Available in PDF, EPUB and Kindle. Book excerpt: Profiles in the History of the U.S. Soil Survey offers a broad-ranging collection of essays chronicling the development of the U.S. Soil Survey and its influence on the history of soil survey as a scientific discipline that focuses on mapping, analysis, and description of soils. Appraises the influences of key individuals and institutions on the establishment of federal support for and coordination of U.S. soil surveys. Provides an account of life in the field, detailing experience shared by many soil scientists and survey processionals. Reviews the opening of careers in soil survey to women and African-Americans. Relates aspects of the utility of the soil survey to other federal services, to other fields of research, and to land-use planning. Discusses the future of the U.S. Soil Survey and the new directions both the survey and its uses will take. Soil scientists and other soil survey professionals will find this collection valuable both for the new research it provides and for the memories it preserves of life and work in the field and laboratory. Historians will increasingly turn their attention to this crucial earth science as the intriguing connections between soils, the environment, and human history become more apparent. Teachers, students, and agriculturalists will also appreciate this detailed account of the Soil Survey.

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 Interpreting Soil Test Results written by Pam Hazelton and published by CSIRO PUBLISHING. This book was released on 2016-11-01 with total page 169 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interpreting Soil Test Results is a practical reference enabling soil scientists, environmental scientists, environmental engineers, land holders and others involved in land management to better understand a range of soil test methods and interpret the results of these tests. It also contains a comprehensive description of the soil properties relevant to many environmental and natural land resource issues and investigations. This new edition has an additional chapter on soil organic carbon store estimation and an extension of the chapter on soil contamination. It also includes sampling guidelines for landscape design and a section on trace elements. The book updates and expands sections covering acid sulfate soil, procedures for sampling soils, levels of nutrients present in farm products, soil sodicity, salinity and rainfall erosivity. It includes updated interpretations for phosphorus in soils, soil pH and the cation exchange capacity of soils. Interpreting Soil Test Results is ideal reading for students of soil science and environmental science and environmental engineering; professional soil scientists, environmental scientists, engineers and consultants; and local government agencies and as a reference by solicitors and barristers for land and environment cases.

Download or read book Predictive Soil Mapping with R written by Tomislav Hengl and published by Lulu.com. This book was released on 2018-12-20 with total page 372 pages. Available in PDF, EPUB and Kindle. Book excerpt: Predictive Soil Mapping (PSM) is based on applying statistical and/or machine learning techniques to fit models for the purpose of producing spatial and/or spatiotemporal predictions of soil variables i.e. maps of soil properties and classes at different resolutions. It is a multidisciplinary field combining statistics, data science, soil science, physical geography, remote sensing, geoinformation science and a number of other sciences. Predictive Soil Mapping with R is about understanding the main concepts behind soil mapping, mastering R packages that can be used to produce high quality soil maps, and about optimizing all processes involved so that also the production costs can be reduced. The online version of the book is available at: https: //envirometrix.github.io/PredictiveSoilMapping/ Pull requests and general comments are welcome. These materials are based on technical tutorials initially developed by the ISRIC's Global Soil Information Facilities (GSIF) development team over the period 2014-2017

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.
