A representative soil profile of Pullback sandy loam. Pullback soils are shallow to unweathered, hard bedrock and have thick, dark surface layers. They occur on high mountains in the western and southern parts of the county. (Soil Survey of Graham County, North Carolina; by Brian Wood and Southern Blue Ridge Soil Survey Office, Natural Resources Conservation Service)

 

Landscape: A high mountain grassy bald on Huckleberry Knob in an area of Breakneck-Pullback complex, windswept, 15 to 30 percent slopes, very rocky. Areas such as this are highly desirable for wildlife and were once used as summer pasture.

 

The Pullback series consists of shallow, well drained soils on strongly sloping to very steep summits and side slopes in the high elevations of the Southern Blue Ridge mountains, MLRA 130B. They formed in residuum affected by soil creep in the upper part, and weathered from low-grade metasedimentary rocks, primarily metasandstone. Slope ranges from 8 to 95 percent.

 

TAXONOMIC CLASS: Loamy, isotic, frigid Lithic Humudepts

Note: Although Pullback soils may exhibit some of the characteristics of andic soil properties, they lack the volcanic glass found in soils of similar taxa in the Western United States.

 

Solum thickness and depth to lithic contact is less than 20 inches. The content of rock fragments is less than 35 percent by volume throughout. Reaction is extremely acid to strongly acid.

 

Most of the acreage is in public ownership and is used for watershed protection, recreation, and wildlife habitat. In areas higher than about 5400 feet, red spruce and fraser fir are the dominant trees. At the lower elevations, northern red oak, black oak, American beech, yellow birch, black cherry, sugar maple, eastern hemlock, and yellow buckeye are common trees. Common understory plants are serviceberry, striped maple, American chestnut sprouts, silverbell, pin cherry, rhododendron, flame azalea, and blueberry. Common forbs are hay-scented fern, woodfern, New York fern, Solomons seal, yellow mandarin, and trillium. A small acreage is covered by heath balds. These balds are vegetated with rhododendron, mountain laurel, blueberry, flame azalea, hawthorn, and mountain ash. Vegetation ranges for spruce/fur to northern hard woods, heath and grass balds.

The left portion of this ped shows moist soil colors, and the right portion shows dry soil colors. Moist colors are to be used when hydric soils are identified. The moist colors in this picture would meet the requirements for indicator F6 (Redox Dark Surface), but the dry colors would not meet these requirements.

 

All colors noted in this guide refer to moist Munsell colors (X-Rite, 2009). Dry soils should be moistened until the color no longer changes, and wet soils should be allowed to dry until they no longer glisten (fig. 3). Care should be taken to avoid over moistening dry soil.

Sugarcane is commonly grown on Oxisols in Brazil. Oxisols are an order in USDA soil taxonomy, best known for their occurrence in tropical rain forest, 15-25 degrees north and south of the Equator. They are classified as ferralsols in the World Reference Base for Soil Resources; some oxisols have been previously classified as laterite soils.The main processes of soil formation of oxisols are weathering, humification and pedoturbation due to animals. These processes produce the characteristic soil profile. They are defined as soils containing at all depths no more than 10 percent weatherable minerals, and low cation exchange capacity. Oxisols are always a red or yellowish color, due to the high concentration of iron(III) and aluminium oxides and hydroxides. In addition they also contain quartz and kaolin, plus small amounts of other clay minerals and organic matter.

A soil profile of a well drained Paleustoll in a semiarid area of the southern Great Plains. It has a mollic epipedon about 26 cm thick. Below this epipdon is an argillic horizon that extends to a depth of about 110 cm. Below 110 cm is a calcic horizon. The left side of the scale is in 20-cm increments. (Soil Survey Staff. 2015. Illustrated guide to Soil Taxonomy. U.S. Department of Agriculture, Natural Resources Conservation Service, National Soil Survey Center, Lincoln, Nebraska)

 

Paleustolls are the Ustolls on old stable surfaces, as evidenced by the development of a thick, reddish argillic horizon, a clayey argillic horizon that has an abrupt upper boundary, or a petrocalcic (cemented by calcium carbonate) horizon. These soils commonly have been partly or completely calcified during the Holocene, and calcium carbonate has accumulated in the previously formed argillic horizon. The Paleustolls in the United States are mainly in the central and southern parts of the Great Plains. At the time of settlement, they had mostly grass vegetation. Their history during the Pleistocene has had little study. The petrocalcic horizon, where it occurs, may be complex, suggesting a number of alternating cycles of humidity and aridity and slow accretion of dust and sediment from the arid regions to the west.

