Temporal Dynamics of Groundwater Flow Direction in a Glaciated, Headwater Catchment
… - 6.9 m depth within glacial sediments of the C horizon. I conducted 47 slug tests across the well network to determine hydraulic properties of the aquifer materials surrounding each well. In addition, our team conducted a large-scale auger investigation mapping soil horizon depths and …

The Evolution of the Profile Paradigm in the History of Pedology and Quaternary Geology: Concepts and Applications
… geologists. The PWP subsolum contains a C horizon concept of more precisely defined scope than that traditionally used in pedology. In the traditional sense the interval between the solum and bedrock is designated as the C, whether pedogenically modified or not. In the PWP, the C horizon is …

Growth of juvenile lodgepole pine in relation to soil and slope
… position and soil samples collected from each horizon. A mechanical analysis of the soil was conducted, and soil moisture capacities for each horizon were determined. A total of ten environmental variables were measured and of this number six variables were found to be highly correlated to the …

Long-term changes in forest soils of Maine and Illinois
… Soils at the study site have thick organic horizons and well developed E horizons. Sixty soil-bags were constructed in 1992 using C horizon material from a large soil pit in the plot, and placed directly beneath the Oa horizon in groups of five at 12 locations (sampling was planned to occur …

Factors Influencing Biotite Weathering
… acids, simulated rainfall rates, surface horizons, and temperature on the weathering and cation release of biotite. A field investigation was also conducted on the clay mineral fraction of soils in Grayson County, VA formed above biotite granite. Selected acid leachates did show a greater …

Stratigraphy, magnetic susceptibility, and mineralogy of loess-paleosol sequences in southwestern Illinois and eastern Missouri
… have been delineated within oxidized, C horizon Peoria and Loveland Silts along the Illinois and Mississippi Valleys. Lower Peoria and lower Loveland Silts (MS = 55-80 $\times\ 10\sp{-5}$ SI) and Roxana Silt (MS = 60-90 $\times\ 10\sp{-5}$) have high MS probably reflecting greater …

The genesis and morphology of three southwest Virginia soils which were developed from material weathered from limestone
… Total chemical analyses of the various horizons of the soil profiles showed that the soil forming processes of the three soils studied were podzolic is nature. The parent materials or C horizons of all the soil profiles studied were clays. Hagerstown, which contained approximately 38 …

Reaktivation and stabilization phases of eolian deposits under climatic and anthropogenic influences in the Rolling Plains of Texas, U.S.A.
… soils were eroded, in parts, down to the C-horizon in some of these areas. More mature sand were dated with the radiocarbon method and identified having formed during the Altithermal warming period. This study identifies major eolian anthropogenic and climatic reactivation and stabilisation …

Denitrification potentials in soils underlying a riparian forest and an agricultural field in the coastal plain of Virginia
… water table in the forest was located in the A horizon as compared to the water table in the field which was located in the C horizon. Results demonstrated that denitrification was an active mechanism that affected nitrate reduction in shallow groundwater in this system. Thus, riparian …

Soil Organic Nitrogen - Investigation of Soil Amino Acids and Proteinaceous Compounds
… pool of proteinaceous compounds in A-horizon soils were significantly high than in C-horizon soils due to the accumulation of organic matter in surface. On average, free amino acids accounted for less than 4 % of hydrolysable amino acids which represent the total proteinaceous …

Woody Species Diversity, Forest and Site Productivity, Stumpage Value, and Carbon Sequestration of Forests on Mined Lands Reclaimed Prior to the Passage of the Surface Mining Control and Reclamation Act of 1977
… total coarse fragments, total available water, C horizon total porosity, and soil profile electrical conductivity. These five properties explained 52 % of the variation in tree growth. Forest productivity of these mined sites was equal to or greater than that of non-mined forests, ranging between …
