Download or read book Volcanic Ash Soils written by S. Shoji and published by Elsevier. This book was released on 1994-01-06 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanic eruptions are generally viewed as agents of destruction, yet they provide the parent materials from which some of the most productive soils in the world are formed. The high productivity results from a combination of unique physical, chemical and mineralogical properties. The importance and uniqueness of volcanic ash soils are exemplified by the recent establishment of the Andisol soil order in Soil Taxonomy. This book provides the first comprehensive synthesis of all aspects of volcanic ash soils in a single volume. It contains in-depth coverage of important topics including terminology, morphology, genesis, classification, mineralogy, chemistry, physical properties, productivity and utilization. A wealth of data (37 tables, 81 figures, and Appendix) mainly from the Tohoku University Andisol Data Base is used to illustrate major concepts. Twelve color plates provide a valuable visual-aid and complement the text description of the world-wide distribution for volcanic ash soils.This volume will serve as a valuable reference for soil scientists, plant scientists, ecologists and geochemists interested in biogeochemical processes occurring in soils derived form volcanic ejecta.

Download or read book Sclerotia Grains in Soils written by Makiko Watanabe and published by Springer Nature. This book was released on 2021-02-12 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book introduces what sclerotia grains are, and where and how they exist in soils, by compiling the results obtained from the studies on fungal sclerotia formed by Cenococcum geophilum (Cg) and related species, the visible black small grains persistent for a few thousand to ten thousands of years in forest soils and sediments. The chapters contain the results and discussions on the ecological distribution and regulating factors, characteristics, and function of Cg sclerotia grains, carried out by researchers from soil geography, soil science, soil microbiology, physiology, forestry, analytical chemistry, environmental chemistry, material science, and related disciplines. The anatomy of sclerotia grains in soil was realized in terms of interdisciplinary joint researches, which resulted in deepening understanding of the ecological function of the mesoscale organic component in soils. This book covers the natural history of sclerotia in soils, pedo-sclerotiology.

Download or read book Chemistry of Soil Organic Matter written by K. Kumada and published by Elsevier. This book was released on 1988-01-01 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the large number of papers and books published on soil organic matter (humus), our knowledge of the subject is still very limited, as is our knowledge of humic acid. The author of this book began to study humus at the end of the 1940s and continued until 1984 when he retired from Nagoya University. With the intention of establishing a systematic understanding of soil organic matter, he has compiled facts and a discussion of humus based on his extensive experimental results during the past 40 years.In this book, humic acids are classified into A, B, Rp and P types, based on their optical properties. The elementary composition and other chemical properties of humic acid types are shown to be regularly different from each other. A new method for humus composition analysis applied to various kinds of soils in Japan and several other countries indicates that the diversity of humus compositions of soils is systematically understandable. These findings lead the author to novel theories on the chemical configuration and formation of humic acids and humic substances. Diagenesis of humus under terrestrial conditions is illustrated as to the buried humic horizons of Black soil (Andosol).The book will be useful not only to soil scientists and agronomists but also to geochemists, oceanographers, limnologists, water scientists, biologists and chemists who are dealing with organic matter in terrestrial, aquatic, and sedimentary environments.

Download or read book Radiocesium Dynamics in a Japanese Forest Ecosystem written by Chisato Takenaka and published by Springer Nature. This book was released on 2019-08-21 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book investigates radiocesium movement in all major components of forest ecosystems, e.g. the plants, animals, insects, microorganisms, and soils, during the initial stage of contamination after the incident at Fukushima Daiichi Nuclear Power Plant. Most of the work was conducted at a common research site. More specifically, the book examines the contribution of surface uptake by trees in the dynamics of radiocesium during the initial contamination stage; the movement of radiocesium in the form of small organic fragments that are essential to the radiocesium dynamics in forest ecosystems; and the upward movement of radiocesium due to microorganism activity, which promotes the effective decontamination of the forest floor. Lastly, it explains why spiders could be a valuable indicator of the contamination level in forest ecosystems.

Download or read book Volcanic Activity and Human Ecology written by Payson D. Sheets and published by Elsevier. This book was released on 2013-09-24 with total page 663 pages. Available in PDF, EPUB and Kindle. Book excerpt: Volcanic Activity and Human Ecology deals with dating, chronology, stratigraphy, volcanic activity, and with the impacts of volcanism on animals, plants, human populations, and the environment. Some of the chapters explain how such findings must be weighed against other causes that influence human behavior and survival, such as factors of social customs, climatic change, shifting biogeographic patterns, disease, and the ability to adapt. Each of the chapters that assess the possible human response to volcanism does so by searching for multiple explanations of the archaeological record, avoiding the simple argument that people were dramatically and inevitably overcome by catastrophic geologic events. The book begins with discussions of volcanism as seen by geologists and pedologists. These include s a general overview of volcanoes and volcanism; a review of the production, dispersal, and properties of tephra and of the geologic methods used to study tephra; and the nature of volcanic soils and their economic impact. Subsequent chapters use the geologic and modern records to examine volcanoes as hazards to people. The final series of papers deals with the interrelationships between volcanism and human occupations as seen through the archaeological, paleobotanical, and paleozoological records.
Download or read book Advances in Soil Science written by and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The world population in 1930 was 2 billion. It reached 3 billion in 1960, stands at 4. 6 billion today, and is expected to reach 6 billion by the end of the century. The food and fiber needs of such a rapidly increasing population are enormous. One of the most basic resources, perhaps the most basic of all, for meeting these needs is the soil. There is an urgent need to improve and protect this resource on which the future of mankind directly depends. We must not only learn how to use the soil to furnish our immediate needs, but also ensure that the ability of the soil to sustain food production in the future is unimpaired. This is indeed a mammoth task; a 1977 United Nations survey reported that almost one-fifth of the world's is now being steadily degraded. The diversity of soil makes it cropland necessary for research to be conducted in many locations. There are basic principles, however, that are universal. This, Advances in Soil Sciences, presents clear and concise reviews in all areas of soil science for everyone interested in this basic resource and man's influence on it. The purpose of the series is to provide a forum for leading scientists to analyze and summarize the available scientific information on a subject, assessing its importance and identifying additional research needs. But most importantly, the contributors will develop principles that have practical applications to both developing and developed agricultures.
