Book Synopsis Soil, Fertilizer, and Plant Silicon Research in Japan by : Jian Feng Ma
Download or read book Soil, Fertilizer, and Plant Silicon Research in Japan written by Jian Feng Ma and published by Elsevier. This book was released on 2002-08-09 with total page 294 pages. Available in PDF, EPUB and Kindle. Book excerpt: Silicon (Si) plays a significant role in the resistance of plants to multiple stresses including biotic and abiotic stresses. Silicon is also the only element that does not damage plants when accumulated in excess. However, the contribution of Si to plant growth has been largely ignored due to its universal existence in the earth's crust. From numerous intensive studies on Si, initiated in Japan about 80 years ago, Japanese scientists realized that Si was important for the healthy growth of rice and for stability of rice production. In a worldwide first, silicon was recognized as a valuable fertilizer in Japan. The beneficial effects of Si on rice growth in particular, are largely attributable to the characteristics of a silica gel that is accumulated on the epidermal tissues in rice. These effects are expressed most clearly under high-density cultivation systems with heavy applications of nitrogen. Si is therefore recognized now as an ''agronomically essential element'' in Japan.Recently, Si has become globally important because it generates resistance in many plants to diseases and pests, and may contribute to reduced rates of application of pesticides and fungicides. Silicon is also now considered as an environment-friendly element. The achievements of Si research in Japan are introduced in this book, in relation to soils, fertilizers and plant nutrition.

Book Synopsis Anthropogenic Soils in Japan by : Makiko Watanabe
Download or read book Anthropogenic Soils in Japan written by Makiko Watanabe and published by Springer. This book was released on 2018-10-11 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book enhances the discussion of anthropized soils with photographs of soil profiles and provides general information about soils in Japan, using data on their physical and chemical properties. Soils targeted in this book have wide spectra in anthropized influences from lesser effects such as agricultural improvements to drastic changes caused by infrastructure construction. These include soils sealed by technic hard materials, on ski slopes, on river embankments and coastal berms, in historical urban parks, on man-made islands in Tokyo Bay, in reclaimed lands, in greenhouse fields, and those filling in swamplands. These examples supported with data can be a bridge between agriculture and civil engineering to understand how anthropogenic activities influence soils. Because anthropogenic impacts have increased during the past decades along with concentrations of populations into cities, processes in soils must be addressed from the point of view of diverse land-use purposes. The book includes information with new data produced by active researchers from many institutes and universities as it refers to soils altered by human activities and thus is informative to specialists in various disciplines related to soils. It is also valuable to students for viewing soils in cities, infrastructure construction areas, and other affected locations. Evaluation and understanding of soils now has become essential for researchers in a range of fields and for policy makers in agriculture as well as urban planning, civil engineering, and disaster sciences. This work serves as an impetus for launching further study of soils and environments.

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.

Book Synopsis The One-Straw Revolution by : Masanobu Fukuoka
Download or read book The One-Straw Revolution written by Masanobu Fukuoka and published by New York Review of Books. This book was released on 2010-09-08 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Call it “Zen and the Art of Farming” or a “Little Green Book,” Masanobu Fukuoka’s manifesto about farming, eating, and the limits of human knowledge presents a radical challenge to the global systems we rely on for our food. At the same time, it is a spiritual memoir of a man whose innovative system of cultivating the earth reflects a deep faith in the wholeness and balance of the natural world. As Wendell Berry writes in his preface, the book “is valuable to us because it is at once practical and philosophical. It is an inspiring, necessary book about agriculture because it is not just about agriculture.” Trained as a scientist, Fukuoka rejected both modern agribusiness and centuries of agricultural practice, deciding instead that the best forms of cultivation mirror nature’s own laws. Over the next three decades he perfected his so-called “do-nothing” technique: commonsense, sustainable practices that all but eliminate the use of pesticides, fertilizer, tillage, and perhaps most significantly, wasteful effort. Whether you’re a guerrilla gardener or a kitchen gardener, dedicated to slow food or simply looking to live a healthier life, you will find something here—you may even be moved to start a revolution of your own.

Book Synopsis Agricultural Implications of the Fukushima Nuclear Accident (III) by : Tomoko M. Nakanishi
Download or read book Agricultural Implications of the Fukushima Nuclear Accident (III) written by Tomoko M. Nakanishi and published by Springer. This book was released on 2019-01-30 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book presents the findings from on-site research into radioactive cesium contamination in various agricultural systems affected by the Fukushima Daiichi Nuclear Power Plant accident in March 2011. This third volume in the series reports on studies undertaken at contaminated sites such as farmland, forests, and marine and freshwater environments, with a particular focus on livestock, wild plants and mushrooms, crops, and marine products in those environments. It also provides additional data collected in the subsequent years to show how the radioactivity levels in agricultural products and their growing environments have changed with time and the route by which radioactive materials entered agricultural products as well as their movement between different components (e.g., soil, water, and trees) within an environmental system (e.g., forests). The book covers various topics, including radioactivity testing of food products; decontamination trials for rice and livestock production; the state of contamination in, trees, mushrooms, and timber; the dynamics of radioactivity distribution in paddy fields and upland forests; damage incurred by the forestry and fishery industries; and the change in consumers’ attitudes. Chapter 19 introduces a real-time radioisotope imaging system, a pioneering technique to visualize the movement of cesium in soil and in plants. This is the only book to provide systematic data on the actual change of radioactivity, and as such is of great value to all researchers who wish to understand the effect of radioactive fallout on agriculture. In addition, it helps the general public to better understand the issues of radio-contamination in the environment. The project is ongoing; the research groups from the Graduate School of Agricultural and Life Sciences of The University of Tokyo continue their work in the field to further evaluate the long-term effects of the Fukushima accident.
Book Synopsis Chemistry of Soil Organic Matter by : K. Kumada
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.
