regi.tankonyvtar.hu/hu/tartalom/tamop425/0032_talajtan/ch...
PHAEOZEMS: Soil with a deep, dark surface horizon that is rich in organic matter without secondary calcium carbonate concentrations within 1m (from the Greek, phaios, meaning dusk and the Russian, zemlja, meaning earth or land). Phaeozems are found in wet steppe (prairie) regions and are much like Chernozems and Kastanozems but more intensively leached in wet seasons. Consequently, they have a dark,humus-rich surface horizon and have no secondary carbonates in the upper metre of soil. Commonly used international names are Brunizems (Argentina, France), Parabraunerde-Tschernozems (Germany) and Aquolls in the order of the Mollisols (Soil Taxonomy) They cover 3 percent of Europe.
The current Hungarian Soil Classification System (HSCS) was developed in the 1960s, based on the genetic principles of Dokuchaev. The central unit is the soil type grouping soils that were believed to have developed under similar soil forming factors and processes. The major soil types are the highest category which groups soils based on climatic, geographical and genetic bases. Subtypes and varieties are distinguished according to the assumed dominance of soil forming processes and observable/measurable morphogenetic properties.
A representative soil profile of Dina cobbly silty clay loam, in an area of Dina-Eckrant complex, 1 to 8 percent slopes. The mollic epipedon is 20 centimeters thick. The red coatings on the rock fragments are iron oxides and clay. .(Soil Survey of Edwards and Real Counties, Texas; by Wayne J. Gabriel, Dr. Lynn E. Loomis, and James A. Douglass II Natural Resources Conservation Service)
The Dina series consists of moderately deep, well drained, moderately slowly permeable soils that formed in clayey residuum over limestone bedrock. These soils are on nearly level to gently sloping upland plateaus and ridges. Slopes range from 0 to 6 percent.
TAXONOMIC CLASS: Clayey-skeletal, smectitic, thermic Pachic Paleustolls
Solum thickness is 20 to 40 inches over limestone bedrock. Thickness of the mollic epipedon is 20 to 36 inches. Coarse fragments are angular or rounded chert and limestone pebbles, cobbles, and stones. Chert pebbles on the soil surface range from 5 to 15 percent. Chert and limestone cobbles and stones 3 to 24 inches in diameter comprise 2 to 45 percent by volume of any horizon. Reaction is medium acid through slightly alkaline.
USE AND VEGETATION: Used for rangeland. Native grasses include sideoats grama, Texas grama, silver bluestem, curlymesquite, plains lovegrass, and Texas wintergrass. Woody vegetation includes live oak, mesquite, hackberry, lotebush condalia, whitebrush, agarito, and pricklypear.
DISTRIBUTION AND EXTENT: Southwest Texas in the Central Edwards Plateau. The series is of moderate extent.

A representative soil profile of Premont fine sandy loam, 0 to 3 percent slopes. This soil is used for crop and forage production in the county. The rounded shape and the downward weathering pattern of the calcium carbonates nodules at a depth of 1 meter, suggests the parent material was deposited by alluvial processes. (Soil Survey of Duval County, Texas; by John L. Sackett III, Natural Resources Conservation Service)
The Premont series consists of very deep, moderately permeable, well drained soils that have formed in loamy sediments over calcareous loamy alluvium of Quaternary age. These nearly level to gently sloping soils are on crests on paleoterraces. Slope ranges from 0 to 3 percent. The mean annual temperature is about 22.2 degrees C (72 degrees F), and the mean annual precipitation is about 660 mm (26 in).
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, hyperthermic Typic Haplustalfs
Soil Moisture: An ustic moisture regime. The soil moisture control section is dry in some or all parts for more than 90 but less than 180 cumulative days in normal years. June through August and December through February are the driest months. These soils are intermittently moist in September through November and March through May.
Mean annual soil temperature: 22.2 to 23.4 degrees C (72 to 74 degrees F).
Depth to secondary calcium carbonates: 74 to 152 cm (29 to 60 in).
Particle-size control section (weighted average): Clay content: 17 to 32 percent.
Some pedons have mollic colors but do not have enough organic carbon to meet the requirements for a mollic epipedon.
USE AND VEGETATION: The major uses are crop production, livestock grazing, and wildlife habitat. Grasses present include false rhodesgrass, Kleberg bluestem, plains bristlegrass, shortspike windmillgrass, and guineagrass. Woody vegetation consists of mesquite, catclaw, elbowbush, limepricklyash, pricklypear, granjeno, and tasajillo. Crops grown include grain sorghum, watermelons and cotton. Sandy Loam (R083AY407TX).
DISTRIBUTION AND EXTENT: Northern Rio Grande Plain (MLRA 83A in LRR I) of southern Texas. The series is of moderate extent.
The Premont soils were formerly included in the Delfina series. Future study is needed to verify the calcic horizon of these soils. The calcium carbonate masses appear to be degrading petrocalcic fragments and are being removed from the soil matrix. This is characterized by the sharp boundaries of the soft material surrounding, in some cases, nodules that vary in size. These are mostly in the lower materials below the lithologic discontinuity.

