Book Synopsis Nitrogen Fertilizer by : Karlene Winslow
Download or read book Nitrogen Fertilizer written by Karlene Winslow and published by Nova Science Publishers. This book was released on 2014-09 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrate and nitrite are two ions largely diffused in the environment because they take part in the nitrogen cycle. Moreover, a great part of atmospheric nitrogen may be oxidized to nitrite and nitrate by microorganisms in plants, soil or water. The more stable form of oxidized nitrogen is nitrate ion, but, through microbial activity, it can be reduced to nitrite ion which is more chemically reactive. Nitrate and its salts are widely used, especially as inorganic fertilizers, and for many other purposes such as oxidizing agents, explosives, in the chemical industry and as food preservatives. This book discusses the agricultural uses, management practices and environmental effects of nitrogen fertilizers.

This book was released on 2001-12-03 with total page 539 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Environment: Sources, Problems, and Management is the first volume to provide a holistic perspective and comprehensive treatment of nitrogen from field, to ecosystem, to treatment of urban and rural drinking water supplies, while also including a historical overview, human health impacts and policy considerations. It provides a worldwide perspective on nitrogen and agriculture. Nitrogen is one of the most critical elements required in agricultural systems for the production of crops for feed, food and fiber. The ever-increasing world population requires increasing use of nitrogen in agriculture to supply human needs for dietary protein. Worldwide demand for nitrogen will increase as a direct response to increasing population. Strategies and perspectives are considered to improve nitrogen-use efficiency. Issues of nitrogen in crop and human nutrition, and transport and transformations along the continuum from farm field to ground water, watersheds, streams, rivers, and coastal marine environments are discussed. Described are aerial transport of nitrogen from livestock and agricultural systems and the potential for deposition and impacts. The current status of nitrogen in the environment in selected terrestrial and coastal environments and crop and forest ecosystems and development of emerging technologies to minimize nitrogen impacts on the environment are addressed. The nitrogen cycle provides a framework for assessing broad scale or even global strategies to improve nitrogen use efficiency. Growing human populations are the driving force that requires increased nitrogen inputs. These increasing inputs into the food-production system directly result in increased livestock and human-excretory nitrogen contribution into the environment. The scope of this book is diverse, covering a range of topics and issues from furthering our understanding of nitrogen in the environment to policy considerations at both farm and national scales.

Book Synopsis Residual Effects of Fall- and Spring-applied Nitrogen Fertilizers on Crop Yields in the Southeastern United States by : Robert W. Pearson
Download or read book Residual Effects of Fall- and Spring-applied Nitrogen Fertilizers on Crop Yields in the Southeastern United States written by Robert W. Pearson and published by . This book was released on 1961 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen fertilizer broadcast in November or December on widely different soils at seven locations in Alabama, Georgia, and Mississippi during 1955-59 was only 49 percent as effective as nitrogen fertilizer applied the following spring when measured by corn yields. In terms of nitrogen recovered, the relative effectiveness was 62 percent. There were no consistent differences among the five nitrogen sources applied in the fall as measured by corn yields, but nitrogen recovery tended to be lower from urea than from the other sources. Considerable residual effects of spring-applied nitrogen were found over a period of 16 months based on both yield and nitrogen uptake by the crops. Average uptakes of 25 and 34 pounds per acre of additional nitrogen were made by the second and third crops, respectively, from the 200-pound original application. This residual nitrogen produced average yield increases of 1,600 pounds of dry forage and 19 bushels of corn per acre. These results emphasize the economic importance of residual nitrogen and the need for soil test procedures for its estimation.
Book Synopsis Clean Coastal Waters by : National Research Council
Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-08-17 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

Book Synopsis Just Enough Nitrogen by : Mark A. Sutton
Download or read book Just Enough Nitrogen written by Mark A. Sutton and published by Springer Nature. This book was released on 2020-11-09 with total page 603 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a unique collection of contributions addressing both the ‘too much’ and ‘too little’ sides of the nitrogen story. Building on analyses started at the 6th International Nitrogen Conference, Kampala, the book explores the idea of ‘just enough nitrogen’: sufficient for sustainable food production, but not so much as to lead to unsustainable pollution and climate problems. The range of nitrogen threats examined, solutions evaluated and science-policy analyses presented here has provided the foundation to agree the ‘Kampala Statement-for-Action on Nitrogen in Africa and Globally,’ as reported in this volume. Humanity today faces unprecedented challenges: How to feed a growing population? How to reduce air pollution, water pollution and climate change? How to handle regional differences in an era of increasing globalization? These questions are at the heart of this edited volume which examines the multi-dimensional nature of the global nitrogen challenge. While humans have massively altered the nitrogen cycle, the consequences have become polarized. Some regions have too much nitrogen, associated with pollution and wasteful use of a valuable resource, while other regions have too little nitrogen, leading to constraints on food production and depletion of soil nutrient stocks. The volume provides a unique collection of contributions addressing both the ‘too much’ and ‘too little’ sides of the nitrogen story. Building on analyses started at the 6th International Nitrogen Conference, Kampala, the book explores the idea of ‘just enough nitrogen’: sufficient for sustainable food production, but not so much as to lead to unsustainable pollution and climate problems. The range of nitrogen threats examined, solutions evaluated and science-policy analyses presented here has provided the foundation to agree the ‘Kampala Statement-for-Action on Nitrogen in Africa and Globally,’ as reported in this volume. Together, the contributions in this book are now informing actions by the International Nitrogen Initiative (INI) in working with the United Nations Environment Programme and others to establish the International Nitrogen Management System (INMS). A key outcome has been to catalyse development of the first Resolution on Sustainable Nitrogen Management, as adopted by the fourth UN Environment Assembly (UNEA/EA.4/Res.14). The work is written for researchers and policy makers and all those interested in seeing how sustainable nitrogen management can contribute to meeting many of the UN Sustainable Development Goals.
Book Synopsis Nitrogen Management and Ground Water Protection by : Ronald F Follett
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.

Book Synopsis Agriculture and the Nitrogen Cycle by : Arvin Mosier
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.
