Available in PDF, EPUB and Kindle. Book excerpt: Good management practices for carbon and nitrogen are vital to crop productivity and soil sustainability, as well as to the reduction of global greenhouse gases and environmental pollution. Since the 1950's, mathematical models have advanced our understanding of carbon and nitrogen cycling at both the micro- and macro-scales. However, many of the models are scattered in the literature, undergo constant modification, and similar models can have different names. Modeling Carbon and Nitrogen Dynamics for Soil Management clarifies the confusion by presenting a systematic summary of the various models available. It provides information about strengths and weaknesses, level of complexity, easiness of use, and application range of each model. In nineteen chapters, internationally known model developers and users update you on the current status and future direction of carbon and nitrogen modeling. The book's coverage ranges from theoretical comparison of models to application of models to soil management problems, from laboratory applications to field and watershed scale applications, from short-term simulation to long-term prediction, and from DOS-based computer programs to Object-Oriented and Graphical Interface designs. With this broad scope, Modeling Carbon and Nitrogen Dynamics for Soil Management provides the tools to manage complex carbon/nitrogen processes effectively.

Available in PDF, EPUB and Kindle. Book excerpt: Soil Management and Climate Change: Effects on Organic Carbon, Nitrogen Dynamics, and Greenhouse Gas Emissions provides a state of the art overview of recent findings and future research challenges regarding physical, chemical and biological processes controlling soil carbon, nitrogen dynamic and greenhouse gas emissions from soils. This book is for students and academics in soil science and environmental science, land managers, public administrators and legislators, and will increase understanding of organic matter preservation in soil and mitigation of greenhouse gas emissions. Given the central role soil plays on the global carbon (C) and nitrogen (N) cycles and its impact on greenhouse gas emissions, there is an urgent need to increase our common understanding about sources, mechanisms and processes that regulate organic matter mineralization and stabilization, and to identify those management practices and processes which mitigate greenhouse gas emissions, helping increase organic matter stabilization with suitable supplies of available N. Provides the latest findings about soil organic matter stabilization and greenhouse gas emissions Covers the effect of practices and management on soil organic matter stabilization Includes information for readers to select the most suitable management practices to increase soil organic matter stabilization

This book was released on 2012-12-06 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of a symposium held at the College of Charleston, Charleston, South Carolina, USA, 16-20 June 1986. The seed for this symposium arose from a group of physiologists , soU scientists and biochemists that met in Leningrad, USSR in July 1975 at the 12th Botanical Conference in a Session organized by Professor B.B. Vartepetian. This group and others later conspired to contribute to a book entitled Plant Life in Anaerobic Environments (eds. D. D. Hook and R. M. M. Crawford, Ann Arbor Science, 1978). Several contributors to the book suggested in 1983 that a broad-scoped symposium on wetlands would be useful (a) in facilitating communication among the diverse research groups involved in wetlands research (b) in bringing researchers and managers together and (c) in presenting a com prehensive and balanced coverage on the status of ecology ami management of wetlands from a global perspective. With this encouragement, the senior editor organized a Plan ning Committee that encompassed expertise from many disciplines of wetland scientists and managers. This Committee, with input from their colleagues around the world, organized a symposium that addressed almost every aspect of wetland ecology and management.

This book was released on 2008-05-30 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: Carbon and Nitrogen in the Terrestrial Environment is a comprehensive, interdisciplinary description of C and N fluxes between the atmosphere and the terrestrial biosphere; issues related to C and N management in different ecosystems and their implications for the environment and global climate change; and the approaches to mitigate emission of greenhouse gases. Drawing upon the most up-to-date books, journals, bulletins, reports, symposia proceedings and internet sources documenting interrelationships between different aspects of C and N cycling in the terrestrial environment, Carbon and Nitrogen in the Terrestrial Environment fills the gap left by most of the currently available books on C and N cycling. They either deal with a single element of an ecosystem, or are related to one or a few selected aspects like soil organic matter (SOM) and agricultural or forest management, emission of greenhouse gases, global climate change or modeling of SOM dynamics.

Available in PDF, EPUB and Kindle. Book excerpt: The soil system stores more carbon than the atmosphere and biosphere combined. However, until recently, most studies on soil organic matter dynamics had focused on near surface soil organic carbon (C) dynamics with relatively little attention devoted to determining how much C and nitrogen (N) is stored in deep soil layers, and how climate influences deep soil organic C and N dynamics. Hence, our understanding of how climate influences the mechanisms that regulate the magnitude and direction of changes in deep soil organic matter remain incomplete. In my dissertation research, I studied soils that developed under four different climatic regimes along an elevation gradient on the western slopes of the Sierra Nevada in California (site of the Southern Sierra Critical Zone Observatory). Using soil samples that were collected from the surface down to bedrock contact (that extended to more than 10 m below the surface), I determined how climate regulates deep soil organic carbon and nitrogen stocks, chemical composition of organic matter, mean residence times of soil carbon and nitrogen at depth; and conducted statistical analyses to determine how variability of climate along the SSCZO bio-climosequence is related to a range of climatic variables. In the first chapter, I found that up to 78% of soil C is stored below a 0.3-m depth, with up to 29% of total C stored in saprock below 1.5 m. A conservative global scaling of these results illustrates that deep regolith stores over 200 Pg of organic carbon quantifying a previously unrealized organic carbon pool in the Earth system. In the second chapter, I dug deeper into C stabilization mechanisms and how climate impacts distribution of C in free and mineral protected pools of soil C.I discovered that the radiocarbon concentration of C in the topsoil and subsoil free particulate and subsoil mineral associated fractions had a statistically significant relationship with climate. However, the aggregate protected pool of C was not influenced by climate, suggesting that the free particulate and subsoil mineral associated fractions of subsoil C are vulnerable to changes in climate. The third chapter focused on dynamics of soil N in topsoil compared to subsoils and shows that climate imposes important controls on N in topsoil and subsoil free particulate and occluded fractions. The mineral associated N was not found to be sensitive to changes in climate. Overall, my dissertation research demonstrated both indirect and direct mechanisms through which climate can impact soil C and N dynamics from the topsoil to bedrock contact. I presented substantial evidence to refute the long-held assumption that subsoil organic matter does not respond to changes in atmospheric climate.