A representative soil profile of a Typic Kanhapludult in China.
The central concept of the Typic subgroup of Kanhapludults is fixed on freely drained soils that are more than 50 cm deep to a lithic contact.
Typic Kanhapludults are of large extent in the Southeastern United States. The natural vegetation consisted of forest plants. Slopes range from nearly level to steep. Where slopes are suitable, many of the soils are used as cropland. The steeper soils are used as forest. Some of the soils are used as pasture or homesites.

A soil profile of a Haplargid in New Mexico. The soil exhibits development only in about the upper 40 cm, where an ochric epipedon (between 0 and 10 cm) is underlain by an argillic horizon (10 to 40 cm). Below this depth, the soil retains the original stratified character of the alluvial deposits from which it formed. (Soil Survey Staff. 2015. Illustrated guide to Soil Taxonomy. U.S. Department of Agriculture, Natural Resources Conservation Service, National Soil Survey Center, Lincoln, Nebraska)
Haplargids have only an argillic (clay accumulation) horizon. They commonly have some calcium carbonate accumulations within or below the argillic horizon. Haplargids commonly occur on late-Pleistocene surfaces or sediments.
Argids are the Aridisols that have an argillic (clay accumulation) or natric (high levels of illuvial clay and sodium) horizon. In many Aridisols, the low water flux and high concentration of salts hinder clay illuviation. The presence of an argillic horizon is therefore commonly attributed to a moister paleoclimate (although there is evidence that clay illuviation occurred during the Holocene in arid soils). In semiarid areas (where the soil moisture regime grades to ustic or xeric), clay translocation commonly is more evident. Most Argids occur in North America. A few have been recognized in the deserts of North Africa and the Near East.

The Wake series consists of excessively drained, shallow, sandy soils on uplands of the Southern Piedmont. They formed in residuum weathered from igneous and high-grade metamorphic rocks such as granite and gneiss.
TAXONOMIC CLASS: Mixed, thermic Lithic Udipsamments
USE AND VEGETATION: Mostly in mixed hardwood forest of post oak, blackjack oak, northern red oak, and hickory along with shortleaf pine, Virginia pine and loblolly pine. Small areas are used for corn, small grain, orchards, and pasture.
DISTRIBUTION AND EXTENT: Piedmont of North Carolina, and possibly Alabama, Georgia, South Carolina, and Virginia. The series is of small extent.

This soil is mostly on dunes, but is also found on level to undulating sand sheets overlying alluvial plains. This soil is somewhat excessively drained. Median measured saturated hydraulic conductivity class for the surface layer is very high.
This soil is used mostly for rangeland grazing for camels. In some areas the dunes have been leveled for building site development. Commonly described vegetation species include Calotropis procera, Citrullus colocynthis Haloxylon salicornicum, Cyperus conglomeratus, and Prosopis cineraria. Vegetative cover is mostly less than 5%.
This soil occurs extensively throughout the western and central two-thirds of the soil survey area. It is the most extensive soil. The main distinguishing feature of this soil is the thick sandy profile of eolian origin. It has limited water and nutrient holding capacity and is subject to wind erosion after disturbance. Steep slopes and uneven topography limit its suitability for irrigated agriculture, but land leveling can overcome this limitation. Salinity is generally low in these soils, and gravels are absent, making it a desirable material for soil replacement for uses such as intensive date palm plantations and landscaping around building sites.

Peds are aggregates of soil particles form as a result of pedogenic processes; this natural organization of particles forms discrete units separated by pores or voids. The term is generally used for macroscopic (visible; i.e. greater than 1 mm in size) structural units when observing soils in the field. Soil peds should be described when the soil is dry or slightly moist, as they can be difficult to distinguish when wet.
In platy structure, the units are flat and platelike. They are generally oriented horizontally. A special form, lenticular platy structure, is recognized for plates that are thickest in the middle and thin toward the edges. Platy structure is usually found in subsurface soils that have been subject to leaching or compaction by animals or machinery. The plates can be separated with little effort by prying the horizontal layers with a pen knife. Platy structure tends to impede the downward movement of water and plant roots through the soil.
There are five major classes of macrostructure seen in soils: platy, prismatic, columnar, granular, and blocky. There are also structureless conditions. Some soils have simple structure, each unit being an entity without component smaller units. Others have compound structure, in which large units are composed of smaller units separated by persistent planes of weakness.

