Agriculture and the Nitrogen Cycle: Assessing the Impacts of Fertilizer Use on Food Production and the Environmentby Arvin R. Mosier and J. Keith Syers and John R. Freney
Synopses & Reviews
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.<BR> 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. <BR> 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.<BR>
Book News Annotation:
The presence of nitrogen in soil is a delicate matter. Too little impedes production of food, feed, and fiber, but too much creates pollution. Distribution of nitrogen is uneven across the globe, creating hunger and want in some places and environmental disasters in others. In this collection of 19 papers derived from a Scientific Committee on Problems of the Environment workshop in January 2004, contributors examine nitrogen efficiency and its impact. Their topics include an overview of nitrogen fertilizer as an essential part of agricultural production; crosscutting issues such as management, technology, health, and social response; low-input systems such as an ecosystem-based or regional approaches; high-input systems such as those using advanced technology; interactions such as nitrogen efficiency as it relates to other nutrients, and current nitrogen inputs to world regions; and the challenges of sustaining production.
