Book Synopsis Nitrogen Behavior in Field Soil by : Donald R. Nielsen
Download or read book Nitrogen Behavior in Field Soil written by Donald R. Nielsen and published by Elsevier. This book was released on 2013-10-22 with total page 541 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Environment, Volume 1: Nitrogen Behavior in Field Soil is the first 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. 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.

Book Synopsis Nitrogen Use and Behavior in Crop Production by : L. Fred Welch
Download or read book Nitrogen Use and Behavior in Crop Production written by L. Fred Welch and published by . This book was released on 1979 with total page 62 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most plants absorbmore nitrogen than any other nutrient. Because the amount needed is so large and easily be lost from many soils, nitrogen is usually the most limiting nutrient for plant growth. Although about 79 percent of the atmosphere is nitrogen, only nitrogen-fixingplants such as legumeswith their associated bacteria are able to use this abundant source. The nonleguminous grain crops must receive supplemental nitrogen to produce satisfactory yields. Until the last few decades the supply of available nitrogen in the soil was increased primarily by legumes and manure. These sources should be used when economically feasible, but many important grain-producing areas of the world must now rely on commercial fertilizer nitrogen. For economic reasons researchers and growers have been interested for many years in improving yields from each unit of nitrogen. Recently, however, the efficient use of nitrogen has become an environmental issue as well, because high nitrate concentrations in water may be harmful to humans, especiali infants, and to livestock. If plants absorb more of the addedfertilizer nitrogen, then less is likely to leach from fields into drinking water. Improving nitrogen efficiency has also become crucial in order to conserve dwinling supplies of natural gas, which is used in large quantities to manufacture nitrogenfertilizers.

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 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.

Book Synopsis North American Agroforestry by : Harold E. Gene Garrett
Download or read book North American Agroforestry written by Harold E. Gene Garrett and published by John Wiley & Sons. This book was released on 2022-02-23 with total page 580 pages. Available in PDF, EPUB and Kindle. Book excerpt: North American Agroforestry Explore the many benefits of alternative land-use systems with this incisive resource Humanity has become a victim of its own success. While we’ve managed to meet the needs—to one extent or another—of a large portion of the human population, we’ve often done so by ignoring the health of the natural environment we rely on to sustain our planet. And by deteriorating the quality of our air, water, and land, we’ve put into motion consequences we’ll be dealing with for generations. In the newly revised Third Edition of North American Agroforestry, an expert team of researchers delivers an authoritative and insightful exploration of an alternative land-use system that exploits the positive interactions between trees and crops when they are grown together and bridges the gap between production agriculture and natural resource management. This latest edition includes new material on urban food forests, as well as the air and soil quality benefits of agroforestry, agroforestry’s relevance in the Mexican context, and agroforestry training and education. The book also offers: A thorough introduction to the development of agroforestry as an integrated land use management strategy Comprehensive explorations of agroforestry nomenclature, concepts, and practices, as well as an agroecological foundation for temperate agroforestry Practical discussions of tree-crop interactions in temperate agroforestry, including in systems such as windbreak practices, silvopasture practices, and alley cropping practices In-depth examinations of vegetative environmental buffers for air and water quality benefits, agroforestry for wildlife habitat, agroforestry at the landscape level, and the impact of agroforestry on soil health Perfect for environmental scientists, natural resource professionals and ecologists, North American Agroforestry will also earn a place in the libraries of students and scholars of agricultural sciences interested in the potential benefits of agroforestry.