A soil profile of a well drained, gravelly Humustept in the Philippines. The soil formed in stratified layers of material, including volcanic ash. It has a dark, humus-rich umbric epipedon about 28 cm thick. Below this epipedon is a cambic horizon that extends to a depth of about 55 cm. (Soil Survey Staff. 2015. Illustrated guide to Soil Taxonomy. U.S. Department of Agriculture, Natural Resources Conservation Service, National Soil Survey Center, Lincoln, Nebraska)
Humustepts have a mollic (rich in humus and bases) or umbric (humus-rich with low base saturation) epipedon. Parent materials are mostly residuum, colluvium, or alluvium in mountain settings. Some have been influenced by volcanic ash. These soils commonly have a brownish cambic (minimal soil development) subsoil horizon. Some have root-limiting bedrock or a dense, compact layer in the profile. In the United States, Humustepts are found mostly in coastal California and in Hawaii.

This soil is on level to gently undulating alluvial plains and interdunal deflation plains. This soil is somewhat excessively drained. Median measured saturated hydraulic conductivity class
for the surface layer is high.
This soil is mostly used for rangeland grazing for camels. In areas where water is available, small farms have been developed. Where water resources have been depleted, cultivated lands are idle and returning to natural vegetation. Commonly described vegetation species include Acacia Tortilis, Calotropis procera, and Haloxylon salicornicum. Vegetative cover is 2 to 10%.
This soil is on sandy alluvial plains and interdunal deflation plains in the central part of the soil
survey area, generally near the eastern edge of the dune/alluvial plain interface. The main distinguishing feature of this soil is the sandy textures with increasing gravel content with depth. Accumulations of calcium carbonate are in the subsoil. A desert pavement of fine to medium surface gravel provides some protection against wind erosion, but if disturbed, wind erosion can become a problem. Although the soil has limited water and nutrient holding capacity, where quality water is available it can be farmed successfully
Strong structure is well formed from distinct aggregates that are durable and quite evident in undisturbed soil. When removed from the profile, the soil material consists very largely of entire aggregates and includes few broken ones and little or no non-aggregated material.
A representative soil profile of Graycalm sand, which formed in sandy outwash. (Soil Survey of Alpena County, Michigan
By Thomas E. Williams, Michigan Department of Agriculture)
The Graycalm series consists of very deep, somewhat excessively drained soils formed in sandy glaciofluvial deposits on moraines, kames, stream terraces, outwash plains, and glacial drainage channels. Slope ranges from 0 to 70 percent. Mean annual precipitation is about 760 mm (30 inches), and mean annual temperature is about 6.7 degrees C (44 degrees F).
TAXONOMIC CLASS: Isotic, frigid Lamellic Udipsamments
USE AND VEGETATION: A large part is in forestland. Forest vegetation consists chiefly of northern red oak with some white pine in the southern extent of the soil, and jack pine and scrub oak in the northern extent. A small part is cropped to small grains, corn, or hay.
DISTRIBUTION AND EXTENT: MLRAs 57, 88, 90A, 90B, 93A, 94A, 94C, 96, and 98 in the central and northern part of Lower Michigan, north-central part of Minnesota, and northern Wisconsin. The type location is in MLRA 94A. The series is of large extent.

A representative soil profile of the Enosburg series. (Photo provided by Jim Turenne; USDA-NRCS; New England Soil Profiles)
The Enosburg series consists of very deep, poorly drained soils that formed in sandy glaciofluvial or aeolian deposits underlain by loamy estaurine or glaciolacustrine deposits. They are on glacial lake plains and glacial outwash areas. Permeability is rapid in the surface layer and upper part of the substratum and moderately slow or slow in the lower part of the substratum. Slope ranges from 0 to 8 percent. Mean annual precipitation is about 34 inches and mean annual temperature is about 45 degrees F.
TAXONOMIC CLASS: Sandy over loamy, mixed, active, nonacid, mesic Aeric Epiaquents
Depth to the loamy layers ranges from 16 to 34 inches. Depth to bedrock, skeletal, or coarse textured layers is greater than 60 inches. Rock fragments range from 0 to 5 percent. Some subhorizons have up to 20 percent rock fragments. Reaction ranges from very strongly acid to slightly acid in the surface layer and upper part of the substratum and from moderately acid to neutral in the lower part of the substratum.

story: Isaiah gave Erika a tour of one of our sites were we helped to establish a pollinator hedgerow because Erika had never seen one before and this is one of the conservation practices she will be including in her study to document how much Carbon is stored in the soil at various ages with various conservation practices. It was a beautiful morning and a fun, collaborative time!

