Download or read book Nitrogen in the Marine Environment written by Edward J. Carpenter and published by Elsevier. This book was released on 2013-10-22 with total page 919 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen in the Marine Environment provides information pertinent to the many aspects of the nitrogen cycle. This book presents the advances in ocean productivity research, with emphasis on the role of microbes in nitrogen transformations with excursions to higher trophic levels. Organized into 24 chapters, this book begins with an overview of the abundance and distribution of the various forms of nitrogen in a number of estuaries. This text then provides a comparison of the nitrogen cycling of various ecosystems within the marine environment. Other chapters consider chemical distributions and methodology as an aid to those entering the field. This book discusses as well the enzymology of the initial steps of inorganic nitrogen assimilation. The final chapter deals with the philosophy and application of modeling as an investigative method in basic research on nitrogen dynamics in coastal and open-ocean marine environments. This book is a valuable resource for plant biochemists, microbiologists, aquatic ecologists, and bacteriologists.

Excerpt from book: Since the armistice governmental research on nitrogen fixation has been carried on largely at the Fixed Nitrogen Research Laboratory, originally organized in the Ordnance Department and recently transferred to the Department of Agriculture. G. PRESENT STATUS OF NITROGEN FIXATION. 1. In the United States. In this country there are the two commercial fixation plants, the synthetic-ammonia plant of the Atmospheric Nitrogen Corporation at Syracuse, N. Y., with an annual capacity of 3,000 tons of nitrogen, and the arc-process plant of the American Nitrogen Products Co., near Tacoma, Wash., with an annual capacity of some 300 tons of nitrogen. There are also the two Government fixation plants, now idle and in indefinite stand-by, the tried-out cyanamide plant at Muscle Shoals, Ala., with an annual capacity of 40,000 tons of nitrogen, and the synthetic-ammonia plant at Sheffield, Ala., which, with extensive modification of equipment, should have an annual capacity of 8,000 tons of nitrogen. There is thus an operating capacity of 3,300 tons and an idle capacity of an additional 48,000 tons. On the other hand, the present annual normal demand for inorganic nitrogen in this country over and above the 110,000 tons which can be furnished from the coking of coal is about 105,000 tons. 2. In Foreign Countries. Our progress in nitrogen fixation shows up poorly in comparison with that of many other countries. Germany, besides having a byproduct coke oven capacity somewhat greater than ours, possesses nitrogen fixation plants with an annual capacity of some 400,000 tons of nitrogen, giving her a total domestic supply more than sufficient for her needs, and rendering her entirely independent of imports. Great Britain, too, has about the same by-product coke oven capacity that we have...

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 Symbiotic Nitrogen Fixation written by P. Graham and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the past three decades there has been a large amount of research on biological nitrogen fixation, in part stimulated by increasing world prices of nitrogen-containing fertilizers and environmental concerns. In the last several years, research on plant--microbe interactions, and symbiotic and asymbiotic nitrogen fixation has become truly interdisciplinary in nature, stimulated to some degree by the use of modern genetic techniques. These methodologies have allowed us to make detailed analyses of plant and bacterial genes involved in symbiotic processes and to follow the growth and persistence of the root-nodule bacteria and free-living nitrogen-fixing bacteria in soils. Through the efforts of a large number of researchers we now have a better understanding of the ecology of rhizobia, environmental parameters affecting the infection and nodulation process, the nature of specificity, the biochemistry of host plants and microsymbionts, and chemical signalling between symbiotic partners. This volume gives a summary of current research efforts and knowledge in the field of biological nitrogen fixation. Since the research field is diverse in nature, this book presents a collection of papers in the major research area of physiology and metabolism, genetics, evolution, taxonomy, ecology, and international programs.
Download or read book Carbon and Nitrogen Cycling in European Forest Ecosystems written by Ernst-Detlef Schulze and published by Springer Science & Business Media. This book was released on 2013-12-01 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume quantifies carbon storage in managed forest ecosystems not only in biomass, but also in all soil compartments. It investigates the interaction between the carbon and nitrogen cycles by working along a north-south transect through Europe that starts in northern Sweden, passes through a N-deposition maximum in central Europe and ends in Italy. For the first time biogeochemical processes are linked to biodiversity on a large geographic scale and with special focus on soil organisms. The accompanying CD-ROM provides a complete database of all flux, storage and species observations for modellers.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Fixation of Atmospheric Nitrogen In the following pages I have tried to give an account of the more important processes for the fixation of atmospheric nitrogen, and, more especially, of the theory on which they are based. No attempt has been made even to mention all the proposals regarding methods and apparatus to be found in the patent literature of recent years. The mere enumeration of these would almost occupy the space at my disposal, and in many cases there is no evidence that the proposed methods are in any way workable. I have, therefore, confined myself to those methods which are either in actual operation, or which show promise of assuming technical importance in the near future. I am indebted to the admirable consular report on The Utilisation of Atmospheric Nitrogen, by T. E. Norton, for some valuable information on the purely technical part of the subject. The report also contains an excellent account of the financial and commercial organisation of the various industries connected with the fixation of nitrogen.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Fixation of Atmospheric Nitrogen Available Nitrogen in Commercial Products. The question of the available nitrogen in the various compounds has in a mea sure determined the price of the product, the utilization in the fertilizer art being practically the basis of fixing the price. For a number of years it has been assumed that the selling price of combined nitrogen would be from 12 cents to 13 cents a pound. Thus Chile saltpeter being about 95 per cent pure nitrate of soda would have a theoretical nitrogen content of about per cent or corrected for impurities would have about per cent nitrogen. As the cyanides until recently were not used directly in the fertilizer art and were combined with more expensive products, their price has not been regulated by. Their content of combined nitrogen. The ammonia used in the fertilizer art is almost entirely used as sulphate of ammonia, on account of the cheap ness of the commercial sulphuric acid and the ease of manu facture, and this product would therefore have a theoretical con tent of 21 per cent of nitrogen.

Download or read book Nitrogen Fixation written by and published by BoD – Books on Demand. This book was released on 2020-04-08 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biological nitrogen fixation (BNF), the process by which gaseous N2 is converted into ammonia (NH3) via the enzyme nitrogenase, is crucial for the availability of nitrogen (N) in the terrestrial ecosystem. Some bacteria have the remarkable capacity to fix atmospheric nitrogen to ammonia under ambient conditions, a reaction only mimicked on an industrial scale by a chemical process. This microbiological process converts atmospheric nitrogen into a plant-usable form, thus decreasing the need to use chemical fertilizers in crop production. Chapters in this volume cover different aspects of this fantastic phenomenon, including biofertilizer, organic nitrogen in agricultural systems, nitrogen fertilization for sustainable crop production, and others. This book is designed for researchers, students and general readers.
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.