When photographing soil profiles, a soil scientist will commonly use a knife to pick the face to show natural soil structure (left side of profile). Or they may use a knife or shovel to smooth the surface (right side of the profile) which helps show change in color or pedogenic features, or horizonation.

 

Marton soils from 0 - 25 cm; Dark greyish brown to very dark greyish brown silt loam, fine polyhedral structure. In the New Zealand Soil Classification system these soils are Argillic-fragic Perch-gley Pallic Soils. For more information about the New Zealand Soil Classification system, visit;

In U.S. Soil Taxonomy, these soils are Aeric Kandiaqualfs. Aeric Kandiaqualfs below the A or Ap horizon, chroma that is too high for the Typic subgroup, but they are otherwise like Typic Kandiaqualfs in their defined properties and in most other properties. Aeric Kandiaqualfs are not known to occur in the United States.

 

Kandiaqualfs are the wet Alfisols that have a frigid, mesic, isomesic, or warmer temperature regime and a kandic horizon. The soils are allowed, but not required, to have a glossic horizon. Characteristically, they have the most warm and humid climates of the Aqualfs and the most water passing through the profile and have a relatively low base saturation for soils of this order. The vegetation is mostly tropical or subtropical hardwood forest. Slopes are nearly level or concave. Kandiaqualfs are mostly in tropical and subtropical areas. They are rare in the United States.

Soil profile: A representative soil profile of very deep, excessively drained, disturbed soils in Korea.

 

Landscape: These Udorthents are in valleys. They formed from cut and fill materials from the surrounding uplands.

 

Udorthents are the Orthents of cool to hot, moist regions. They have a udic moisture regime and a temperature regime warmer than cryic. Generally, they are acid to neutral. Slopes generally are moderate to steep but are gentle in a few areas. Udorthents commonly occur in areas of very recently exposed regolith, in areas of weakly cemented rocks, or in areas of thin regolith over hard rocks.

 

Many of the gently sloping soils are the result of earth-moving activities. The vegetation is commonly a deciduous forest, or the soils are used as pasture. Udorthents are extensive soils on steep slopes in the humid parts of the United States.

 

Orthents are primarily Entisols on recent erosional surfaces. The erosion may be geologic or may have been induced by cultivation, mining, or other factors. Any former soil that was on the landscape has been completely removed or so truncated that the diagnostic horizons for all other orders do not occur. A few Orthents are in areas of recent loamy or fine eolian deposits, Orthents occur in any climate and under any vegetation. They are do not occur in areas that have aquic conditions or a high water table or on shifting or stabilized sand dunes.

A soil profile of a Palexeralf in Victoria, Australia. Clay has been leached from the upper 15 to 25 cm, resulting in a loamy, predominantly gray horizon with a wavy lower boundary. Below this is a thick, reddish, clay-enriched argillic horizon that extends below the base of the photo. (Soil Survey Staff. 2015. Illustrated guide to Soil Taxonomy. U.S. Department of Agriculture, Natural Resources Conservation Service, National Soil Survey Center, Lincoln, Nebraska)

 

Palexeralfs have a petrocalcic (cemented by calcium carbonate) subsoil horizon or an argillic (clay accumulation) or kandic (very low cation-exchange capacity) subsoil horizon that is thick or that has, at its upper boundary, both a clayey texture and a large increase in clay content. Many of these soils have some plinthite (firm, iron oxide-rich concentration that irreversibly hardens after exposure to repeated wet-dry cycles) in their lower horizons, but this feature is rare in the United States. Palexeralfs are in relatively stable landscape positions on gentle slopes, and most began their genesis before the late Pleistocene. During pluvial periods of the Pleistocene, carbonates appear to have been almost completely removed from the argillic or kandic horizon of most of these soils, but some of the soils appear to have been recalcified later. Most Palexeralfs formed in acid or in moderately basic parent materials, but some formed in materials as basic as basalt. The native vegetation on the warmest Palexeralfs in the United States was a mixture of annual grasses, forbs, and woody shrubs. The native vegetation on the coolest Palexeralfs was mostly a coniferous forest. Palexeralfs are moderately extensive in the United States as well as in other parts of the world.

