Available in PDF, EPUB and Kindle. Book excerpt: This book discusses how to apply the basic principles of pedology to the tropical soils of the Indian subcontinent, with an emphasis on ways to enhance crop productivity. The book showcases the research contributions on pedology, geomorphology, mineralogy, micromorphology and climate change collected from the literature on three major soil types: shrink-swell soils, red ferruginous (RF) soils and the soils that occur in the tropical environments of the Indo-Gangetic Plains (IGP). It also provides insights into several aspects of five pedogenetically important soil orders like Alfisols, Mollisols, Ultisols, Vertisols and Inceptisols found in tropical Indian environments. Documenting the significance of minerals in soils and their overall influence in soil science in terms of pedology, paleopedology, polygenesis and edaphology, it provides a knowledge base that is critical when attempting to bridge the gap between food production and population growth.

This book was released on 2018-09-17 with total page 1002 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interpretation of Micromorphological Features of Soils and Regoliths, Second Edition, provides researchers and students with a tool for interpreting features observed in soil thin sections and through submicroscopic studies. After an introduction and general overview, micromorphological aspects of regoliths (e.g., saprolites, transported materials) are highlighted, followed by a systematic and coherent discussion of the micromorphological expression of various pedogenic processes. The book is written by an international team of experts in the field, using a uniform set of concepts and terminology, making it a valuable interdisciplinary reference work. The following topics are treated: freeze-thaw features, redoximorphic features, calcareous and gypsiferous formations, textural features, spodic and oxic horizons, volcanic materials, organic matter, surface horizons, laterites, surface crusts, salt minerals, biogenic and pedogenic siliceous materials, other authigenic silicates, phosphates, sulphidic and sulphuric materials, and features related to faunal activity. The last chapters address anthropogenic features,archaeological materials and palaeosoils. Updates the first exhaustive publication on interpretation of micromorphological features, with some new chapters and with a larger number of additional references Covers related topics, making micromorphology more attractive and accessible for geomorphologists, archaeologists and quaternary geologists Includes thematic treatment of a range of soil micromorphology fields and broadens its applications Features input from a multi-disciplinary team, ensuring thorough coverage of topics related to soil science, archaeology and geomorphology

This book was released on 2012-12-06 with total page 1057 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil acidity is a major limitation to crop production in many parts of the world. Plant growth inhibition results from a combination of factors, including aluminum, manganese, and hydrogen ion toxicities and deficiencies of essential elements, particularly calcium, magnesium, phosphorus, and molybdenum. Agricultural management practices and acid precipitation have increased acid inputs into the ecosystem and heightened concern about soil acidity problems. While application of lime has proved to be effective in ameliorating surface soil acidity in many areas, significant soil acidity problems still exist. Scientists from Alberta, Canada, recognized the need to provide a forum for researchers from different disciplines to exchange information and ideas on solving problems of plant growth in acid soils. As a result of their efforts, the First International Symposium on Plant-Soil Interactions at Low pH was held at Grande Prairie, Alberta, Canada, in July 1987. In many acid soil areas, liming materials are not readily available, the cost may be prohibitive, or subsoil acidity cannot be corrected by surface application of lime. New management approaches involving both the plant and the soil are needed in these situations. Progress has been made in the selection and breeding of acid-tolerant plants. However, continued progress will be limited by our lack of understanding of the physiological and biochemical basis of differential acidity tolerance among plants.
