Kalkaska Sand
Kalkaska sand is the official state soil of the U.S. state of Michigan. Kalkaska sand was identified in 1927 and named after Kalkaska County located in the northern Lower Peninsula of Michigan. This soil is a multi-layer soil composed of humus, light sand, dark sand, and yellowish sand. It is classified as a spodosol. The distinctive sand layers can range from black to yellowish-brown and are commonly 2 to 4 feet (0.6 to 1.2 m) deep. Kalkaska sand is well-drained and effectively filters water. This makes it a valuable asset in forestry and certain types of agriculture. It is also largely responsible for the remarkable water quality of lakes and rivers located in areas of the state where these soils are abundant. Kalkaska sand is one of more than 500 soils found in Michigan. Unique to the state, Kalkaska Sand covers nearly 1 million acres (4,000 km2) in 29 Upper and Lower Peninsula counties. It was designated as the state soil of Michigan in 1990. Kalkaska soils are c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soil Classification
Soil classification deals with the systematic categorization of soils based on distinguishing characteristics as well as criteria that dictate choices in use. Overview Soil classification is a dynamic subject, from the structure of the system, to the definitions of classes, to the application in the field. Soil classification can be approached from the perspective of soil as a material and soil as a resource. Inscriptions at the temple of Horus at Edfu outline a soil classification used by Tanen to determine what kind of temple to build at which site. Ancient Greek scholars produced a number of classification based on several different qualities of the soil. Engineering Geotechnical engineers classify soils according to their engineering properties as they relate to use for foundation support or building material. Modern engineering classification systems are designed to allow an easy transition from field observations to basic predictions of soil engineering properties and ...

Symbols Of Michigan
A symbol is a mark, sign, or word that indicates, signifies, or is understood as representing an idea, object, or relationship. Symbols allow people to go beyond what is known or seen by creating linkages between otherwise different concepts and experiences. All communication is achieved through the use of symbols: for example, a red octagon is a common symbol for " STOP"; on maps, blue lines often represent rivers; and a red rose often symbolizes love and compassion. Numerals are symbols for numbers; letters of an alphabet may be symbols for certain phonemes; and personal names are symbols representing individuals. The academic study of symbols is called semiotics. In the arts, symbolism is the use of a concrete element to represent a more abstract idea. In cartography, an organized collection of symbols forms a legend for a map. Etymology The word ''symbol'' derives from the late Middle French masculine noun , which appeared around 1380 in a theological sense signifying a ...

Geology Of Michigan
Michigan consists of two peninsulas surrounded primarily by four of the Great Lakes and a variety of nearby islands. The Upper Peninsula of Michigan, Upper Peninsula is bounded on the southwest by Wisconsin, and the Lower Peninsula of Michigan, Lower Peninsula is bounded on the south by Indiana and Ohio. Both land masses are also separated from the Canadian province of Ontario by waterways of the Great Lakes, and from each other by the Straits of Mackinac. Because its land is largely surrounded by the Great Lakes, which flow into the Saint Lawrence River, Michigan is the only U.S. state whose streams and rivers are almost entirely within the Great Lakes-St. Lawrence watershed. Michigan's territorial waters include roughly half each of Lake Superior, Lake Michigan, and Lake Huron, and smaller areas of Lake St. Clair and Lake Erie. It includes an estimated 11,000 inland lakes. It encompasses of land, of Great Lakes waters, and of inland waters. Its territorial waters are second ...

Soil In The United States
The US soil taxonomic hierarchy includes orders, suborders, great groups, subgroups, families and series, with each series representing a unique kind of soil. In the United States, over 19,000 soil series have been identified.Soil Survey Staff. 1999. Soil Taxonomy. 2nd Ed. USDA Natural Resources Conservation Service. Agric. Handbook 436. 871 pp. Composition The percentages of land area (in the US and associated territories, etc.) occupied by soils of the twelve orders have been estimated as: Regional distribution Alfisols and Inceptisols occur widely in the US, but the circumstances of their occurrence would be difficult to characterize briefly. The Alfisols have a subsurface ("B") horizon characterized by phyllosilicate clay accumulation (suggesting illuviation of such clay from above). The Inceptisols have a weakly developed B horizon as a consequence of weathering and/or other processes. Andisols are found in areas where soils have formed in certain kinds of volcanic e ...

