Download or read book Progress in Nitrogen Cycling Studies written by O. van Cleemput and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 666 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book contains the proceedings of the `8th Nitrogen Workshop' which was held at the University of Ghent, Belgium, from 5 to 8 September 1994. Although nitrogen dynamics in different ecosystems have been studied for several decades, new orientations and other emphases have recently emerged. Previously, nitrogen was considered as an essential element mostly in terms of productivity, but now, more emphasis is attached to environmental consequences. More than 100 contributions in this book tackle recent developments within the fields of nitrogen advice systems, plant response to fertilization, immobilization and mobilization, nitrification, denitrification, leaching, ammonia volatilization and biological nitrogen fixation. A large number of papers is devoted to the formation of gaseous nitrogen compounds, while mineralization-immobilization is another topic of important interest. The book also contains the reports of discussion groups on different aspects of the nitrogen cycle.

Download or read book Integrated Soil and Sediment Research A Basis for Proper Protection written by Herman J.P. Eijsackers and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 810 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing awareness of the irreversible and long-lasting impacts of deterioration and pollution of soils and sediments has had an important influence on environmental policies and research in the last decade. The complexity of the soil and sediment systems and its processes cannot be tackled properly unless scientists from different disciplines work together. With this in mind, a number of multidisciplinary soil research programmes have been started in various European countries. They involve different disciplinary approaches and they aim at different fields of application: agriculture, land use and town and country planning, drinking water supply, nature management. The results that are now appearing need to be integrated in a scientifically sound and useful way. The first European Conference on Integrated Research for Soil and Sediment Protection and Remediation was intended to foster this. The volume contains the edited and selected proceedings of this Conference.
Download or read book Grazed Pastures and Surface Water Quality written by Richard W. McDowell and published by Nova Publishers. This book was released on 2008 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the subject of grasslands used for grazing livestock. Grasslands can be split into improved and unimproved pastures (also a sub-set of rangelands). Land used for livestock industries occupy 70% agricultural land and about 40% of total land and produce 40% of agricultural gross domestic product (FAO, 2005; Steinfeld et al., 2006). Increasing populations and incomes, coupled with a change in diets and urbanisation in the developing world, is enhancing demand for pasture-based products (Devine, 2003; Schmidhuber and Shetty, 2005). For example, milk and meat production is predicted to double to just over 1 billion tonnes of milk and 465 million tonnes of meat by 2050 (Steinfeld et al., 2006). To meet these demands most effort will go into intensification of improved pastures, which translates into high stocking densities supported by large inputs of fertilisers, feed supplements and energy.
Download or read book Scenario Studies for the Rural Environment written by Job F.Th. Schoute and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 709 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rural areas need to fulfil a large variety of functions and to accommodate many activities. The complexity of the problems, limited funds, and the almost irreversible character of some interventions result in a compelling need to evaluate ex ante the effects of alternative solutions for designation of land, for measures to develop infrastructure, and for soil and water management. Scenario studies are undertaken to help manage the complexity, to place bounds on uncertainties, and to create new visions. After an overview of the nature, variety and scope of scenario studies, the book illuminates various European examples and reviews, under the following headings: regional soil and water management; nature development and landscape quality; rural planning and the future of regions.
Download or read book Biosphere Atmosphere Exchange of Pollutants and Trace Substances written by Sjaak Slanina and published by Springer Science & Business Media. This book was released on 2013-03-14 with total page 562 pages. Available in PDF, EPUB and Kindle. Book excerpt: The biosphere is the ultimate sink for air pollutants and is also the source of many precursors for the formation of photo-oxidants. In any analysis of air pollution and for determining source-receptor relationships, reliable emission and pollutant concentrations or depositions must be taken into account, together with their interactions between the atmosphere and the biosphere. This book presents a number of authoritative review articles covering topics which include biosphere-atmosphere exchange of ammonia, nitrogen oxides, ozone and sulfur-containing gases, the biological mechanisms involved in the exchange of trace gases, as well as generalizations of deposition over Europe.
