Soils and Geomorphology, now in its third edition, remains popular among soil scientists, geomorphologists, geologists, geographers, and archaeologists. While retaining the useful "factors of soil formation format," it has been extensively revised, incorporating a considerable amount of new research and offering a greater number of topics and examples -- particularly in the chapters "Weathering and Soil Development with Time" and "Topography: Soil Relations with Time in Different Climatic Settings." Greater emphasis is placed on the role of dust in pedogenesis, and new data are included on tropical soil development, global soil-loess relations, neotectonics, and reduction processes. The text discusses field applications such as the use of soils in recognizing climate change, estimating the age of geological deposits, and dealing with environmental problems such as acid rain. New "how-to" appendices on soil descriptions and calculating the profile development index are also included. Soils and Geomorphology is an ideal text for advanced undergraduate and graduate students in courses on pedology, soil science, Quaternary geology, archeology, and sedimentary petrology.

The incredible "glowing" history of the "Devil's element "phosphorus Discovered by alchemists, prescribed by apothecaries, exploited by ninth-century industrialists, and abused by twentieth-century combatants, the chemical element phosphorus has fascinated us for more than three centuries. It may even be the cause of will-o'-the wisps and spontaneous human combustion! Now John Emsley has written an enthralling account of this eerily luminescent element. Shining with wonderful nuggets-from murders-by-phosphorus to a match factory strike; from the firebombing of Hamburg to the deadly compounds derived from phosphorus today-The 13th Element weaves together a rich tableau of brilliant and oddball characters, social upheavals, and bizarre events.

“Principles of Soil Management and Conservation” comprehensively reviews the state-of-knowledge on soil erosion and management. It discusses in detail soil conservation topics in relation to soil productivity, environment quality, and agronomic production. It addresses the implications of soil erosion with emphasis on global hotspots and synthesizes available from developed and developing countries. It also critically reviews information on no-till management, organic farming, crop residue management for industrial uses, conservation buffers (e.g., grass buffers, agroforestry systems), and the problem of hypoxia in the Gulf of Mexico and in other regions. This book uniquely addresses the global issues including carbon sequestration, net emissions of CO2, and erosion as a sink or source of C under different scenarios of soil management. It also deliberates the implications of the projected global warming on soil erosion and vice versa. The concern about global food security in relation to soil erosion and strategies for confronting the remaining problems in soil management and conservation are specifically addressed. This volume is suitable for both undergraduate and graduate students interested in understanding the principles of soil conservation and management. The book is also useful for practitioners, extension agents, soil conservationists, and policymakers as an important reference material.

Recognition of the importance of soil organic matter (SOM) in soil health and quality is a major part of fostering a holistic, preventive approach to agricultural management. Students in agronomy, horticulture, and soil science need a textbook that emphasizes strategies for using SOM management in the prevention of chemical, biological, and physical problems. Soil Organic Matter in Sustainable Agriculture gathers key scientific reviews concerning issues that are critical for successful SOM management. This textbook contains evaluations of the types of organic soil constituents—organisms, fresh residues, and well-decomposed substances. It explores the beneficial effects of organic matter on soil and the various practices that enhance SOM. Chapters include an examination of the results of crop management practices on soil organisms, organic matter gains and losses, the significance of various SOM fractions, and the contributions of fungi and earthworms to soil quality and crop growth. Emphasizing the prevention of imbalances that lead to soil and crop problems, the text also explores the development of soils suppressive to plant diseases and pests, and relates SOM management to the supply of nutrients to crops. This book provides the essential scientific background and poses the challenging questions that students need to better understand SOM and develop improved soil and crop management systems.

Forest soil characteristics are not only unique but their interpretation also differs from cropland soils. Just as there are diverse forest types, there are many soil variants that need different management. Today, forest plantations are being intensively managed for profitable timber, pulpwood and energy production. Site selection, species selection, site productivity evaluation, silvicultural treatments, and soil amendments need crucial soil information. This book provides a comprehensive overview of the physical, chemical and biological properties of forest soils and their implications on forest vegetation. Topics discussed include: major forest types of the world and their associated soils; forest biomass and nutrient dynamics; organic matter turnover and nutrient recycling; forest soil disturbance; forest soil and climate change; and forest soil management and silvicultural treatments.

This book serves as an up-to-date introduction, as well as overview to modern trace fossil research and covers nearly all of the essential aspects of modern ichnology. Divided into three section, Trace Fossils covers the historical background and concepts of ichnology, on-going research problems, and indications about the possible future growth of the discipline and potential connections to other fields. This work is intended for a broad audience of geological and biological scientists. Workers new to the field could get a sense of the main concepts of ichnology and a clear idea of how trace fossil research is conducted. Scientists in related disciplines could find potential uses for trace fossils in their fields. And, established workers could use the book to check on the progress of their particular brand of ichnology. By design, there is something here for novice and veteran, insider and outsider, and for the biologically-oriented workers and for the sedimentary geologists. * Presents a review of the state of ichnology at the beginning of the 21st Century * Summarizes the basic concepts and methods of modern trace fossil research * Discusses crucial background information about the history of trace fossil research, the main concepts of ichnology, examples of current problems and future directions, and the potential connections to other disciplines within both biology and geology

Biochar for Environmental Management

Biochar is the carbon-rich product which occurs when biomass (such as wood, manure or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its persistence in soil and nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with potentially major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process. The first edition of this book, published in 2009, was the definitive work reviewing the expanding research literature on this topic. Since then, the rate of research activity has increased at least ten-fold, and biochar products are now commercially available as soil amendments. This second edition includes not only substantially updated chapters, but also additional chapters: on environmental risk assessment; on new uses of biochar in composting and potting mixes; a new and controversial field of studying the effects of biochar on soil carbon cycles; on traditional use with very recent discoveries that biochar was used not only in the Amazon but also in Africa and Asia; on changes in water availability and soil water dynamics; and on sustainability and certification. The book therefore continues to represent the most comprehensive compilation of current knowledge on all aspects of biochar.
