The contribution of manganese oxides to redox buffering in selected soils of the South African Highveld
… and saturated soil conditions. The use of redoximorphic features as a soil wetness indicator is widely practiced. The reduction of Fe3+ to Fe2+, resulting in the formation of these features, is particularly diagnostic for wetland soils. The problem arises when investigating a soil that …

Morphology, Mineralogy, and Hydrology of Soils in the Triassic Culpeper Basin of Maryland
… materials are known to retard the development of redoximorphic features within their sola. This retardation phenomena may lead to misinterpretations of these soils for both agricultural and engineering purposes. Such soils occur within the Triassic Culpeper Basin of Maryland. Eleven pedons along …

Beneficial Reuse of Dredged Materials in Upland Environments
… oxidized horizon with an abundance of redoximorphic features. During the study period, the soil chemistry of the weathering dredged materials shifted from Na-dominated to Ca and Mg-dominated system, allowing plant invasion. In the second part of the study, a bench-scale greenhouse …

Determining an Appropriate Organic Matter Loading Rate for a Created Coastal Plain Forested Wetland
… of hydric soil development, 2) the formation of redoximorphic features, and 3) the growth and vigor of hydrophytic vegetation. The study contained wet (CCW-Wet) and dry (CCW-Dry) experiments, each receiving 6 compost treatments (0 Mg/ha untilled and 0, 56, 112, 224, and 336 Mg/ha tilled). Over …

Hydropedology of Problematic Interfluve Transported Soils in the Central Virginia Piedmont
… Piedmont of Virginia containing chroma ≥ 3 redoximorphic features (RMFs) can be difficult. It is imperative to understand their saturation regimes because onsite wastewater disposal systems, which are sited based upon soil evaluations, have failed prematurely when installed into these …

An Analysis of Palustrine Mitigation Wetlands in the Virginia Coastal Plain
… under the current hydrologic conditions. These features were more abundant and more prominent in areas saturated at or above the surface for longer periods of time. Overall, site differences between mitigation and reference areas are mainly due to construction practices and a lack of organic …

Pedogenesis and geomorphic implications of soils developed on Blue Ridge alluvial fans, Virginia
… the upper Depositional unit (unit A). Reticulate redoximorphic features and highly weathered quartzite rocks are found in the 2Bt horizons (unit B) where clay approaches 60 percent at 2m. Up to 25 pedons were sampled within a 50 m² grid at four Sites. Paired samples from the pedons were analyzed …

Evaluation of the Effects of Absorption Field Product Architecture Type on Effluent Dispersal and Soil Chemical Properties in a Profile-Limited Soil
… siliceous, active, mesic Typic Fragiudult) with redoximorphic features indicating a seasonal water table at various depths. Loading rates were determined using soil morphological indicators and the maximum allowable rate under State of Arkansas regulations. Product performance was evaluated based …

Physical and Hydrologic Responses of an Intensively Managed Loblolly Pine Plantation to Forest Harvesting and Site Preparation
… soil structural changes and increased redoximorphic features caused by soil disturbance. The disturbed soil layers in recently created traffic ruts consisted of exposed and severely disturbed subsurface soils, but this layer was naturally ameliorated 2 years after the disturbance. …

Soil Genesis and Vegetation Response to Amendments and Microtopography in Two Virginia Coastal Plain Created Wetlands
Wetlands serve important ecosystem functions such as carbon sequestration but are often affected by disturbances like urban development, agriculture, and road building. For wetlands created to mitigate losses, it is important that the ecosystem functions successfully replicate those of natural …