The soil survey of the Northern Emirates (Fujairah, Sharjah, Umm Al Quwain, Ras Al Khaimah, and Ajman), United Arab Emirates (UAE) was conducted during 2010 – 2012. The Environment Agency – Abu Dhabi (EAD) in partnership with the Ministry of Environment and Water (MOEW) implemented the Soil Survey through GRM International. The project was funded by the Abu Dhabi Executive Council, and its objective was to develop a digital soil information repository to aid in broad land-use planning and agricultural expansion in the Northern Emirates.
Information from the soil survey is expected to be used by various groups, including the agricultural farming community, decision makers, land-use planners, officials, engineers, and environmental impact assessors. Conservationists and specialists in recreation, wildlife management, waste disposal, and pollution control will also use the soil information to help understand, protect and enhance the environment.

Fluvaquentic Endoaquepts.—These soils have either 0.2 percent or more organic carbon (Holocene age) at a depth of 125 cm below the mineral soil surface or an irregular decrease in organic-carbon content (Holocene age) between a depth of 25 cm and either a depth of 125 cm below the mineral soil surface or a densic, lithic, or paralithic contact, whichever is shallower. They also have slopes of less than 25 percent. These soils are extensive in the United States. They are on flood plains in all parts of the country, except for the coldest and the driest parts. The native vegetation is mostly water-tolerant trees and grasses. Some of these soils are used as forest, and some have been cleared and artificially drained and are used as cropland or pasture.

A representative soil profile of the Rexburg series in Idaho.
The Rexburg series consists of deep and very deep, well drained soils that formed in loess and silty alluvium derived from loess. They are on loess covered fan terraces, foothills, and basalt plains. Slopes are 0 to 60 percent. The mean annual precipitation is about 14 inches and the mean annual temperature is about 44 degrees F.
TAXONOMIC CLASS: Coarse-silty, mixed, superactive, frigid Calcic Haploxerolls
Mean annual soil temperature - 40 to 47 degrees F
Particle-size control section - 8 to 18 percent clay
Thickness of the mollic epipedon - 12 to 20 inches
Depth to the calcic horizon - 18 to 35 inches
USE AND VEGETATION: This Rexburg soil is used mainly for nonirrigated and irrigated cropland. The potential natural vegetation is mainly mountain big sagebrush and bluebunch wheatgrass.
DISTRIBUTION AND EXTENT: Southeastern Idaho. The series is extensive.

A representative soil profile of the Flaco extremely : gravelly coarse sand, 1 to 3 percent slopes. (Soil Survey of Wupatki National Monument, Arizona; by James M. Harrigan, Natural Resources Conservation Service)
The Flaco series consists of moderately deep, well drained, moderately slowly permeable soils that formed in alluvium and windblown sediments derived from basalt. Flaco soils are on old basalt capped mesas. Slope is 0 to 15 percent. Mean annual precipitation is about 11 inches and mean annual air temperature is about 53 degrees F.
TAXONOMIC CLASS: Fine-loamy, mixed, superactive, mesic Ustic Calciargids
Soil moisture: Ustic aridic soil moisture regime
Depth to bedrock: 20 to 40 inches
Particle-size control section: 18 to 35 percent clay
USE AND VEGETATION: Flaco soils are used for livestock grazing. Present native vegetation is blue grama, galleta, winterfat, juniper and cholla cactus.
DISTRIBUTION AND EXTENT: The series is of small extent in westcentral New Mexico and eastcentral Arizona. MLRA 35.

This soil is on alluvial plains. This soil is well drained. Median measured saturated hydraulic conductivity class for the surface layer is high.
This soil is commonly used for farming including fruits, vegetables, date palms, and animal fodder. A few previously farmed areas are now idle. The area being built-up for housing, roads, and business is increasing. Some areas are in natural vegetation. Commonly described vegetation species include Acacia tortilis, Haloxylon salicornicum, Prosopis cineraria, and Prosopis juliflora. Vegetation cover is 5 to 40%.
This soil is in the north-central part of the soil survey area, generally between Khatt and Ras Al
Khaimah. The main distinguishing feature of this soil is the relatively fine texture as compared to most other soils in the survey area, as well as the presence of a calcic subsoil horizon with elevated sodium levels. Where irrigation water is available, this soil is well adapted to agricultural use for most crops grown in the area. In areas with loam or silt loam surface layers, care should be taken to manage salt and sodium levels properly to avoid deterioration of soil structure resulting in restricted water infiltration rates.
