble salts, or iron and aluminum oxides.
The Casa Grande is the official state soil of Arizona.
Cecil (soil) permanent dead link]Originally mapped in Cecil County, Maryland in 1899, more than 10 million acres (40,000 km²) of the Cecil soil series (Fine, kaolinitic, thermic Typic Kanhapludults) are now mapped in the Piedmont region of the southeastern United States.
Charlottetown soil series is the name given to a deep fine sandy loam soil which has developed under forest vegetation on glacial till. This series occurs only on Prince Edward Island, where it is widespread and so important for agriculture that it has been designated as the Provincial Soil.
Chernozem (Russian: Чернозём, tr. chernozyom, IPA: [tɕɪrnɐˈzʲom]; "black soil") is a black-colored soil containing a high percentage of humus (4% to 16%), and high percentages of phosphoric acids, phosphorus and ammonia.
Clay soil can feel like a curse to gardeners and can be difficult to plant, shovel or till. When it is compacted, it is nearly impossible to break up using only physical strength. Different machinery may be able to provide a better option for tilling and shoveling the clay soil.
In geology, a claypan is a dense, compact, slowly permeable layer in the subsoil having a much higher clay content than the overlying material, from which it is separated by a sharply defined boundary. Claypans are usually hard when dry, and plastic and sticky when wet. They limit or slow the downward movement of water through the soil.
New Jersey State Soil - Downer New Jersey State Soil - Downer Soil is the unconsolidated mineral and organic material on the immediate surface of the earth that serves as a natural medium for the growth of land plants.
"Durisol" is also a trade name for a type of cement-bonded wood fiber. Distribution of Durisols In the FAO World Reference Base for Soil Resources, a durisol is a very shallow to moderately deep, free-draining soil of arid and semi-arid environments, that contains cemented secondary silica (SiO 2) in the upper metre of soil.

In USDA soil taxonomy, entisols are defined as soils that do not show any profile development other than an A horizon. An entisol has no diagnostic horizons, and most are basically unaltered from their parent material, which can be unconsolidated sediment or rock.
What is an "Expansive Soil"? Expansive soils contain minerals such as smectite clays that are capable of absorbing water. When they absorb water, they increase in volume. The more water they absorb, the more their volume increases. Expansions of ten percent or more are not uncommon.
Neither fill dirt nor topsoil is composed according to standards, but any new homeowner who hasn't demanded topsoil can tell you they differ. The first late-summer hot stretch will give a good indication as to what lies beneath your lush, green lawn, and no amount of fertilizer can remedy an insufficient layer of topsoil.
A flark is a depression or hollow within a bog. Flarks typically occur as a series of parallel depressions, separated by intervening ridges known as strings. Early theories suggested that flarks were formed by frost heaving, but flarks have since been found in areas where frost heaving does not occur.
FLATWOODS SERIES Soils of the Flatwoods series are moderately deep and moderately well drained. They formed in material weathered from acid shale on uplands of the Great Valley. Slopes range from 2 to 15 percent. Mean annual precipitation is about 39 inches, and mean annual temperature is about 56 degrees F.
Fluvisol, one of the 30 soil groups in the classification system of the Food and Agriculture Organization (FAO). Fluvisols are found typically on level topography that is flooded periodically by surface waters or rising groundwater, as in river floodplains and deltas and in coastal lowlands.
Fuller's earth is any clay material that has the capability to decolorize oil or other liquids without chemical treatment. Fuller's earth typically consists of palygorskite (attapulgite) or bentonite.
Gelisols are an order in USDA soil taxonomy. They are soils of very cold climates which are defined as containing permafrost within two meters of the soil surface. The word "gelisol" comes from the Latin gelare meaning "to freeze", a reference to the process of cryoturbation that occurs from the alternating thawing and freezing characteristic of gelisols.
Gleysol, one of the 30 soil groups in the classification system of the Food and Agriculture Organization (FAO). Gleysols are formed under waterlogged conditions produced by rising groundwater. In the tropics and subtropics they are cultivated for rice or, after drainage, for field crops and trees.
Gypsisol, one of the 30 soil groups in the classification system of the Food and Agriculture Organization (FAO). Gypsisols are characterized by a subsurface layer of gypsum (a hydrated calcium sulfate) accumulated by the precipitation of calcium and sulfate from downward percolating waters in the soil profile.
Haplocambids (Great Group: Haplocambids-sub Order Cambids-Order: Aridisols) is a soil Taxonomy great group. Soil with 0-5 slopes over 5 °C temperature and loam soil structure is Haplocambids. Almost cold condition and high altitude soil classified into this group.
In both the FAO soil classification and the USDA soil taxonomy, a histosol is a soil consisting primarily of organic materials. They are defined as having 40 centimetres (16 in) or more of organic soil material in the upper 80 centimetres (31 in).
houston black series The Houston Black series consists of very deep, moderately well drained, very slowly permeable soils that formed in clayey residuum derived from calcareous mudstone of Cretaceous Age.
The definition of a hydric soil is a soil that formed under conditions of saturation, flooding or ponding long enough during the growing season to develop anaerobic conditions in the upper part.
Hydrophobic soil – soil that is hydrophobic – causes water to collect on the soil surface rather than infiltrate into the ground. Wild fires generally cause soils to be hydrophobic temporarily, which increases water repellency, surface runoff and erosion in post-burn sites.
Inceptisol, one of the 12 soil orders in the U.S. Soil Taxonomy. Inceptisols are soils of relatively new origin and are characterized by having only the weakest appearance of horizons, or layers, produced by soil-forming factors.
Soil profile The Jory series consists of very deep, well-drained soils that formed in colluvium derived from basic igneous rock. These soils are in the foothills surrounding the Willamette Valley of the United States.
MICHIGAN’S STATE SOIL~~~KALKASKA SAND. Why and How? A selection process for picking the State Soil from over 400 other Soil Series was started in the 1970's.
Kastanozem, one of the 30 soil groups in the classification system of the Food and Agriculture Organization (FAO). Kastanozems are humus-rich soils that were originally covered with early-maturing native grassland vegetation, which produces a characteristic brown surface layer.
Latosol is a name given to soils found under tropical rainforests with a relatively high content of iron and aluminium oxides. They are typically classified as oxisols (USDA soil taxonomy)or ferralsols (World Reference Base for Soil Resources).
Leptosol, one of the 30 soil groups in the classification system of the Food and Agriculture Organization (FAO). Leptosols are soils with a very shallow profile depth (indicating little influence of soil-forming processes), and they often contain large amounts of gravel.
Lixisol, one of the 30 soil groups in the classification system of the Food and Agriculture Organization (FAO). Lixisols develop on old landscapes in a tropical climate with a pronounced dry season.
