Structure and Organic Matter Storage in Agricultural Soils
Soils comprise the largest pool of terrestrial carbon and therefore are an important component of carbon storage in the biosphere-atmosphere system. Structure and Organic Matter Storage in Agricultural Soils explores the mechanisms and processes involved in the storage and sequestration of carbon in soils. Focusing on agricultural soils - from tropical to semi-arid types - this new book provides an in-depth look at structure, aggregation, and organic matter retention in world soils. The first two sections of the book introduce readers to the basic issues and scientific concepts, including soil structure, underlying mechanisms and processes, and the importance of agroecosystems as carbon regu...
Soil Processes and the Carbon Cycle
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.
Methods for Assessment of Soil Degradation
Soil degradation has serious global impacts on agronomic, economic, and sociopolitical conditions, however, statistics regarding the degree of these impacts has been largely unreliable. This book aims to standardize the methodology for obtaining reliable and objective data on soil degradation. It will also identify and develop criteria for assessing the severity of soil degradation, providing a realistic scenario of the problem.
Soil and Drought
Drought, a serious global issue, is being aggravated by climate change. Both pedological and agronomic droughts are major risk factors with adverse effects on agronomic productivity, food and nutritional security, and human wellbeing. This volume in the Advances in Soil Sciences series provides research information regarding case studies from diverse agro-ecoregions around the world and lists examples of effective management of drought at farm, state, national, regional, and global scales. Features: Considers processes, factors, and causes of pedological/agronomic droughts. Discusses effects of global warming on soil drought and describes management options to enhance drought resilience of a...
The Strong, Silent Type
Many of the stars of silent westerns were young horse wranglers who left the open fields to make extra money bulldogging steers and chasing Indians around arenas in traveling Wild West shows. They made their way to Hollywood when the popularity of the Wild West shows began to decline, found work acting in action-packed silent westerns, and became idols for early moviegoers everywhere. More than 100 of those cowboys who starred in silent westerns between 1903 and 1930 are highlighted in this work. Among those included are Art Acord, Broncho Billy Anderson, Harry Carey, Fred Cody, Bob Custer, Jack Daugherty, William Desmond, William Duncan, Dustin Farnum, William Farnum, Hoot Gibson, Neal Hart, William S. Hart, Jack Holt, Jack Hoxie, Buck Jones, J. Warren Kerrigan, George Larkin, Leo Maloney, Ken Maynard, Tim McCoy, Tom Mix, Pete Morrison, Jack Mower, Jack Perrin, William Russell, Bob Steele, Fred Thompson, Tom Tyler, and Wally Wales, to name just a few. Biographical information and a complete filmography are provided for each actor. Richly illustrated with more than 300 movie stills.
Soil Management and Greenhouse Effect
Soil Management and Greenhouse Effect focuses on proper management of soils and its effects on global change, specifically, the greenhouse effect. It contains up-to-date information on a broad range of important soil management topics, emphasizing the critical role of soil for carbon storage. Sequestration and emission of carbon and other gases are examined in various ecosystems, in both natural and managed environments, to provide a comprehensive overview. This useful reference includes chapters that address policy issues, as well as research and development priorities. The material in this volume is valuable not only to soil scientists but to the entire environmental science community.