A representative soil profile of the Mountviews soil series. (Soil Survey of Cannon County, Tennessee; by By Jerry L. Prater, Natural Resources Conservation Service)

 

The Mountview series consists of very deep, well drained and moderately well drained, soils that formed in 2 to 3 feet of a silty mantle, presumably loess, and underlying residuum of limestone or old alluvium. Slopes range from 0 to 20 percent. Near the type location, average annual air temperature is about 59 degrees F., and mean annual precipitation is about 54 inches.

 

TAXONOMIC CLASS: Fine-silty, siliceous, semiactive, thermic Oxyaquic Paleudults

 

Solum thickness and depth to rock exceeds 60 inches. The upper solum formed in a silty mantle, presumably loess, and commonly is about 30 inches thick but ranges from about 22 to 36 inches. This overlies a lower solum developed in residuum of limestone or old alluvium. Coarse fragments, commonly fragments of chert, range from 0 to about 5 percent in the upper 30 inches and from about 5 to 35 percent below that depth. Transition horizons have characteristics similar to adjacent horizons. Reaction of each horizon is very strongly acid or strongly acid, except the surface layer is less acid where limed.

 

USE AND VEGETATION: Most areas are used for growing hay, pasture, small grains, cotton, corn, and tobacco. Some areas are in woodland consisting chiefly of oak, hickory, gum, and maple.

The Windsor soil series was established in the Connecticut Valley Area in 1899. On May 3, 1899 with an appropriation of $16,000, Milton Whitney, the Chief of the Division of Agricultural Soils, began four soil survey field operations. One of surveys was located in Connecticut and concentrated on tobacco lands in the Connecticut Valley. The soils of the Connecticut Valley were classified and mapped according to any condition which might influence the character of the vegetation, especially the character of the tobacco, the kind of crops adapted to the land, as well as the quality and quantity of the crops. Windsor was one of the soils classified and mapped this way.

 

Windsor sand it was called, represented the original bottom of the old glacial Lake Hitchcock in its shallowest parts. Initial lab data found the soil to be composed of yellowish-red or brown sand, containing less than 5 percent clay. In favorable seasons, very fine quality thin-leaved silky tobacco was produced on these soils. The Windsor soil was named after the town of Windsor. Windsor is a town in Hartford County, Connecticut and was the first English settlement in the state.

 

Windsor soils throughout its range can be used for agriculture (growing food for humans and animals); engineering (roads, buildings, tunnels); ecology (wetlands); recreation (ball fields, playgrounds, camp areas), and more. Common trees are

white, black, and northern red oak, eastern white pine, pitch pine, gray birch, poplar, red maple, and sugar maple.

In U.S. Soil Taxonomy, these soils are Typic Dystrudepts. Dystrudepts are the acid Udepts of humid and perhumid regions. They developed mostly in late-Pleistocene or Holocene deposits. Some developed on older, steeply sloping surfaces. The parent materials generally are acid, moderately or weakly consolidated sedimentary or metamorphic rocks or acid sediments. A few of the soils formed in saprolite derived from igneous rocks. The vegetation was mostly deciduous trees. Most of the Dystrudepts that formed in alluvium are now cultivated, and many of the other Dystrudepts are used as pasture. The normal horizon sequence in Dystrudepts is an ochric epipedon over a cambic horizon. Some of the steeper Dystrudepts have a shallow densic, lithic, or paralithic contact. Dystrudepts are extensive in the United States. They are mostly in the Eastern and Southern States.

 

Udepts are mainly the more or less freely drained Inceptisols that have a udic or perudic moisture regime. They formed on nearly level to steep surfaces, mostly of late-Pleistocene or Holocene age. Some of the soils, in areas where the soil moisture regime is perudic, formed in older deposits. Most of the soils had or now have a forest vegetation, but some support shrubs or grasses. A few formed from Mollisols by truncation of the mollic epipedon, mostly under cultivation. Most of the soils have an ochric or umbric epipedon and a cambic horizon. Some also have a sulfuric horizon, a fragipan, or a duripan. The Udepts in the United States are most extensive in the Appalachian Mountains, on the Allegheny Plateau, and on the west coast.

