The Effects of Tree-Tip Microtopography on Soil Genesis, Northern Michigan
Thesis (Ph.D.)--University of Illinois at Urbana-Champaign, 1987.

Soil genesis on relatively young surface mined lands in southern West Virginia
… chemical properties as a function of age on mine soils formed from overburden from the New River formation of the Pennsylvanian system in southern West Virginia. Within each group, we sampled nine separate sites and further categorized each to one of three predominant overburden types as observed …

Soil Genesis and Vegetation Response to Amendments and Microtopography in Two Virginia Coastal Plain Created Wetlands
… issues including low organic carbon (OC), high soil bulk density (BD), lost topsoil, incorrect hydrology, and failure of targeted vegetation establishment. Organic matter (OM) amendments help created wetlands attain these functions quicker, but, their long-term effects are seldom reported. This …

Mine soil genesis and tall fescue nutrient status as a function of overburden type and cultural amendment
Natural soils in the Appalachian coal mining region occur on steep slopes and are often thin, rocky, acidic, and/or infertile. This often makes use of natural topsoil for surface coal mine reclamation impractical. Sandstone (SS) and siltstone (SiS) topsoil substitute materials in mixed and pure …

Soil genesis studies of upland soils formed in transported materials overlying the Virginia Piedmont using trend-surface analyses
Soils overlying residuum on upland divides and interfluves that formed from transported material are common in the Virginia Piedmont. They are thought to occur on the oldest landscapes in the region. A study was initiated in Appomattox County and a small portion of Buckingham County encompassing an …

The Engineering Properties of Glacial Tills in the Taff Valley, South Wales
… an investigation of the glacial and periglacial soils of the Taff Valley.<br/><br/>The study procedures adopted and the techniques used were chosen from a review of the relatively limited literature relevant to the subject.<br/><br/>Detailed engineering geological and geomorphological mapping was …

Long-term changes in forest soils of Maine and Illinois
Soil formation is a complex process that varies with climate, relief, parent material, organisms, and time. Most soil genesis and weathering experiments are short-term and focus on addressing primarily climate, relief, parent material, or organism as a single factor. Long-term soil genesis …

The Effect of Management on Erosion of Civil War Battlefield Earthworks
… War Earthworks while allowing public access. Soil erosion, both natural and human-induced, is a major concern facing the preservation of the earthworks. Currently, the National Park Service is committed to preserving these earthworks for future generations by determining which maintenance …

Alteration of dioctahedral micas in soils
… conducted on four dioctahedral micas found in soil parent material of the Virginia Piedmont. Emphasis was given to the relationship between loss of K (also Na in certain cases), increase in CEC, and expansion characteristics. Boiling treatments with several different solutions were used to …

Analysis of Reconstructed Mine Soils on Reclaimed Coal and Mineral Sands Mined Lands in Virginia
… use potentials are greatly influenced by mine soil properties. I analyzed and classified coal mine soils in SW VA and mineral sands mine soils in SE VA to aid development of appropriate post-mining land use interpretations. For coal mine soils, long-term pedogenesis was assessed in sandstone …
