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 sampling and 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.

In recent years, viticulture has seen phenomenal growth, particularly in such countries as Australia, New Zealand, the United States, Chile, and South Africa. The surge in production of quality wines in these countries has been built largely on the practice of good enology and investment in high technology in the winery, enabling vintners to produce consistently good, even fine wines. Yet less attention has been paid to the influence of vineyard conditions on wines and their distinctiveness-an influence that is embodied in the French concept of terroir. An essential component of terroir is soil and the interaction between it, local climate, vineyard practices, and grape variety on the quality of grapes and distinctiveness of their flavor. This book considers that component, providing basic information on soil properties and behavior in the context of site selection for new vineyards and on the demands placed on soils for grape growth and production of wines. Soils for Fine Wines will be of interest to professors and upper-level students in enology, viticulture, soils and agronomy as well as wine enthusiasts and professionals in the wine industry.

Use of Microbes for the Alleviation of Soil Stresses, Volume 2: Alleviation of Soil Stress by PGPR and Mycorrhizal Fungi describes the most important details and advances related to the alleviation of soil stresses by PGPR and mycorrhizal fungi. Comprised of eleven chapters, the book reviews the role of arbuscular mycorrhizal fungi in alleviation of salt stress, the role of AM fungi in alleviating drought stress in plants, the impact of biotic and abiotic stressors and the use of mycorrhizal fungi to alleviate compaction stress on plant growth. Written by experts in their respective fields, Use of Microbes for the Alleviation of Soil Stresses, Volume 2: Alleviation of Soil Stress by PGPR and Mycorrhizal Fungi is a comprehensive and valuable resource for researchers and students interested in the field of microbiology and soil stresses.

This book investigates the emergence of organic food and farming as a social movement. Using the tools of political sociology it analyzes and explains how both people and ideas have shaped a movement that from its inception aimed to change global agriculture. Starting from the British Empire in the 1930's, where the first trans-national roots of organic farming took hold, through to the internet-mediated social protests against genetically modified crops at the end of the twentieth century, the author traces the rise to prominence of the movement. As well as providing a historical account, the book explains the movement's on-going role in fostering and organising alternatives to the dominant intensive and industrial forms of agriculture, such as promoting local food produce and animal welfare. By considering it as a trans-national movement from its inception, aiming at cultural and social change, the book highlights what is unique about the organic movement and why it has risen only relatively recently to public attention. The author reports original research findings, focusing largely on the English-speaking world. The work is grounded in academic enquiry and theory, but also provides a narrative through which the movement can be understood by the more general interested reader.
