While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1. The sign or "target" for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. -
Topic: Soil Classification
Programme: M.Sc.(Environmental Science) Course: Soil Science Semester: IV Code: MSESC4007E04 Topic: Soil Classification Prof. Umesh Kumar Singh Department of Environmental Science School of Earth, Environmental and Biological Sciences Central University of South Bihar, Gaya Note: These materials are only for classroom teaching purpose at Central University of South Bihar. All the data/figures/materials are taken from several research articles/e-books/text books including Wikipedia and other online resources. 1 • Pedology: The origin of the soil , its classification, and its description are examined in pedology (pedon-soil or earth in greek). Pedology is the study of the soil as a natural body and does not focus primarily on the soil’s immediate practical use. A pedologist studies, examines, and classifies soils as they occur in their natural environment. • Edaphology (concerned with the influence of soils on living things, particularly plants ) is the study of soil from the stand point of higher plants. Edaphologist considers the various properties of soil in relation to plant production. • Soil Profile: specific series of layers of soil called soil horizons from soil surface down to the unaltered parent material. 2 • By area Soil – can be small or few hectares. • Smallest representative unit – k.a.

There is disagreement among scientists whether taxonomies are invented (human-made constructs) or are discovered Keywords: (‘‘natural’’ structures) independent of the discipline involved. We believe it would be helpful to study the Soil survey practices nature of taxonomies from different points of view in order to examine questions such as; are there Soil taxonomies common features in all taxonomic systems?, are the systems neutral?, and how are classifications and Power laws data collection (surveys) linked? It is generally accepted that much institutional work on soil Fractals classification systems was nationally biased, especially in terms of practical land management. Mental constructs Information processing Recent studies show that the USDA soil taxonomy has the same mathematical structure as some biological ones that conform to physical laws that dictate and optimize information flow in user friendly retrieval systems. -

Historic agriculture was widespread, physically and chemically altering most southern Piedmont soils. We sampled the granitic gneiss parent material and the overlying 6m soil profile from a historically uncultivated, stable, Ultisol located on the Calhoun Experimental Forest in Union County, SC. Our objectives were 3-fold: (1) to quantify flux rates of 8 elements (Si, Al, Fe, Mg, Ca, Na, K, and Mn) during in-situ soil formation on the southern Piedmont using chemical mass balance equations that reference soil horizons to parent material and meteoric 10Be soil residence times, (2) to characterize the distribution of meteoric 10Be in a highly-weathered Ultisol profile through measurement of other soil properties (including pH, %C, exchangeable cations, KCl acidity, texture, and effective CEC and base saturation) and multivariate analysis, and (3) to estimate Be mobility in soil during granitic gneiss weathering in the southern Piedmont using the mass balance approach described above. -
Standardised Soil Profile Data to Support Global Mapping

Standardised soil profile data to support global mapping and modelling (WoSIS snapshot 2019) Niels H. Batjes, Eloi Ribeiro, and Ad van Oostrum ISRIC – World Soil Information, Wageningen, 6708 PB, the Netherlands Correspondence: Niels H. Batjes ([email protected]) Received: 6 September 2019 – Discussion started: 16 September 2019 Revised: 17 December 2019 – Accepted: 9 January 2020 – Published: 10 February 2020 Abstract. The World Soil Information Service (WoSIS) provides quality-assessed and standardised soil profile data to support digital soil mapping and environmental applications at broadscale levels. Since the release of the first “WoSIS snapshot”, in July 2016, many new soil data were shared with us, registered in the ISRIC data repos- itory and subsequently standardised in accordance with the licences specified by the data providers. Soil profile data managed in WoSIS were contributed by a wide range of data providers; therefore, special attention was paid to measures for soil data quality and the standardisation of soil property definitions, soil property values (and units of measurement) and soil analytical method descriptions. We presently consider the following soil chemi- cal properties: organic carbon, total carbon, total carbonate equivalent, total nitrogen, phosphorus (extractable P, total P and P retention), soil pH, cation exchange capacity and electrical conductivity. We also consider the fol- lowing physical properties: soil texture (sand, silt, and clay), bulk density, coarse fragments and water retention. Both of these sets of properties are grouped according to analytical procedures that are operationally comparable. -
