This is a list of U.S. state soils. A state soil is a soil that has special significance to a particular state. Each state in the United States has selected a state soil, twenty of which have been legislatively established. These official state soils share the same level of distinction as official state flowers and birds.
Calcareous soils are relatively alkaline, in other words they have a high pH. They are characterized by the presence of calcium carbonate in the parent material; the carbonate-ion is a base. Additionally, these soils may have a calcic horizon, a layer of secondary accumulation of carbonates (usually calciumcarbonate or magnesiumcarbonate) in ...
A post office called Chalk Level was established in 1848, and remained in operation until 1914. [2] The community most likely was so named on account of the chalky character of the soil at the flat town site. [3] It is also rumored that the city got its name from its "level headed" residents who could "chalk" it down.
In soil science, agriculture and gardening, hardpan or soil pan is a dense layer of soil, usually found below the uppermost topsoil layer. [1] There are different types of hardpan, all sharing the general characteristic of being a distinct soil layer that is largely impervious to water. Some hardpans are formed by deposits in the soil that fuse ...
Menfro strata. Menfro soil is a series of deep, well drained, moderately permeable soils formed in 6-to-20-foot (1.8 to 6.1 m) thick loess deposits. It is found in central and eastern Missouri and west-central and southwestern Illinois on upland ridgetops, backslopes, and benches adjacent to the Missouri and Mississippi rivers and their major tributaries.
In agriculture, chalk is used for raising pH in soils with high acidity. [25] Small doses of chalk can also be used as an antacid. [26] Additionally, the small particles of chalk make it a substance ideal for cleaning and polishing. For example, toothpaste commonly contains small amounts of chalk, which serves as a mild abrasive. [27]
Alison LaCroix, professor of constitutional law at the University of Chicago Law School, told ABC News that the power to regulate and implement key laws lies strictly within the states and many ...
The paper was first coated with a chalk-like powder, and the ink for the stamp was then impressed upon the paper. Collectors are cautioned not to attempt to remove a stamp printed on chalky paper from an envelope or paper backer by soaking it in fluid, as this may destroy the stamp's design. A simple test for chalky paper is to rub a silver ...
