Book Synopsis Chemical Aspects of Soil Freezing by : Karen S. Henry
Download or read book Chemical Aspects of Soil Freezing written by Karen S. Henry and published by . This book was released on 1988 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil water chemistry and soil particle characteristics directly and significantly influence the freezing process in soils. The rate of frost heave is influenced because chemicals modify water migration and depress the freezing point in soils. Solutes are concentrated when they are expelled from crystallizing ice, modifying adsorbed film thicknesses, depressing freezing points, creating concentration gradients, altering forces between particles or between ice particles, and modifying the chemical potential of the water. These effects often have counteracting influences on frost heave. Solute expulsion during freezing produces a 'fringe-like' freezing front in saline soils, primarily because of freezing point depression; this may also be true in 'non-saline' soils. Heave can be reduced by adding chemicals to soil to depress the freezing point to modify the soil's structure or hydraulic characteristics. The concentration of solutes in the unfrozen water of the freezing soil can possibly be used for isolating toxic wastes in soil. Ground freezing, Soils, Soil chemistry, Soil freezing. (mjm).

Book Synopsis Material Cycling of Wetland Soils Driven by Freeze-Thaw Effects by : Xiaofei Yu
Download or read book Material Cycling of Wetland Soils Driven by Freeze-Thaw Effects written by Xiaofei Yu and published by Springer Science & Business Media. This book was released on 2012-11-09 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Freezing and thawing of soils is a common phenomenon in the winter-cold zone. The thesis titled “Material Cycling of Wetland Soils Driven by Freeze-Thaw Effects” systematically explores the freeze-thaw effects on the accumulation and release processes of carbon and nitrogen in wetland soils, which is a good step toward the investigation of biogeochemical processes in wetlands in seasonal freeze-thaw areas. It is also developing strategies aimed at global warming effects on the accumulation and release of carbon and nitrogen in wetlands. Dr. Xiaofei Yu works at the Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences, China.

Book Synopsis Progress in Nitrogen Cycling Studies by : O. van Cleemput
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.
