Download or read book Environmental Impacts of Pasture based Farming written by Richard W. McDowell and published by CABI. This book was released on 2008 with total page 297 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing on the different types of grassland farming and their impact on the environment, Environmental Impacts of Pasture-based Farming takes a broad and interdisciplinary view of the subject. The text is organized into two sections, the first addressing issues facing environmental quality, namely soil, water and air quality and socioeconomic impacts. The second section offers commentary on how the different pastoral sectors influence environmental issues. With highly tuned farm productive systems comes the risk of environmental impacts, and the purpose of this text is to highlight the areas with which these risks are associated and how best to mitigate them. While drawing attention to potential problems, chapter authors always remain conscious of the socio-economic needs of land users and the increasing world population and keep in mind that intense mitigation may be too restrictive on the farming system. This book takes an unbiased approach to improving management of grazed land and incorporates research from environmental science, agriculture, soil science and ecology.

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 Plant induced soil changes Processes and feedbacks written by N. van Breemen and published by Springer Science & Business Media. This book was released on 1998-08-31 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book by soil scientists and ecologists reviews how and why plants influence soils. Topics include effects on mineral weathering, soil structure, and soil organic matter and nutrient dynamics, case studies of soil-plant interactions in specific biomes and of secondary chemicals influencing nutrient cycling, the rhizosphere, and potential evolutionary consequences of plant-induced soil changes. This is the first volume that specifically highlights the effects of plants on soils and their feedbacks to plants. By contrast, other texts on soil-plant relationships emphasize effects of soil fertility on plants, following the strongly agronomic character of most research in this area. The aspects discussed in this volume are crucial for understanding terrestrial ecosystems, biogeochemistry and soil genesis. The book is directed to terrestrial ecologists, foresters, soil scientists, environmental scientists and biogeochemists, and to students following specialist courses in these fields.

Download or read book Soil Emission of Nitrous Oxide and its Mitigation written by David Ussiri and published by Springer Science & Business Media. This book was released on 2012-11-13 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrous oxide gas is a long-lived relatively active greenhouse gas (GHG) with an atmospheric lifetime of approximately 120 years, and heat trapping effects about 310 times more powerful than carbon dioxide per molecule basis. It contributes about 6% of observed global warming. Nitrous oxide is not only a potent GHG, but it also plays a significant role in the depletion of stratospheric ozone. This book describes the anthropogenic sources of N2O with major emphasis on agricultural activities. It summarizes an overview of global cycling of N and the role of nitrous oxide on global warming and ozone depletion, and then focus on major source, soil borne nitrous oxide emissions. The spatial-temporal variation of soil nitrous oxide fluxes and underlying biogeochemical processes are described, as well as approaches to quantify fluxes of N2O from soils. Mitigation strategies to reduce the emissions, especially from agricultural soils, and fertilizer nitrogen sources are described in detail in the latter part of the book.
