Temporal Dynamics of Groundwater Flow Direction in a Glaciated, Headwater Catchment
… of groundwater flow in the soil zone (solum) within the critical zone of a headwater catchment at the Hubbard Brook Experimental Forest in North Woodstock, NH. Groundwater levels were continuously monitored throughout several seasons (March 2019 to Jan 2020) in a network of wells …

A reassessment of the genesis of the Sangamon stone line and texture contrast profile in McDonough County, western Illinois
… The hillslope deposit commonly possesses upper solum characteristics that are interpreted to have developed subsequent to the erosional event. As an alternative to the erosion hypothesis, some texture contrast stone line soils are interpreted to have formed biopedogenically in one parent …

The Evolution of the Profile Paradigm in the History of Pedology and Quaternary Geology: Concepts and Applications
… demands a re-examination of the pedological subsolum region; a region that has been studied closely by Quaternary 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 …

The genesis and characteristics of the fragipan of the Beltsville soils
… type of weathering than the material in the solum. Two horizons high in clay were found in each of the profiles studied: one above the fragipan, which is the present illuvial horizon, and the other below the fragipan, which may be a buried illuvial horizon. In two of the profiles the heavy …

Characterization and quality of soils developing on a mountaintop removal coal mine
… indicated by increasing A horizon thickness, solum thickness, and increased aggregate stability with time. Chemical analyses showed higher N with minesoil age. Minesoils had higher bases, pH, and base saturation than native soils, but native soils had higher carbon, nitrogen, aluminum, and …

Effects of Disturbance History on Forest Soil Characteristics in the Southern Appalachian Mountains
… were significantly deeper and relatively free of solum coarse fragments while SRC soils were shallower and higher in coarse fragments. Subsequent auger observations of three typical pedons on each aspect indicated that soils in LSC were well-developed with gradual horizon boundaries and common …

Soils and morphology of Carolina bays, Eastern Shore, Virginia
… scarp as evidenced by lighter textures, thinner solum depths and paler colors. Clay mineralogical determinations also revealed that soils of bays below the scarp were less weathered as evidenced by less gibbsite and greater amounts of weatherable minerals in subsurface horizons. All soils …

New Zealand nursing students’ experiences of ethical issues in clinical practice: A descriptive study
… recognise the unique problems students face (Solum, Maluwa & Severinsson, 2012). There has been no documented research to date that explores New Zealand undergraduate nursing students’ experiences of ethical issues in clinical practice. AIM OF THE RESEARCH The purpose of this descriptive study …

An approach to studying soil-landscape relationships in Virginia
… formation, and saprolite accumulates below the solum. Reconstruction analysis was found to be a valuable tool in studying soil-landscape relationships.

Estimating Evapotranspiration of a Riparian Forest Using Sap Flow Measurements
<p>To close the water use budget of irrigated agricultural fields in floodplains with substantial riparian corridors, it is necessary to understand groundwater usage by dominant phreatophytic vegetation, particularly when the primary source of water for irrigation comes from groundwater …
