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.

Download or read book World reference base for soil resources 2014 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. 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.

Download or read book Soils of Tropical Forest Ecosystems written by Andreas Schulte and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: An understanding of the characteristics and the ecology of soils, particularly those of forest ecosystems in the humid tropics, is central to the development of sustainable forest management systems. The present book examines the contribution that forest soil science and forest ecology can make to sustainable land use in the humid tropics. Four main issues are addressed: characteristics and classification of forest soils, chemical and hydrological changes after forest utilization, soil fertility management in forest plantations and agroforestry systems as well as ecosystem studies from the dipterocarp forest region of Southeast Asia. Additionally, case studies include work from Guyana, Costa Rica, the Philippines, Malaysia, Australia and Nigeria.

Download or read book Encyclopedia of Soil Science written by Ward Chesworth and published by Springer Science & Business Media. This book was released on 2007-11-22 with total page 859 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Encyclopedia of Soil Science provides a comprehensive, alphabetical treatment of basic soil science in a single volume. It constitutes a wide ranging and authorative collection of some 160 academic articles covering the salient aspects of soil physics, chemistry, biology, fertility, technology, genesis, morphology, classification and geomorphology. With increased usage of soil for world food production, building materials, and waste repositories, demand has grown for a better global understanding of soil and its processes. longer articles by leading authorities from around the world are supplemented by some 430 definitions of common terms in soil sciences.

Download or read book State of the Art Report on Global and Regional Soil Information written by Christian Omuto and published by Food & Agriculture Organization of the UN (FAO). This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reliable and up-to-date soil information is fundamental to guide policies and decisions in the light of challenges facing food security, climate change adaptation and mitigation, further provision of ecosystem services and sustainable intensification of agriculture. This report reviews the present availability of soil information from legacy maps and reports, and from ongoing global Digital Soil Mapping efforts. It examines soil maps and soil profile databases at the global and national level, global datasets, regional and (inter)-continental soil information products, and the continental soil atlas. It also looks at the evolution of methods and tools for soil mapping, and reviews the requirements of soil information users through survey assessment. Currently, the soil science community is limited in its capacity to provide accurate and updated information to different soil users. This report concludes that there is an urgent need for traditional soil survey/mapping and DSM communities to join forces to fill this gap and meet users' expectations for soil information.

Download or read book The Soils of Italy written by Edoardo A.C. Costantini and published by Springer Science & Business Media. This book was released on 2013-03-29 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Soils of Italy is the first comprehensive book on Italian pedology in seventy years. Taking advantage of the authors’ large experience and of the most up-to-date information and technology, this book treats the main soil types of Italy, their diffusion, their functions, ecological use, and the threats to which they are subjected during centuries of intensive management. It also deals with future scenarios of the relationships between soil science and other disciplines, such as urban development, medicine, economics, sociology, and archaeology. The description of the soils is accompanied by a complete set of data, pictures and maps, including benchmark profiles. Factors of soil formation are also treated, making use of new, unpublished data and elaborations. The book also includes a history of pedological research in Italy, spanning over a century.

Download or read book The Soils of Mexico written by Pavel Krasilnikov and published by Springer Science & Business Media. This book was released on 2013-02-12 with total page 188 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mexico is an extensive country with an extremely complex mosaic of landscapes. The soils of Mexico have still not been completely studied, and there are few publications available on this subject. This book provides a state-of-the-art view on Mexican soils, their geographical distribution, their use and degradation. This is a first attempt to give a systematized characteristic of the soil resources of Mexico. Land resources of the second-biggest economy in Latin America are critical for its sustainable development, and a demand for adequate soil information is high. The information contained within can be used for any soil-related research done in Mexico and in neighboring countries. The book includes detailed characteristics of soils of all the physiographic regions of Mexico with maps, photos and explanatory schemes. The book is based on the experiences of the authors in research and soil survey, as well as on the existent, mainly ‘grey’ literature on Mexican soils. The book is recommended for researchers and university readers, students of all levels and decision-makers, working in the area of soil science, environmental issues, Earth sciences, land management and nature conservation.
