SOIL CRACK MORPHOLOGY AND SOIL SALINITY1
Soil Science, 1992This study considers the effects of soil salinity on soil crack morphology, soil bulk density, and water content in the field where soil cracking is not affected by the plant canopy or plant water extraction. Field measurements along transects of three different salinity treatments were taken 3, 6,

Effects of Soil Morphology on Hydraulic Properties I. Quantification of Soil Morphology
Soil Science Society of America Journal, 1999Utilization of existing soil survey databases for characterizing water flow and solute transport in field soils has practical value. However, the lack of a proper means for quantifying soil morphology limits the incorporation of soil structural information into models. In this study, we examined basic relationships between five major soil morphological

SOIL MORPHOLOGY AND SOIL PHYSICAL PROPERTIES. I. SOIL AERATION
Canadian Journal of Soil Science, 1972The relation between soil structure and soil aeration was investigated on undisturbed soil cores from soil horizons exhibiting six distinct kinds of soil structure (prismatic, columnar, blocky, granular, platy, massive) over a broad range of soil texture.

Teaching soil morphology to introductory soil science students
Journal of Agronomic Education, 1988ABSTRACTIntroductory soil science students should receive practical instruction in soil morphology because it can be a tool to assess soil limitations for various land uses. “Real soils” should be examined whenever possible. Soil cores collected from a toposequence are well‐suited for classroom instruction because the soils frequently exhibit a wide ...

Publisher Summary Morphology is the most important feature used to differentiate Vertisols from other soil orders. The major morphological markers of Vertisols are linear and normal gilgai (micro-relief), cyclic horizons, surface cracking upon desiccation, and slickensides.

Surface-water gley soils in Bangladesh: Environment, landforms and soil morphology
Geoderma, 1977Abstract Most of Bangladesh is seasonally flooded or waterlogged, mainly by rain water. Surface-water grey soils are extensively developed on the seasonallywet landscapes. They are acid, hydromorphic soils with albic horizons containing less clay than the deeper horizons, and with a seasonally fluctuating pH in the surface horizon.

Fragipan Soils: Morphological Relationships
Soil Science Society of America Journal, 1964Abstract Field descriptions and certain laboratory data for 17 soil profiles representing Bedford, Calloway, Dickson, Grenada, Henry, Mercer, and Tilsit series in Kentucky were obtained. All of the soils contain fragipan horizons.

Forest Windthrows and Their Influence on Soil Morphology
Soil Science Society of America Journal, 1973Abstract The variability in thickness of the O and A2 horizons was studied on a sandy loam forest soil in the Great Lakes‐St. Lawrence Region of southern Ontario. Horizon thicknesses were recorded in 1.3 cm (0.5 inch) classes for each 10.2 cm (4 inches) of horizontal distance on the faces of each soilpit.

Surface Morphology of Quartz and Age of Soils
Soil Science Society of America Journal, 1977Abstract The surface morphology of quartz sand grains from soils developed from Wisconsin, Illinoian, and Kansan age glacial material and on residual parent materials were studied using scanning electron microscopy. Both solution and precipitation surfaces were observed.