Download or read book Carbon Sequestration in Agricultural Soils written by Alessandro Piccolo and published by Springer Science & Business Media. This book was released on 2012-01-11 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compilation of techniques, methodologies and scientific data arises from a four-year Italian research project, which took place at university research stations in Turin, Piacenza, Naples and Potenza. Soil Organic Matter (SOM) represents an active and essential pool of the total organic carbon on the planet. Consequently, even small changes in this SOM carbon pool may have a significant impact on the concentration of atmospheric CO2. Recent new understanding of the chemical nature of SOM indicates that innovative and sustainable technologies may be applied to sequester carbon in agricultural soils. Overall results of the project have been applied to develop an innovative model for the prediction and description, both quantitatively and qualitatively, of carbon sequestration in agricultural soils. This book provides experts in different areas of soil science with a complete picture of the effects of new soil management methods and their potentials for practical application in farm management.
Download or read book Biomass for Energy Environment Agriculture and Industry written by P. Chartier and published by Newnes. This book was released on 2013-05-30 with total page 941 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interest in the use of biomass for non-food applications has grown strongly in recent years, mainly as a consequence of its potential as a prime renewable energy resource. Renewable energies rank highly among the options that will contribute to the prevention of climate change and to security of energy supply in the future. Furthermore, exploiting biomass is very attractive as a way of dealing with two sensitive issues facing the majority of westernEuropean countries today; the extent of unemployment and the setting aside of farm lands to limit excess agricultural production.The 8th European Conference for Energy, Environment, Agriculture and Industry, held in Vienna, October 1994 was larger that any of its predecessors, with over 300 refereed contributions from 20 countries worldwide and over 520 participants. It was arguably the most significant event to date in this field, providing the opportunity for an international exchange of information on the recent progress in developing and implementing renewable biomass based non-food technologies. Published in 3 volumes, the proceedings of this conference therefore contain the most complete overview of the present state-of-the-art. Subjects covered include: biomass resource base, electricity and heat generation, transportation fuels, chemicals from biomass, products from bio- and thermochemical conversion technologies, economics, environmental aspects and opportunities for implementation worldwide, in particular in developing countries.Apart from the numerous contributions on the most recent results in research, development and implementation, the publication also contains authoritative reviews on most of the above-mentioned areas from leading experts in each field. In addition to this, it contains a list of key issues for developing a successful strategy leading to a rapid implementation in Europe and abroad.As a result it is indispensable for anyone working in this area, whether in research, demonstration or in policy development.
Download or read book Production Practices and Quality Assessment of Food Crops written by Ramdane Dris and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 282 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants require nutrients in order to grow, develop and complete their life cycle. Mineral fertilizers, and hence the fertilizer industry, constitute one of the most imp- tant keys to the world food supplies. There is growing concern about the safety and quality of food. Carbon, hydrogen and oxygen, which, together with nitrogen, form the structural matter in plants, are freely available from air and water. Nitrogen, phosphorus and potassium, on the other hand, may not be present in quantities or forms sufficient to support plant growth. In this case, the absence of these nut- ents constitutes a limiting factor. The supply of nutrients to the plants should be balanced in order to maximise the efficiency of the individual nutrients so that these meet the needs of the particular crop and soil type. For example, it should be noted that EU-wide regulations are not designed to govern the specific details of mineral fertilizer use. Although plants receive a natural supply of nitrogen, phosphorus and potassium from organic matter and soil minerals, this is not usually sufficient to satisfy the demands of crop plants. The supply of nutrients must therefore be supplemented with fertilizers, both to meet the requirements of crops during periods of plant growth and to replenish soil reserves after the crop has been harvested. Pesticides are important in modern farming and will remain indispensable for the foreseeable future.

Download or read book Gaseous Nitrogen Emissions from Grasslands written by S. C. Jarvis and published by Oxford University Press, USA. This book was released on 1997 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book examines the impact of gaseous nitrogen emissions from grasslands on atmospheric chemistry, acid rain, critical loads for ecosystems, climate change and ozone levels. The various stages of grassland production provide numerous opportunities for the escape of these environmentally active gases. These stages are examined and methods for controlling the emissions are explored. The interactions of the processes involved in the generation of these gases with other components of the overall nitrogen cycle are important and the chapters in this book look at these in terms of basic processes through to larger scale systems. The book brings together the leading workers in this area and provides an up-to-date account of the research along with implications for practice in this environmentally sensitive field. It is important reading for all grassland scientists, those involved in research into livestock production using grass and rangelands along with advisors to the farming community. It is also valuable for all those, such as ecologists and conservationists, concerned with pollution and the environment.
