This book was released on 2013-02-15 with total page 875 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the world’s population continues to expand, maintaining and indeed increasing agricultural productivity is more important than ever, though it is also more difficult than ever in the face of changing weather patterns that in some cases are leading to aridity and desertification. The absence of scientific soil inventories, especially in arid areas, leads to mistaken decisions about soil use that, in the end, reduce a region’s capacity to feed its population, or to guarantee a clean water supply. Greater efficiency in soil use is possible when these resources are properly classified using international standards. Focusing on arid regions, this volume details soil classification from many countries. It is only once this information is properly assimilated by policymakers it becomes a foundation for informed decisions in land use planning for rational and sustainable uses.

Download or read book The Canadian System of Soil Classification written by Canadian Agricultural Services Coordinating Committee. Soil Classification Working Group and published by NRC Research Press. This book was released on 1998 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Soil Science Agricultural and Environmental Prospectives written by Khalid Rehman Hakeem and published by Springer. This book was released on 2016-08-01 with total page 439 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil is the most important natural non-renewable resource developed over a longer period of time due to weathering of rocks and subsequently enrichment of organic matter. Soil provides habitat for numerous microorganisms and serves as a natural medium for plant growth, thereby providing the plants with anchorage, nutrients and water to sustain the growth. Soil also serves as a universal sink for all types of pollutants, purifies ground water and is a major reserve of carbon in the universe. The role of soils to provide ecosystem services, maintenance of environmental/human health and ensuring the food security makes it as the most important and basic natural resource. Soil Science helps us to elaborate and understand how the soils provide all these services. Soil Science also provides us the basic knowledge dealing with the origin of the soil parent material, weathering of parent material and the formation of soils, morphological, physico-chemical and biological features of soils, classification of soils and role of soils in the provision and maintenance of ecosystem services, food security and environmental quality. This book encompasses the various processes, functions and behaviour of soils very comprehensively to acquaint the students of soil, plant and environmental sciences about their role to perform different agricultural and environmental functions.
Download or read book Keys to Soil Taxonomy written by and published by . This book was released on 2020-05-31 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Keys to Soil Taxonomy Twelfth Edition 2014 By Soil Survey Staff (USDA) 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. The authors of the Keys to Soil Taxonomy are identified as the "Soil Survey Staff." This term is meant to include all of the soil classifiers in the National Cooperative Soil Survey program and in the international community who have made significant contributions to the improvement of the taxonomic system. The authors plan to continue issuing updated editions of the Keys to Soil Taxonomy as changes warrant new editions. One change in this edition is recognizing the occurrence of anhydrite (CaSO4 ) in soils with the addition of a new diagnostic horizon, a new mineralogy class, and new Anhydritic subgroups for use in soil survey. These are significant improvements to soil taxonomy which resulted from international collaboration with soil scientists of the United Arab Emirates, where the soils with anhydrite were discovered. Pedologists in Argentina have also contributed to this edition with amendments to improve classification of the Mollisols of the Pampean region and to recognize the abrupt textural change in more soils having this important genetic characteristic. This is a re-paperback book version of the "Keys to Soil Taxonomy Twelfth Edition (2014)". Full version, All Chapters included. This publication is available (Electronic version) in the official website of the U.S. Department of Agriculture.

Download or read book Guidelines for Soil Description written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2006 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soils are affected by human activities, such as industrial, municipal and agriculture, that often result in soil degradation and loss. In order to prevent soil degradation and to rehabilitate the potentials of degraded soils, reliable soil data are the most important prerequisites for the design of appropriate land-use systems and soil management practices as well as for a better understanding of the environment. The availability of reliable information on soil morphology and other characteristics obtained through examination and description of the soil in the field is essential, and the use of a common language is of prime importance. These guidelines, based on the latest internationally accepted systems and classifications, provide a complete procedure for soil description and for collecting field data. To help beginners, some explanatory notes are included as well as keys based on simple test and observations.--Publisher's description.

This book was released on 2018-07-20 with total page 203 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication is a revised and updated version of World Soil Resources Reports No. 84 and 103 and presents the international soil classification system. Every soil in the world can be allocated to one of the 32 Reference Soil Groups as defined in this document, and can further be characterized by a set of qualifiers. The resulting soil name provides information on soil genesis, soil ecological function and soil properties relevant for land use and management. The same system, refined slightly, may be used to name the units of soil map legends, thereby providing comprehensive spatial information. By accommodating national soil classification systems, the World Reference Base facilitates the worldwide correlation of soil information.
