DOWNLOAD EBOOKDevelopments in soil classification have accompanied parallel progress in our understanding of the soil system. However the theories behind the classifications and the purposes for which they were created have changed over time. The editors hope that this comprehensive synthesis will help to rally soil scientists around the world to develop an acce

DOWNLOAD EBOOKInterpretation 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

DOWNLOAD EBOOKApplied Soils and Micromorphology in Archaeology provides the most up-to-date information on soil science and its applications in archaeology. Based on more than three decades of investigations and experiments, the volume demonstrates how description protocols and complimentary methods (SEM/EDS, microprobe, micro-FTIR, bulk soil chemistry, micro- and macrofossils) are used in interpretations. It also focuses on key topics, such as palaeosols, cultivation, and occupation surfaces, and introduces a range of current issues, such as site inundation, climate change, settlement morphology, herding, trackways, industrial processes, funerary features, and site transformation. Structured around important case studies, Applied Soils and Micromorphology in Archaeology is thoroughly-illustrated, with color plates and figures, tables and other ancillary materials on its website (www.cambridge.org/9781107011380); chapter appendices can be accessed separately using the web (www.geoarchaeology.info/asma). This new book will serve as an essential volume for all archaeological inquiry about soil.

DOWNLOAD EBOOKSoil degradation has serious global impacts on agronomic, economic, and sociopolitical conditions, however, statistics regarding the degree of these impacts has been largely unreliable. This book aims to standardize the methodology for obtaining reliable and objective data on soil degradation. It will also identify and develop criteria for assessing the severity of soil degradation, providing a realistic scenario of the problem.

DOWNLOAD EBOOKReprinted from Plant and Soil, v.174, nos.1-2 (1995), this volume is devoted to discussions on the role of biological nitrogen fixation (BNF) in agricultural sustainability. Papers presented on BNF in crop forage and tree legumes are augmented with discussion of integrated farming systems involving BNF, soil and N management, and recycling of legume residues. BNF by non-legumes is discussed and attempts to transform cereals into nodulating plants are critically reviewed. Also described are advances in the development of new methodologies to understand symbiotic interactions and to assess N-2 fixation in the field; means of enhancing BNF through plant and soil management; breeding and selection; problems encountered in exploiting BNF under farmers' field conditions; and promising approaches to improve BNF exploitation.

DOWNLOAD EBOOK623435-28a.gifVolume A deals with the dynamics, mobility and transformation of pollutants and nutrients. Soil is a dynamic system in which soil minerals constantly interact with organic matter and microorganisms. Close association among abiotic and biotic entities governs several chemical and biogeochemical processes and affects bioavailability, speciation, toxicity, transformations and transport of xenobiotics and organics in soil environments. This book elaborates critical research and an integrated view on basic aspects of mineral weathering reactions; formation and surface reactivity of soil minerals with respect to nutrients and environmental pollutants; dynamics and transformation of metals, metalloids, and natural and anthropogenic organics; effects of soil colloids on microorganisms and immobilization and activity of enzymes, and metabolic processes, growth and ecology of microbes. It offers up-to-date information on the impact of such a processes on soil development, agricultural production, environmental protection, and ecosystem integrity.