Pedology
Pedology (from Greek: πέδον, ''pedon'', "soil"; and λόγος, ''logos'', "study") is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment. Pedology is often seen as one of two main branches of soil inquiry, the other being edaphology which is traditionally more agronomically oriented and focuses on how soil properties influence plant communities (natural or cultivated). In studying the fundamental phenomenology of soils, e.g. soil formation (aka pedogenesis), pedologists pay particular attention to observing soil morphology and the geographic distributions of soils, and the placement of soil bodies into larger temporal and spatial contexts. In so doing, pedologists develop systems of soil classification, soil maps, and theories for characterizing temporal and spatial interrelations among soils. There are a few ...

List Of U
A list is a set of discrete items of information collected and set forth in some format for utility, entertainment, or other purposes. A list may be memorialized in any number of ways, including existing only in the mind of the list-maker, but lists are frequently written down on paper, or maintained electronically. Lists are "most frequently a tool", and "one does not ''read'' but only ''uses'' a list: one looks up the relevant information in it, but usually does not need to deal with it as a whole". Lucie Doležalová,The Potential and Limitations of Studying Lists, in Lucie Doležalová, ed., ''The Charm of a List: From the Sumerians to Computerised Data Processing'' (2009). Purpose It has been observed that, with a few exceptions, "the scholarship on lists remains fragmented". David Wallechinsky, a co-author of '' The Book of Lists'', described the attraction of lists as being "because we live in an era of overstimulation, especially in terms of information, and lists help ...

Soil Types
A soil type is a taxonomic unit in soil science. All soils that share a certain set of well-defined properties form a distinctive soil type. Soil type is a technical term of soil classification, the science that deals with the systematic categorization of soils. Every soil of the world belongs to a certain soil type. Soil type is an abstract term. In nature, you will not find soil types. You will find soils that belong to a certain soil type. In hierarchical soil classification systems, soil types mostly belong to the higher or intermediate level. A soil type can normally be subdivided into subtypes, and in many systems several soil types can be combined to entities of higher category. However, in the first classification system of the United States (Whitney, 1909), the soil type was the lowest level and the mapping unit. For the definition of soil types, some systems use primarily such characteristics that are the result of soil-forming processes (pedogenesis). An example is th ...

USDA Soil Taxonomy
USDA soil taxonomy (ST) developed by the United States Department of Agriculture and the National Cooperative Soil Survey provides an elaborate Soil classification, classification of soil types according to several parameters (most commonly their properties) and in several levels: ''Order'', ''Suborder'', ''Great Group'', ''Subgroup'', ''Family'', and ''Soil series, Series''. The classification was originally developed by Guy D. Smith, Guy Donald Smith, former director of the U.S. Department of Agriculture's soil survey investigations. Discussion A taxonomy is an arrangement in a systematic manner; the United States Department of Agriculture, USDA soil taxonomy has six levels of classification. They are, from most general to specific: order, suborder, great group, subgroup, family and series. Soil properties that can be measured quantitatively are used in this classification system – they include: depth, moisture, temperature, texture, structure, cation exchange capacity, base ...

Natural Resources Conservation Service
Natural Resources Conservation Service (NRCS), formerly known as the Soil Conservation Service (SCS), is an agency of the United States Department of Agriculture (USDA) that provides technical assistance to farmers and other private landowners and managers. Its name was changed in 1994 during the presidency of Bill Clinton to reflect its broader mission. It is a relatively small agency, currently comprising about 12,000 employees. Its mission is to improve, protect, and conserve natural resources on private lands through a cooperative partnership with State governments of the United States, state and Local government in the United States, local agencies. While its primary focus has been agriculture, agricultural lands, it has made many technical contributions to soil surveying, soil classification, classification, and water quality improvement. One example is the Conservation Effects Assessment Project (CEAP), set up to quantify the benefits of agricultural conservation efforts pr ...
