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]
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 Sassafras soil series is one of the oldest in the United States and has great historical significance to modern-day soil science.It was recognized as Maryland's state soil in 1901 and is now identified as a Benchmark (a soil that has large extent in major resource areas) and Hall of Fame soil series, which is a recognition given to a soil series for having a critical role in the evolution ...
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. Also, representative soils have been selected for Puerto ...
Bluegrass region. Kentucky's Inner Bluegrass region features hundreds of horse farms. The Bluegrass region is a geographic region in the U.S. state of Kentucky. It makes up the central and northern part of the state, roughly bounded by the cities of Frankfort, Paris, Richmond and Stanford. [1] It is part of the Interior Low Plateaus ecoregion.
Cecil (soil) Originally mapped in Cecil County, Maryland in 1899, more than 10 million acres (40,000 km 2) of the Cecil soil series (Fine, kaolinitic, thermic Typic Kanhapludults) are now mapped in the Piedmont region of the southeastern United States. It extends from Virginia through North Carolina (where it is the state soil), South Carolina ...
Hardpan. 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 ...
The Storie index is a method of soil rating based on soil characteristics that govern the land's potential use and productivity capacity.Developed by R. Earl Storie at University of California, Berkeley in the 1930s as a method of land valuation, it is independent of other physical or economic factors that might determine the desirability of growing certain plants in a given location.
