Book Description
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

Book Description
Global climate change is a natural process that currently appears to be strongly influenced by human activities, which increase atmospheric concentrations of greenhouse gases (GHG). Agriculture contributes about 20% of the world's global radiation forcing from carbon dioxide, methane and nitrous oxide, and produces 50% of the methane and 70% of the nitrous oxide of the human-induced emission. Managing Agricultural Greenhouse Gases synthesizes the wealth of information generated from the GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) effort with contributors from a variety of backgrounds, and reports findings with important international applications. - Frames responses to challenges associated with climate change within the geographical domain of the U.S., while providing a useful model for researchers in the many parts of the world that possess similar ecoregions - Covers not only soil C dynamics but also nitrous oxide and methane flux, filling a void in the existing literature - Educates scientists and technical service providers conducting greenhouse gas research, industry, and regulators in their agricultural research by addressing the issues of GHG emissions and ways to reduce these emissions - Synthesizes the data from top experts in the world into clear recommendations and expectations for improvements in the agricultural management of global warming potential as an aggregate of GHG emissions

Book Description
This book brings together the essential evidence and policy opportunities regarding the global importance of soil carbon for sustaining Earth's life support system for humanity. Covering the science and policy background for this important natural resource, it describes land management options that improve soil carbon status and therefore increase the benefits that humans derive from the environment. Written by renowned global experts, it is the principal output from a SCOPE rapid assessment process project.

Book Description
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

Book Description
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.

Book Description
We monitored greenhouse gas (GHG) emissions from nine vineyards in Lodi, California from April 2011 -- December 2012. These commercial vineyards are replicates of three soil series (Redding, San Joaquin, and Tokay), representing a spectrum of soil texture. We hypothesized that soil characteristics would influence the magnitude of GHG fluxes from precipitation and management events in a Mediterranean climate. During each field visit -- every other week from April to October and monthly from November to March -- we measured carbon dioxide (CO2) and nitrous oxide (N2O) fluxes, soil nitrate (NO3-N) and ammonium (NH4-N), and gravimetric water content (GWC) from vine and inter-vine (alleys) rows. Monthly, we collected soil samples for dissolved organic carbon (DOC) and dissolved organic nitrogen (DON). Additionally, we simulated early spring tillage in March 2012 and first precipitation event of a wet season in September 2012. The first precipitation event in October 2011 resulted in higher N2O fluxes at San Joaquin (35.6 ± 10.7 g N2O-N ha−1, n = 30) and Redding (30.1 ± 10.0 g N2O-N ha−1, n = 30) than Tokay (8.5 ± 3.9 g N2O-N ha−1, n = 30). In mid-May and mid-October 2012, CO2 fluxes were higher at Tokay than San Joaquin or Redding due to seasonal floor management practices, such as cultivation and mowing of cover crops. Management practices effected differences between vine rows and alleys for soil inorganic pools, DOC, and DON from June to October 2012. Precipitation and tillage simulations depicted similar magnitudes of GHG fluxes as monitoring data. Results from this 20-month study suggested differences in N2O fluxes among soils were due to precipitation events, while CO2 fluxes were related to soil disturbance from management practices at the beginning and end of the dry season.
