Download or read book Agriculture and the Nitrogen Cycle written by Arvin Mosier and published by Island Press. This book was released on 2013-04-10 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen is an essential element for plant growth and development and a key agricultural input-but in excess it can lead to a host of problems for human and ecological health. Across the globe, distribution of fertilizer nitrogen is very uneven, with some areas subject to nitrogen pollution and others suffering from reduced soil fertility, diminished crop production, and other consequences of inadequate supply. Agriculture and the Nitrogen Cycle provides a global assessment of the role of nitrogen fertilizer in the nitrogen cycle. The focus of the book is regional, emphasizing the need to maintain food and fiber production while minimizing environmental impacts where fertilizer is abundant, and the need to enhance fertilizer utilization in systems where nitrogen is limited. The book is derived from a workshop held by the Scientific Committee on Problems of the Environment (SCOPE) in Kampala, Uganda, that brought together the world's leading scientists to examine and discuss the nitrogen cycle and related problems. It contains an overview chapter that summarizes the group's findings, four chapters on cross-cutting issues, and thirteen background chapters. The book offers a unique synthesis and provides an up-to-date, broad perspective on the issues of nitrogen fertilizer in food production and the interaction of nitrogen and the environment.
Download or read book Nitrogen Management and Ground Water Protection written by Ronald F Follett and published by Elsevier. This book was released on 2012-12-02 with total page 412 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supplying crops with adequate nitrogen is vital to ensuring food supplies. Once nitrogen is added to the soil, it is subject to chemical transformations of the nitrogen-cycle including transformation to nitrate. Excessive amounts of accumulated nitrate may then leach out of the soil and could potentially enter and contaminate drinking water supplies. The purpose of this book is to examine the subject of nitrogen management and ground water protection. The issue of maintaining ground water quality is addressed primarily from an agronomic point of view. Topics covered include: health and economic aspects of nitrate in drinking water; nitrate sources; ground water nitrate in the USA and other developed countries; transport, leaching and accounting for nitrogen; soil, nitrogen, crop and water management; and nitrate in aquifer systems. The book contains a keyword index and is organized into thirteen chapters, each with appropriate references, tables and figures. Chapter authors are among the leading experts on the subject of nitrate and ground water quality. Readers to whom the book is directed include soil scientists and agronomists, agricultural engineers (irrigation and drainage), environmental scientists, agricultural policy makers, and hydrologists.
Download or read book A Framework for Assessing Effects of the Food System written by National Research Council and published by National Academies Press. This book was released on 2015-06-17 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.

Available in PDF, EPUB and Kindle. Book excerpt: This book examines the costs involved in reducing ammonia emissions from agricultural practices as well as the potential benefits for climate change mitigation. It features contributions by experts in agricultural production processes, producers of agricultural equipment and service providers as well as scientists who assess the issue from an European perspective. Coverage examines all agricultural production stages starting from animal feed and housing, including the storage and application of liquid and solid manure and of mineral fertilizer. In addition, the book looks at the relationship between ammonia control and greenhouse gas emissions and details the GAINS (Greenhouse Gas and Air Pollution Interactions and Synergies) model for estimating costs and reducing ammonia emissions from agriculture. Examples and case studies from select European countries, including Italy, Switzerland, Russia, Ireland, and Spain, provide readers with detailed studies of ammonia abatement costs and the effectiveness of implementing control measures under different conditions. This book is the result of an Expert Workshop held under the auspices of the UNECE Convention on Long-range Transboundary Air Pollution (CLRTAP) and organised by the Task Force on Reactive Nitrogen (TFRN). The findings of this workshop have informed the development of documents supporting the revision of the Gothenburg Protocol and provided researchers and practitioners with vital new data. Bringing together a wealth of key information on the costs of ammonia abatement and the climate co-benefits, this monograph provides readers with deep insight into this complex issue.

This book was released on 2019-02-15 with total page 182 pages. Available in PDF, EPUB and Kindle. Book excerpt: This publication examines the risks associated with the release of excessive nitrogen into the environment (climate change, depletion of the ozone layer, air pollution, water pollution, loss of biodiversity, deterioration of soil quality). The report also examines the uncertainty associated with the ability of nitrogen to move from one ecosystem to another and cause "cascading effects". In addition to better management of nitrogen risks at the local level, there is a need to consider the global risks associated with the continued increase in nitrous oxide concentrations and to prevent excess nitrogen in all its forms by developing cost-effective strategies for all its sources. Other than the reduction of nitrogen pollution, this report provides guidance on the use of nitrogen policy instruments and how to ensure coherence with objectives such as food security, energy security and environmental objectives.

Download or read book Soil Specific Farming written by Rattan Lal and published by CRC Press. This book was released on 2015-08-20 with total page 431 pages. Available in PDF, EPUB and Kindle. Book excerpt: Faced with challenges of resource scarcity and environmental degradation, it is important to adopt innovative farming systems that maximize resource efficiency while protecting the environment. Soil-Specific Farming: Precision Agriculture focuses on principles and applications of soil-specific farming, providing information on rapidly evolving agricultural technologies. It addresses assessments of soil variability and application of modern innovations to enhance use efficiency of fertilizers, irrigation, tillage, and pesticides through targeted management of soils and crops. This book provides the technological basis of adopting and promoting precision agriculture (PA) for addressing the issues of resource scarcity, environmental pollution, and climate change. It focuses specifically on PA technologies and discusses historical evolution, soil variability at different scales, soil fertility and nutrient management, water quality, land leveling techniques, and special ecosystems involving small landholders and coastal regions. Highlighting the scale-related issues and concerns of small landholders, the text details the efficient use of resources on the basis of soil/field variability and site-specific conditions. It examines how PA technology can increase productivity, enhance profitability, and minimize environmental degradation. Woven throughout is the theme of sustainable use of resources.
Download or read book Social Innovation and Sustainability Transition written by Geoff Desa and published by Springer Nature. This book was released on 2022-12-11 with total page 383 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book uses a historical and modern lens to reimagine the role that Extension could potentially play in catalyzing reciprocal, co-learning relationships between Land-Grant Universities and their diverse local constituencies. The establishment of statewide extension systems was once seen as a way to ensure that Land-Grant Universities would be accessible and responsive to all of a state’s residents. Extension systems continue to offer a front-door to a major public university in almost every county of the United States, but they tend to be viewed primarily as a way to translate science or distribute information from the university to the public. This books argues for the importance of Extension and shows that we are conceiving of this system too narrowly. Only by retelling the stories of the Extension and getting people to see themselves as part of the story can we imagine a different future in which state universities and land-grant colleges engage more authentically and equitably in two-way relationships with their local constituents.in catalyzing reciprocal, co-learning relationships between Land-Grant Universities and their diverse local constituencies.
