Soil mineralogy of an upper coastal plain landscape in Virginia
… intent of this study was to identify the mineralogy present in the proposed mining area and to determine similarities and differences among sampled pedons. Twenty-eight typical pedons were sampled throughout the profile and these samples were prepared for mineralogical analysis. The pedon …

Laboratory characterization of a highly weathered old alluvium in San Juan, Puerto Rico
… Rico, resulting in a special combination of soil mineralogy and structure, with very unusual engineering properties. The soil mineralogy was determined both qualitatively and quantitatively by a series of analytical techniques, consisting of X-ray diffraction, thermal analysis, X-ray …

FTIR Analysis of Bacteria Biomass-Mineral Interactions in Soils
<p>Soil organic carbon (SOC) accounts for 70% of the carbon on Earth. It is therefore a key player in global carbon cycling and climate change (Smith et al., 2008). Soil organic matter (SOM) is an important component of organic matter in soils (SOC), and results from biogeochemical process …

Integrating basic remote sensing, terrain analysis and geostatistical methods to generate spatially explicate continuous soil attribute maps for Fraser Experimental Forest
Hans Jenny's Factors of Soil Formation, a system of quantitative pedology (1941), concisely summarized and illustrated many of the basic principles of pedology utilized to date (Jenny, 1941). This state factor model became the backbone for soil survey research and production because it proposed …

Phosphorus Losses in Runoff from Virginia Soils
… dissolved P losses in runoff are well related to soil test P (STP), thus, various P loss prediction models incorporate the use of a STP vs. runoff DRP relationship. However, the relationship between STP and runoff DRP will vary based on soil type due to differences in soil properties. The purposes …

Slope stability analysis and landslide susceptibility assessment on the SE foot slopes of Mt Cameroon
… analyses of geotechnical properties, soil mineralogy and geochemistry to get an idea of the processes and mechanisms involved in landslide initiation and mobilisation. From these results, two conceptual models are proposed to explain the occurrence of landslides affecting areas …

Physical and chemical properties of artificial soil with humified and non-humified organic matters
… research has been carried out on organic soils which consist of various components of organic matter but the effect of particular organic matter is less reported. This may cause some of the contributing factors of each organic matter are not well understood because each type of organic …

Lime treatment to improve frictional resistance and stability of stiff clay slopes
… movement. The effectiveness of lime treatment of soils has been commonly evaluated in terms of increased unconfined compressive strength; however, if the objective of lime treatment is to improve long-term stability of first-time or reactivated landslides in stiff clays and shales, permanent …

Cadmium accumulation in agricultural soils
Cadmium (Cd) has accumulated in New Zealand (NZ) soils as a result of phosphate fertiliser application. Cadmium is a biotoxic heavy metal and can be adsorbed by soil and enter the human food chain. Three objectives were investigated in this thesis: 1. Determine if the distribution of Cd varies …

Hydrological processes in volcanic ash soils : measuring, modelling and understanding runoff generation in an undisturbed catchment
… characterized by steep hillslopes, volcanic ash soils, undisturbed old growth forest and high rainfall amounts. The investigation of runoff generation processes in this data scarce area is of special interest as a) little is known on the hydrological functioning of the young volcanic ash soils, …