An Aquic Cumulic Hapludoll from south-west Poland--lower Silesia region and the Sudetes Mountains formed in loess. (Photo provided by Cezary Kabala, Institute of Soil Science, University of Environmental and Life Sciences, Wroclaw, Poland.).

 

These soils have an overthickened mollic epipedon. They also have lower chroma than Typic Hapludolls, commonly have faint redoximorphic features, and either have shallow ground water at some time during the year or have been artificially drained. They are at the base of slopes or on flood plains, where they receive fresh sediments at a rate slow enough for the material to become incorporated into the mollic epipedon. Some of the soils are calcareous throughout their thickness. Aquic Cumulic Hapludolls are of small extent and are mostly in Iowa. Slopes are gentle and are mostly plane or concave. These soils supported mostly tall grasses and commonly are used as cropland.

 

These soils are classified as a Haplic Chernozems (Aric, Endogleyic, Pachic, Siltic, Bathycalcic) by the World Reference Base (WRB).

Soil profile: Profile of Watahala gravelly silt loam. Yellowish red clay begins at a depth of about 70 Centimeters and extends to below a depth 150 centimeters. (Soil Survey of Bland County, Virginia; by Robert K. Conner, Natural Resources Conservation Service)

 

The Watahala series consists of very deep, well drained soils formed in residuum from chert or cherty limestone over residuum from purer limestone on low hills and ridges in limestone valleys. Permeability is moderately slow to moderately rapid. Slope ranges from 2 to 60 percent. Mean annual precipitation is about 44 inches and mean annual air temperature is about 57 degrees F.

 

TAXONOMIC CLASS: Fine-loamy over clayey, siliceous over mixed, subactive, mesic Typic Paleudults

 

Solum thickness and depth to bedrock are more than 60 inches. Depth to the 2Bt horizon ranges from 20 to 50 inches. Coarse fragments are mostly chert, but may include limestone and sandstone and are mostly gravel or cobble size. Percent coarse fragments range from 10 to 45 in individual horizons above the 2Bt, but the control section averages less than 35 percent. Percent coarse fragments range from 0 to 35 in the 2Bt horizon. Reaction is extremely acid to strongly acid in the upper part of the solum, and very strongly acid to strongly acid in the 2Bt horizon.

 

USE AND VEGETATION: The soils are used for the production of timber and related natural resources. Some areas are used for pasture or have been developed for homesites. Some less sloping areas are used for row crops. The overstory in most areas consists of white oak, red oak, eastern white pine, black locust, chestnut oak, yellow-poplar, red maple, black birch, white ash, and black cherry. The understory contains mountain laurel, huckleberry, azalea, flowering dogwood, sassafras, black locust, black gum, wild grape, red maple, multi-flora rose, Virginia creeper, black birch, black berry and ferns.

 

DISTRIBUTION AND EXTENT: MLRA 128 and 147, Appalachian Ridge and Valley areas of Virginia and northern Tennessee. Series is of moderate extent. Soils now within the range of the Watahala series were correlated as Frederick, gravelly phase in several published soil surveys.

______________________________

 

The Lloyd series consists of very deep, well drained, moderately permeable soils on uplands in the Southern Piedmont. The soils formed in residuum derived from intermediate and mafic, igneous and high-grade metamorphic rocks.

 

TAXONOMIC CLASS: Fine, kaolinitic, thermic Rhodic Kanhapludults

 

Most areas are cleared and used for cultivated crops or pasture. Principal crops are corn, small grain, hay and pasture grasses. Common trees in forested areas are loblolly pine, shortleaf pine, Virginia pine, northern red oak, southern red oak, white oak, post oak, hickory, and red maple. Understory plants include dogwood, winged elm, eastern hophornbeam, eastern redbud, eastern red cedar, and sassafras.

 

These soils are of large extent in the Southern Piedmont in North Carolina, South Carolina and Georgia, and possibly Alabama, and Virginia.

 

These soils were combined with Hiwassee in 1969. Hiwassee series was originally established on high stream terraces. This revision separates the soils formed in residuum as Lloyd on the basis of parent material and depth of Rhodic colors. Terrace Hiwassee soils are dominantly value 3 or less throughout. A proposal to amend the 1996 Keys to Soil Taxonomy involves changing the thickness of the part of the kandic horizon with value of 3 or less to include more soils in the Rhodic subgroup.

