Better Manage Soil C for Improved Soil Quality In the United States, soil has fueled the availability of abundant, safe food, thus underpinning economic growth and development. In the future we need to be more vigilant in managing and renewing this precious resource by replacing the nutrients and life-sustaining matter that we remove for our own needs. Taking these issues into consideration, Soil Carbon Management: Economic, Environmental, and Societal Benefits explores all of the advantages of effective soil carbon (C) management. A Different Way of Examining Soil C Management This unique resource provides a new conceptual framework to develop policies for managing and enhancing soil C and presents new approaches to achieve positive environmental outcomes. In each chapter, the book poses a problem or set of problems and then describes how effective soil C management can help to solve these challenges, listing the multiple benefits that arise from these practices. The book addresses specific problems such as soil erosion and land degradation and evaluates the advantages of soil C sequestration, specifically for policy development purposes. The policies discussed can be tailored to meet regional and local needs and constraints. The book also explains how to achieve an ideal environment by applying beneficial practices for farming and land management. A Plan for the Future Illustrating how to conserve and preserve soil quality for future generations and detailing how to restore the ecological functions of soil, this book will aid in the formulation of future agricultural policies that sustain food and fuel needs and have long-lasting, positive environmental impacts.

Since carbon sequestration in soils reduces the amount of carbon available to the atmosphere, the Kyoto Protocols have heightened interest in soil carbon pools and their effect on carbon fluxes. Assessment Methods for Soil Carbon addresses many of the questions related to the measurement, monitoring, and verification of organic and inorganic carbon in soils. The major topics covered are: carbon pools; soil samplingand preparation, analytical techniques for soil carbon; soil erosion and sedimentation; remote sensing, GIS and modeling; procedures for scaling carbon data from point and local measurements to regional and even national scales; and economic and policy issues.In Assessment Methods for Soil Carbon, leading researchers show that we now have the ability to measure, monitor, and verify changes to soil carbon. The book establishes the need for standardized methods that can be used by anyone, and helps us better understand the link between the pedosphere (soils) and the atmosphere. It also shows the importance of developing links between the economics of carbon sequestration and the amounts sequestered, and highlights the need for scientists and policy makers to interact to ensure that policies fit within the scope of present technologies.

Global Climate Change and Cold Regions Ecosystems provides information on soil processes and the carbon cycle in cold ecoregions as well as the soil carbon pool and its fluxes in the soils of cold ecoregions. Filling a void in this area of soil science, this resource explains soil processes influencing C dynamics under natural and disturbed ecosystems.The soils of the cold region ecosystems serve as a net sink of atmospheric C. However, an increase in global temperature could render them a net source. In the event of global warming, the cold regions ecosystems-arctic, sub-arctic, alpine, Antarctic, boreal forests, and peatlands-will undergo radical changes. Potential environmental change could drastically increase the active soil layer and influence the large C pool found in them.Topics include: soil C pools in different cold ecoregions, the impact of natural and anthropogenic disturbances on the soil C pool, the method of assessment of C and other properties of soils of the cold regions ecosytems while focusing on the fate of C in permafrost soils. Global Climate Change and Cold Regions Ecosystems covers the current and possible future effects of the cold ecoregions soil C pool on the global carbon pool.

Tropical ecosystems - the regions between the tropics of Cancer and Capricorn - play an important role in global processes, economic issues, and political concerns. In their natural state, tropical ecosystems support a large quantity of above- and below-ground biomass, and constitute a major part of the terrestrial carbon pool. Conversion of the natural ecosystem to agriculture and forestry ecosystems disturbs this ecological balance. Global Climate Change and Tropical Ecosystems presents data on carbon pool fluxes from case studies in 12 countries in tropical regions. The chapters cover:Characteristics of tropical ecosystems Soil and biotic carbon pools Impacts of land use and soil management Slash-and-burn practices Crop residue and fertility managementThis volume adds to the understanding of pedospheric processes in tropical ecosystems and how to better use soils as a sink for carbon dioxide and other greenhouse gases. With Global Climate Change and Tropical Ecosystems you will understand the link between soil productivity, environmental quality and the global carbon cycle, not only in these ecologically sensitive regions but worldwide.

Much attention has been given to above ground biomass and its potential as a carbon sink, but in a mature forest ecosystem 40 to 60 percent of the stored carbon is below ground. As increasing numbers of forests are managed in a wide diversity of climates and soils, the importance of forest soils as a potential carbon sink grows.The Potential of U.S. Forest Soils to Sequester Carbon and Mitigate the Greenhouse Effect provides researchers and policy makers with an understanding of soil processes and their relation to carbon dynamics, as well as strategies to monitor and techniques to measure forest soil carbon. It covers the effects of management on soils in a wide range of forest ecosystems together with policy options that are effective and benefit both the forest community and the over all environment. This valuable reference provides forest managers, urban planners, land owners, policy makers, and the general public with guidance that will allow for a holistic approach to land management, environmental quality, and improved forest productivity.

Soil Degradation in the United States: Extent, Severity, and Trends examines the magnitude and severity of soil degradation by different processes in the U.S., including water erosion, wind erosion, C depletion, soil compaction, salt build-up, and soil contamination. In addition, it addresses policy issues with regard to economic and environmental impact, land use change, and global trends. It covers past trends and future projections regarding soil degradation. The book provides a ready reference and data source for soil scientists and researchers, agronomists, environmentalists, land use planners, land managers, and policy makers.

The potential to mitigate greenhouse gas emissions and global climate change is one factor driving agricultural policy development of programs that might pay farmers for practices with a high potential to sequester carbon. With chapters by economists, policy makers, farmers, land managers, energy company representatives, and soil scientists, Agricultural Practices and Policies for Carbon Sequestration in Soil explores a broad range of topics. It examines topics such as the effects of soil tillage and mulch rate, soil monitoring and assessment, soil fertility management, policy options, and the economic issues associated with carbon sequestration.This volume caps a "series" of books from leading researchers on carbon sequestration in soils by integrating the science with the economic and policy issues surrounding it. It provides agricultural scientists, farmers, and policy makers with innovative and environmentally friendly practices for improved land management and crop production. Agricultural Practices and Policies for Carbon Sequestration in Soil helps to identify strategies that can lead to widespread adoption of management practices that will enhance productivity, the soil carbon pool, and the overall environment.

World soils contain about 1500 gigatons of organic carbon. This large carbon reserve can increase atmospheric concentrations of CO2 by soil misuse or mismanagement, or it can reverse the 'greenhouse' effect by judicious land use and proper soil management.Soil Processes and the Carbon Cycle describes soil processes and their effects on the global carbon cycle while relating soil properties to soil quality and potential and actual carbon reserves in the soil. In addition, this book deals with modeling the carbon cycle in soil, and with methods of soil carbon determinations.

This book addresses the importance of soil processes in the global carbon cycle.Agricultural activities considered responsible for an increase in CO2 levels in our atmosphere include: deforestation, biomass burning, tillage and intensive cultivation, and drainage of wetlands.However, agriculture can also be a solution to the problem in which carbon can be removed from the atmosphere and permanently sequestered into the soil. Management of Carbon Sequestration in Soil highlights the importance of world soils as a sink for atmospheric carbon and discusses the impact of tillage, conservation reserve programs (CRP), management of grasslands and woodlands, and other soil and crop management and land use practices that lead to carbon sequestration.
