Soil types by clay, silt and sand composition as used by the United States Department of Agriculture. Loam (in geology and soil science) is soil composed mostly of sand (particle size > 63 micrometres (0.0025 in)), silt (particle size > 2 micrometres (7.9 × 10 −5 in)), and a smaller amount of clay (particle size < 2 micrometres (7.9 × 10 −5 in)).
A fourth term, loam, is used to describe equal properties of sand, silt, and clay in a soil sample, and lends to the naming of even more classifications, e.g. "clay loam" or "silt loam". Determining soil texture is often aided with the use of a soil texture triangle plot. [5] An example of a soil triangle is found on the right side of the page.
The Natural Resources Conservation Service describes Crider as a soil series with "very deep, well drained, moderately permeable soils on uplands. They formed in a mantle of loess and the underlying limestone residuum ." [1] [6] It is known to be present in Kentucky, Indiana, Illinois, Missouri, Ohio, and Tennessee. [1]
The AASHTO Soil Classification System was developed by the American Association of State Highway and Transportation Officials, and is used as a guide for the classification of soils and soil-aggregate mixtures for highway construction purposes. The classification system was first developed by Hogentogler and Terzaghi in 1929, [ 1] but has been ...
Rudolf Abel and Francis Gary Powers. In probably the most dramatic swap of the Cold War era, Abel and Powers were exchanged on Feb. 10, 1962, on the Glienicke Bridge connecting the U.S.-occupied ...
The physical properties of soil, in order of decreasing importance for ecosystem services such as crop production, are texture, structure, bulk density, porosity, consistency, temperature, colour and resistivity. [1] Soil texture is determined by the relative proportion of the three kinds of soil mineral particles, called soil separates: sand ...
Loam, Kentucky. / 37.40750°N 84.12972°W / 37.40750; -84.12972. Loam is a ghost town located in southwestern Jackson County, Kentucky, United States. The town was located along Horse Lick Creek. It is located southwest of McKee by 7 miles, and 2.7 miles northwest of another ghost town, Dango. [2] The town is located on Bethel Church ...
In soil science, soil gradation is a classification of a coarse-grained soil that ranks the soil based on the different particle sizes contained in the soil. [1] Soil gradation is an important aspect of soil mechanics and geotechnical engineering because it is an indicator of other engineering properties such as compressibility , shear strength ...
