Download or read book Soil Plant Nitrogen Relationships written by Donald R. Nielsen and published by Elsevier. This book was released on 2013-09-03 with total page 543 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Environment, Volume 2: Soil-Plant-Nitrogen Relationships is the second of a two-volume treatise based on manuscripts presented at the international conference on ""Nitrogen in the Environment,"" held at the University of California Conference Center, Lake Arrowhead, in February, 1977. All original manuscripts were revised in accordance with discussions at the conference. The chapters published in these volumes are those revised manuscripts, with provisions in each chapter to preserve the major suggestions for their improvement. These two volumes—Nitrogen Behavior in Field Soil and Soil-Plant-Nitrogen Relationships—should be of value in bringing into perspective current knowledge on selected aspects of nitrogen in the environment. The book contains 22 chapters and opens with a study on the factors influencing nitrate acquisition by plants; assimilation and fate of reduced nitrogen. Separate chapters follow on topics such as absorption and utilization of ammonium nitrogen by plants; potential nitrate levels in edible plant parts; control of biological nitrogen fixation; and methods for analysis of denitrification in soils.

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 320 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.

These two volumes—Nitrogen Behavior in Field Soil and Soil-Plant-Nitrogen Relationships—should be of value in bringing into perspective current knowledge on selected aspects of nitrogen in the environment. This book contains 26 chapters and begins with a paper on field trials with isotopically labeled nitrogen fertilizer. Separate chapters follow on topics such as computer simulation modeling for nitrogen in irrigated croplands; spatial variability of nitrogen in soils; application of gaseous-diffusion theory to measure denitrification; and measurement and prediction of anaerobiosis in soils.

Download or read book Nitrogen Economy in Tropical Soils written by N. Ahmad and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen Economy in Tropical Soils presents an authoritative and comprehensive state-of-the-art review on soil/plant nitrogen inter-relationships, with special reference to tropical soils and crops in aerobic and anaerobic environments. Use of isotopically labelled nitrogen in experimentation, especially in tropical environments, and recently developed analytical techniques for soil and plant materials are presented. An important aspect is the emphasis placed on the impact of the tropical environment on nitrogen transformations in the soil environment. This book should be an excellent source of information for senior undergraduate and graduate students with interest in soil/plant nitrogen inter-relationships, and for all levels of research workers in these fields.
Download or read book Nitrogen Fixation in Agriculture Forestry Ecology and the Environment written by Dietrich Werner and published by Springer Science & Business Media. This book was released on 2006-01-20 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainability has a major part to play in the global challenge of continued development of regions, countries, and continents all around the World and biological nitrogen fixation has a key role in this process. This volume begins with chapters specifically addressing crops of major global importance, such as soybeans, rice, and sugar cane. It continues with a second important focus, agroforestry, and describes the use and promise of both legume trees with their rhizobial symbionts and other nitrogen-fixing trees with their actinorhizal colonization. An over-arching theme of all chapters is the interaction of the plants and trees with microbes and this theme allows other aspects of soil microbiology, such as interactions with arbuscular mycorrhizal fungi and the impact of soil-stress factors on biological nitrogen fixation, to be addressed. Furthermore, a link to basic science occurs through the inclusion of chapters describing the biogeochemically important nitrogen cycle and its key relationships among nitrogen fixation, nitrification, and denitrification. The volume then provides an up-to-date view of the production of microbial inocula, especially those for legume crops.

Download or read book Ecological Aspects of Nitrogen Metabolism in Plants written by Joe C. Polacco and published by John Wiley & Sons. This book was released on 2011-01-20 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Aspects of Nitrogen Acquisition covers how plants compete for nitrogen in complex ecological communities and the associations plants recruit with other organisms, ranging from soil microbes to arthropods. The book is divided into four sections, each addressing an important set of relationships of plants with the environment and how this impacts the plant’s ability to compete successfully for nitrogen, often the most growth-limiting nutrient. Ecological Aspects of Nitrogen Acquisition provides thorough coverage of this important topic, and is a vitally important resource for plant scientists, agronomists, and ecologists.

Download or read book Soil Plant Relationships written by D.W. Jeffrey and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 226 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil-plant relationships once had a limited meaning. To the student of agriculture it meant creating optimum conditions for plant growth. To the ecologist it meant explaining some plant community distribu tion patterns by correlation with soil type or conditions. This dual view has been greatly expanded at an academic level by the discovery of the ecosystem as a practical working unit. A flood of concepts and information subsequently emerged from the International Biological Programme. At a totally different level of resolution, it is appreciated that certain soil-based ecological problems have a molecular basis, and must be addressed by physiological or biochemical approaches. From ecosystem to molecule we have powerful new tools to increase the flow of ecological data and process it for interpretation. Society is now experiencing a series of adverse global phenomena which demand an appreciation of soil-plant relationships. These include desertification leading to famine, soil degradation accom panying forest destruction, acidification of watersheds and the spasmodic dispersal of radionuclides and other pollutants. It is public policy, not merely to identify problems, but to seek strategies for minimising their ill effects. This book is written as a guide to soil-plant relationships, cen trally oriented towards ecology, but of interest to students of geo graphy and agriculture. For ecology students it will bring together subfields such as microbiology, plant physiology, systematics and pro vide interfaces with animal biology, meteorology and soil science.