In U.S. Soil Taxonomy, these soils are Typic Hapludults. Many of the soils have a thin argillic horizon. The color of the argillic horizon is not both dark and reddish throughout the upper 100 cm. Most of the soils formed in areas of acid rocks or sediments on surfaces that are at least of Pleistocene age. Where the soils are not cultivated, the vegetation consists almost exclusively of forest plants, either hardwood trees or conifers. Hapludults are extensive in the Southeastern United States, in the Middle Atlantic States, and on the coastal plain along the Gulf of Mexico in the Southern States east of the Mississippi River. Slopes generally are gently sloping to steep, but a few of the soils on the lowest part of the coastal plain are nearly level.

The Ras Al Khaimah series is a very deep soil formed in loamy alluvial deposits. (NE019).

 

Taxonomic classification: Typic Haplocambids, coarse-silty, carbonatic, hyperthermic

Diagnostic subsurface horizon described in this profile is: Cambic horizon 10 to 200 cm.

 

The pH (1:1) ranges from 7.0 to 8.3 throughout the profile. The EC (1:1) is generally less than 1 dS/m in all horizons, but ranges to 3.0. EC (1:1) may be higher in some areas that have been irrigated. Most pedons have a deflation gravel lag on the surface covering 2 to 10% of the area. Gravel content is mostly 0 to 5% throughout the profile, but some pedons have layers with up to 65% gravel below depths of 100 cm.

 

The A horizon ranges from about 10 to 20 cm thick. It has hue of 10YR, value of 5 or 6, and chroma of 3 or 4. Texture is fine sandy loam, very fine sandy loam, or loam.

 

The B horizon commonly extends to more than 200 cm in most pedons, but may be underlain by a C horizon at depths of between 100 and 200 cm. Hue is 10YR, value is 4 to 6, and chroma is 3 to 6. Texture is very fine sandy loam, loam, or silt loam.

 

Where encountered, the C horizon has hue of 10YR, value 5 or 6, and chroma 3 or 4. It is gravelly to extremely gravelly loamy sand or sandy loam.

In the Australian soil classification system, the soils in this unit include: Yellow or Brown Chromosols, Yellow or Brown Sodosols, Grey or Yellow Dermosols, and Grey or Yellow Kandosols.

 

Chromosols are soils that display a strong texture contrast between surface (A) horizons and subsoil (B) horizons. The upper part of the subsoil ranges from slightly acid to alkaline (pH >5.5) but is not sodic. Using the Australian Soil Classification, Chromosols can be grouped further (in to Suborders) based on the color of the upper 20 cm of the subsoil (i.e. Red, Brown, Yellow, Grey and Black). These can be further differentiated based on subsoil characteristics (in to Great Groups) such as the nutrient level capacities and ratios and the presence of carbonate or lime.

A Typic Haplorthod from south-west Poland--lower Silesia region and the Sudetes Mountains. These soils formed in materials weathered from Upper Cretaceous sandstone. (Photo provided by Cezary Kabala, Institute of Soil Science, University of Environmental and Life Sciences, Wroclaw, Poland.)

 

In the US, Typic Haplorthods occur mostly in the northeastern and northwestern parts of the United States as well as Michigan, Wisconsin, Minnesota, West Virginia, and Maryland. They generally support forest vegetation, but some have been cleared for pasture or crop production. The most common crops are small grain, corn for silage, and in Maine potatoes.

 

These are the relatively freely drained Spodosols that either have an albic horizon and a spodic horizon or, under cultivation, commonly have only a spodic horizon below an Ap horizon. The spodic horizon may rest on a lower sequum with an argillic or kandic horizon, on relatively unaltered unconsolidated materials, or on rock. The soil temperature regime is frigid or warmer, and the moisture regime is predominantly udic. Most Haplorthods have, or used to have, forest vegetation, mainly conifers but also hardwoods in some areas. A majority of these soils formed in sandy deposits or in materials weathered from sandstone or quartzite.

 

These soils are classified as Albic Podzols (Arenic, Endoskeletic) by the World Reference Base (WRB).
