   There are many different kinds and types of soils. Each has certain characteristics including a specific color and composition.  
   http://42explore.com/dirt.htm
   
   Extractions: Easier - Soil is the loose top layer of our planet's crust. It is dirt or earth in which plant life can grow. Harder - Soil covers a major portion of the earth's land surface. It is an important natural resource that either directly or indirectly supports most of the planet's life. Life here depends upon soil for food. Plants are rooted in soil and obtain needed nutrients there. Animals get their nutrients from plants or from other animals that eat plants. Many animals make their homes or are sheltered in the soil. Microbes in the soil cause the breakdown and decay of dead organisms, a process that in turn adds more nutrients to the soil. Soil is a mixture of mineral and organic materials plus air and water. The contents of soil varies in different locations and is constantly changing. There are many different kinds and types of soils. Each has certain characteristics including a specific color and composition. Different kinds of soils support the growth of different types of plants and also determine how well that plant life grows. Soil is formed slowly, but can be easily destroyed. Therefore, soil conservation is important for continued support of life.

    Extractions: Each of the world's soils is assigned to one of the twelve orders, largely on the basis of soil properties. The properties are a result of the five soil forming factors acting on the parent material over time. Emphasis for placing a soil into a soil Order is determined by the presence or absence of the diagnostic features. It is interesting to note that other countries may have different classification systems, but most are similar to the system used in the USA. The United Nations FAO Soil Map of the World, uses a different system that has 31 major soil groups. http://www.fao.org/ag/agl/agll/wrb/wrbmaps/htm/soilres.htm A summary of characteristics, a sample profile, and the the diagnostic features present are given for each of the 12 soil orders. Be sure to look at the map for each order to see its location in the U.S.A. US SOILS MAP . You will also need to know where the orders are located in the world. World Soils Map Ent isols : Soils that have little or slight development and properties that reflect their parent material ( ent root from the word recent ). They include soils on steep slopes, flood plains, and sand dunes. They also form on very resistant rock or deep deposits of sand. They occur in many environments. They have an ochric and none diagnostic features. The typical profile sequence would be A, C, or A, Bw, C (where the Bw is not cambic due to being too sandy).

    Extractions: (Redirected from United Kingdom soil classification system Jump to: navigation search This document is designed to accompany the national soil map legend and briefly describes the constituent soil associations of the 1:250 000 (quarter inch to 1 mile) soil map of England and Wales held by Cranfield University. The soil classification, outlined briefly below, is treated more fully in Avery (1980) and in the revised classification of soil series by Clayden and Hollis (1984). The national soil map (or ‘Natmap’) is based on published soil maps which cover a quarter of the land at scales of 1:25 000, 1:63 360 or 1:100 000 and on reconnaissance mapping of previously unsurveyed areas. The legend shows geographic soil associations identified by the most frequently occurring soil series and by combinations of ancillary series. The map units are further identified by number codes and are coloured by dominant soil subgroups (or groups), of which sixty seven are recognised. The numbers of each code indicate the predominant major soil group, group and subgroup Thus, association 651a is dominated by soils of the Belmont series belonging to subgroup 6.51, the

    Extractions: Soils Home About Us Soil Survey Soil Use ... Contact Us Search Soils All NRCS Sites for Click here to go directly to the list of states. A state soil is a soil that has special significance to a particular state. Each state in the United States has selected a state soil, twenty of which have been legislatively established. These �Official State Soils� share the same level of distinction as official state flowers and birds. Also, representative soils have been selected for Puerto Rico and the Virgin Islands. Areas with similar soils are grouped and labeled as soil series because their similar origins, chemical, and physical properties cause the soils to perform similarly for land use purposes. A soil series name generally is derived from a town or landmark in or near the area where the soil was first recognized. Each series consists of soils having major horizons that are similar in color, texture, structure, reaction, consistence, mineral and chemical composition, and arrangement in the soil profile. A soil profile is the sequence of natural layers, or horizons, in a soil. It extends from the surface downward to unconsolidated material. Most soils have three major horizons, called the surface horizon, the subsoil, and the substratum. The surface layer has the maximum accumulation of organic matter and is the horizon of maximum leaching of clay minerals and of iron and aluminum oxides. Some soils have a subsurface layer below the surface layer.

    PRINCIPAL SURFACE SOIL CLASSES 1. Loam —When rubbed between the thumb and fingers, approximately equal influence of sand, silt, and clay is felt.  
    http://ag.arizona.edu/pubs/garden/mg/soils/principal.html
    
    Extractions: Clay Sandy loam Silt loam Silty clay loam Clay loam In general, the finer the texture: the more difficult a soil is to work or till, the greater the water holding capacity, the slower water will enter and move through the soil profile, the more difficult plant root penetration, the more readily surface soil will crust, and the more nutrient rich the soil. Regardless of textural class, all soils in Arizona contain sand, silt, and clay, although the amount of a particular particle class may be small. Other textural designations of surface soils are sands, loamy sands, sandy clay loams,silty clay, siltss, and clays. In each textural class there is a range in the amount of sand, silt, or clay that class may contain. These ranges can be expressed as a percentage for each soil texture. The percentages converge on the soil triangle to determine soil textural classes. The composition of each textural class does not allow for overlap from one class to another.

    Extractions: One of the identifying characteristics of wetlands, from both ecological and statutory points of view, is the presence of hydric, or wet, soils. Hydric soils are defined by the U.S.D.A. Natural Resources Conservation Service (NRCS) as "soils that formed under conditions of saturation, flooding or ponding long enough during the growing season to develop anaerobic conditions in the upper part". Redoximorphic features, the third factor, include gray layers and gray mottles both of which occur when iron compounds are reduced by soil microbes in anaerobic soils. Iron, in its reduced form, is mobile and can be carried in the groundwater solution. When the iron and its brown color are thus removed, the soils show the gray color of their sand particles. The anaerobic, reduced zones can be recognized by their gray, blue, or blue?gray color. The mobilized iron tends to collect in aerobic zones within the soil where it oxidizes, or combines with additional oxygen, to form splotches of bright red?orange color called mottles. The mottles are most prevalent in the zones of fluctuating water and thus help mark the seasonal high water table.
