Keys to Soil Taxonomy by Agriculture Department Pdf
This publication, Keys to Soil Taxonomy, Twelfth Edition, 2014, coincides with the 20th World Congress of Soil Science, to be held on Jeju Island, Korea in June 2014. The Keys to Soil Taxonomy serves two purposes. It provides the taxonomic keys necessary for the classification of soils in a form that can be used easily in the field. It also acquaints users of soil taxonomy with recent changes in the classification system. The twelfth edition of the Keys to Soil Taxonomy incorporates all changes approved since the publication in 1999 of the second edition of Soil Taxonomy: A Basic System of Soil Classification for Making and Interpreting Soil Surveys.

United Arab Emirates Keys to Soil Taxonomy by Shabbir A. Shahid,Mahmoud A. Abdelfattah,Michael A. Wilson,John A. Kelley,Joseph V. Chiaretti Pdf
Central to human life and civilization, soils are an integral part of the physical and cultural environment. Although we may take them for granted, the rise and fall of civilizations is closely linked with the use and abuse of soil and water resources. It is therefore important to evaluate soils for their quality and link them to appropriate uses and services. This book provides information on soil classification and shows how to key out taxa relevant to UAE soils. The latest soil inventory of United Arab Emirates reveals that a rather uniform looking desert landscape has, in fact, a diversity of subsurface features. These features confirm the soil diversity in terms of classification, chemistry, physics, mineralogy, fertility, suitability for different uses and vulnerability to land degradation. United Arab Emirates Keys to Soil Taxonomy presents information for keying out the soils of the United Arab Emirates into separate classes and provides a guide to associated laboratory methods. The classification used predominantly is extracted from the 11th edition of the USDA-NRCS Keys to Soil Taxonomy, and sections relevant to the soils found in the UAE are included here. Primarily, this key is designed to fit the soil system of the United Arab Emirates. Information not found in the USDA key has been added, including criteria and classes for: 1) differentiating anhydritic soils from gypsic soils, 2) identifying “lithic” subgroups for Aquisalids and Haplosalids, 3) identifying “salidic” subgroups within the great groups of Gypsids, Calcids, Psamments, and Orthents, and 4) incorporation of phases for soil taxa. A subsurface diagnostic horizon and mineralogy class (anhydritic), not reported earlier in the world soil literature and, recently found in the UAE, has also been added to the book. The book also offers a mechanism for updating the current soil surveys, and will facilitate the correlation of soils from new surveys in the UAE. Additionally, it will help the international soil science community to converse about UAE soils, and facilitate comparison to soils of other regions. These linkages allow countries with similar mapping and classification procedures and similar soils to transfer agriculture technology without conducting long-term experiments under similar environmental conditions, especially for Gulf Cooperation Council countries (Bahrain, Kuwait, Qatar, Oman, and Saudi Arabia).
Keys to Soil Taxonomy (Eleventh Edition) by U. S. Department of Agriculture,Natural Resources Conservation Service,Soil Survey Staff Pdf
The publication Keys to Soil Taxonomy serves two purposes. It provides the taxonomic keys necessary for the classification of soils in a form that can be used easily in the field. It also acquaints users of the taxonomic system with recent changes in the system. The eleventh edition of the Keys to Soil Taxonomy incorporates all changes approved since the publication of the second edition of Soil Taxonomy: A Basic System of Soil Classification for Making and Interpreting Soil Surveys (1999). One of the most significant changes in the eleventh edition is the addition of the suborders Wassents and Wassists for subaqueous Entisols and Histosols.

The Canadian System of Soil Classification by Canadian Agricultural Services Coordinating Committee. Soil Classification Working Group,National Research Council Canada,Canada. Agriculture and Agri-Food Canada. Research Branch Pdf
This treatise begins with an introduction on the history of soil classification in Canada and discussion of the rationale for soil taxonomy. It then defines such terms as soil, pedon, and soil horizons before outlining the classification system along with identification keys. Chapters 4 through 13 describe the characteristics of the various soil orders and include information on distinguishing soils of one order from soils of other orders. Chapter 14 outlines criteria & guidelines used in differentiating classes in soil families and soil series categories. Chapter 15 provides information on distinguishing soil phases. Chapter 16 correlates Canadian soil taxonomy with other classification systems. Chapter 17 summarizes the main terminology used to describe soils at the landscape and pedon scales. The final chapter provides a system of landform classification for soil mapping.
