Hydropedology is a microcosm for what is happening in Soil Science. Once a staid discipline found in schools of agriculture devoted to increasing crop yield, soil science is transforming itself into an interdisciplinary mulch with great significance not only for food production but also climate change, ecology, preservation of natural resources, forestry, and carbon sequestration. Hydropedology brings together pedology (soil characteristics) with hydrology (movement of water) to understand and achieve the goals now associated with modern soil science. - The first book of its kind in the market - Highly interdisciplinary, involving new thinking and synergistic approaches - Stimulating case studies demonstrate the need for hydropedology in various practical applications - Future directions and new approaches are present to advance this emerging interdisciplinary science
An evolving, living organic/inorganic covering, soil is in dynamic equilibrium with the atmosphere above, the biosphere within, and the geology below. It acts as an anchor for roots, a purveyor of water and nutrients, a residence for a vast community of microorganisms and animals, a sanitizer of the environment, and a source of raw materials for co
Wetlands occur at the interface of upland and aquatic ecosystems, making them unique environments that are vital to ecosystem health. But wetlands are also challenging to assess and understand. Wetland researchers have developed specialized analytical methods and sampling techniques that are now assembled for the first time in one volume. More than 100 experts provide key methods for sampling, quantifying, and characterizing wetlands, including wetland soils, plant communities and processes, nutrients, greenhouse gas fluxes,redox-active elements, toxins, transport processes, wetland water budgets,and more.
Salzburgers and Their Descendants is the original account of the lives and history of a colony of German Protestants who emigrated to Georgia in 1734. Following their arrival, they settled twenty-five miles north of Savannah, in Ebenezer, to create new lives for themselves in a "New World" of religious freedom. The account of this colony is beneficial to the study of Georgia history, as it furthers an understanding of the reasons for emigrating and of the struggles that settlers faced on arrival. The Georgia Open History Library has been made possible in part by a major grant from the National Endowment for the Humanities: Democracy demands wisdom.

Identification of soils as "hydric" is critical to the protection of wetlands under the Clean Water Act (CWA) (Federal Water Pollution Control Act, 2008). According to the "Corps of Engineers Wetlands Delineation Manual" (hereafter referred to as the "Delineation Manual") (Environmental Laboratory, 1987), the presence of a hydric soil is one of three factors that must be met in order for an area to meet the definition of a jurisdictional wetland. The other two are the presence of hydrophytic vegetation and wetland hydrology. The use of the Delineation Manual and Regional Supplements (U.S. Army, COE, 2010) is required for all Federal agencies involved in identification of wetlands that may be jurisdictional, as well as most states that have environmental programs to protect wetlands. The Delineation Manual generally is used on all lands not classified as agricultural lands. The National Food Security Act Manual (USDA, NRCS, 2008) is used on agricultural lands.
"Upholding the high standard of quality set by the previous edition, this two-volume second edition offers a vast array of recent peer-reviewed articles. It showcases research and practices with added sections on ISTIC-World Soil Information, root growth and agricultural management, nitrate leaching management, podzols, paramos soils, water repellant soils, rare earth elements, and more. With hundreds of entries covering tillage, irrigation, erosion control, ground water, and soil degradation, the book offers quick access to all branches of soil science, from mineralology and physics, to soil management, restoration, and global warming."--Publisher's website.
