Download or read book Plant Nitrogen Metabolism written by Jonathan E. Poulton and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is based on papers presented by invited speakers at a symposium entitled "Plant Nitrogen Metabolism" held in conjunction with the 28th Annual Meeting of the Phytochemical Society of North America. The meeting took place on the campus of the University of Iowa at Iowa City during June 26-30, 1988, and attracted 110 participants from 11 countries. The goal of the symposium was to trace the pathway by which nitrogen passes from soil and atmosphere into both primary and secondary nitrogenous metabolites, focusing upon areas which were felt to be most rapidly expanding. From nodulines (nodule specific proteins) and GS/GOGAT mutants to sugar mimics (polyhydroxyalkaloids) and herbicide inhibitors of amino acid metabolism, research in nitrogen metabolism has expanded into areas barely envisioned only a few years ago. Both the nitrogen specialist and the general plant biochemist will be pleased by the range of topics covered here. Following an overview in Chapter 1 of plant nitrogen metabolism, the remaining chapters are loosely organized into three groups. Chapters 2-6 deal primarily with the biochemistry and molecular biology of nitrogen assimilation and transport, Chapters 7-9 with amino acid metabolism, and Chapters 10-12 with secondary metabolites.

Book excerpt: Soil Organic Matter: Its Nature, Its Role in Soil Formation and in Soil Fertility focuses on the contributions of soil organic matter in soil formation and fertility, including weathering, decomposition, and synthesis of humus substances. The publication first elaborates on the main stages in the history of soil humus study and ideas on the composition of soil organic matter and nature of humus substances. Discussions focus on organic substances of individual nature, strictly humus substances in soil organic matter, and humus substances as a complex of high molecular- weight compounds. The text then examines the biochemistry of humus formation, including the role of physical, chemical, and biological factors, origin of humus substances, possible participation of lignin in the formation of humus substances, and the role of oxidizing enzymes in the synthesis of humus substances. The manuscript takes a look at the importance of organic matter in soil formation and soil fertility and the natural factors of humus formation. Topics include the role of organic matter in the weathering and decomposition of soil minerals; role of organic matter in the formation of soil structure; effect of organic matter on the growth and development of plants; and influence of chemical and physicochemical soil properties on humus formation. The publication is a dependable source material for readers interested in the influence of soil organic matter in soil formation and fertility.

Download or read book Nitrogen in the Environment Sources Problems and Management written by R.F. Follett and published by Gulf Professional Publishing. 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.

Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on food security and safety issues in Africa, a continent presently challenged with malnutrition and food insecurity. The continuous increase in the human population of Africa will lead to higher food demands, and climate change has already affected food production in most parts of Africa, resulting in drought, reduced crop yields, and loss of livestock and income. For Africa to be food-secure, safe and nutritious food has to be available, well-distributed, and sufficient to meet people’s food requirements. Contributors to Food Security and Safety: African Perspectives offer solutions to the lack of adequate safe and nutritious food in sub-Saharan Africa, as well as highlight the positive efforts being made to address this lack through a holistic approach. The book discusses the various methods used to enhance food security, such as food fortification, fermentation, genetic modification, and plant breeding for improved yield and resistance to diseases. Authors emphasize the importance of hygiene and food safety in food preparation and preservation, and address how the constraints of climate change could be overcome using smart crops. As a comprehensive reference text, Food Security and Safety: African Perspectives seeks to address challenges specific to the African continent while enhancing the global knowledge base around food security, food safety, and food production in an era of rapid climate change.

Download or read book Agroecosystems of South India written by K. R. Krishna and published by Universal-Publishers. This book was released on 2010 with total page 553 pages. Available in PDF, EPUB and Kindle. Book excerpt: Agroecosystems of South India is a unique treatise that deals with the relevance of natural resources, genetic stocks, fertilizers, and agronomic practices on the productivity of agroecoregions. Within the context of this book, an agroecosystem has been defined as a conglomerate of small cropping zones, which may be mono-cropping expanses or intercrops that occur in various geographic regions of South India. South India abounds with several such agroecosystems that encompass field crops, vegetables, cash crops, plantations, and forest species. However, the main emphasis within this volume is restricted to agroecosystems that include major cereals, legumes, and oil seed crops. There are 10 chapters in this volume. The first, on historical aspects, traces important events related to domestication, introduction of crop species, agricultural implements, development of soil fertility and crop husbandry procedures. An introductory chapter on Agroecosystems delineates various agroecoregions of South India. Their classification based on physiography, soils, and climatic parameters have been dealt with in great detail. Descriptions on natural resources such as soils and their fertility conditions; water resources; climatic conditions including precipitation patterns; and crops and their genotypes are available in chapter 2. The impact of soil fertility and nutrient dynamics on ecosystematic functions and productivity of crops in an agroecosystem forms the central piece of discussions within chapters 3 to 9. Historical background, geographical settings, agroclimate, soils, cropping systems, and productivity trends have been provided for each cropping ecosystem. Recent advances and details on aspects of nutrient dynamics, such as soil nutrients, their availability, physico-chemical transformations, nutrient fluxes, inorganic fertilizer supply, organic manures, crop residue recycling, nutrient carry over and nutrient balances/imbalances form the core of each chapter. The impact of beneficial soil microbes such as Rhizobium, Plant Growth Promoting Rhizobacteria and Arbuscular Mycorrhizas, on nutrient dynamics in soil has also been discussed. More recent developments dealing with modeling nutrients in cropping ecosystems, computer based-simulations, precision farming and site-specific nutrient management have been emphasized. Forecasts on the impact of nutrient dynamics on the future course of agroecosystems are also available. Overall, this book is a scholarly edition that aims at providing an excellent exposition of recent developments within various agroecosystems of South India to a global audience. It highlights the importance of soil fertility and nutrient dynamics within agroecosystems to total food grain and fodder production in South India. It will be a useful book to researchers, professors, and students dealing with agriculture, environmental science, ecology, and plant science.
