Menfro is the state soil of Missouri. [1] [2] [3] It was the first soil to go on display when Scientists from the Natural Resources Conservation Service of the USDA, the Soil Science Society of America and others worked with exhibit designers from the Smithsonian Institution on a display of soil monoliths from every state.
For each soil monolith, there is supplemental information about the site of sampling (e.g. landscape, land use, parent material and climate), a detailed profile description for each soil horizon or layer, and data on chemical compositions and physical features. The museum displays examples of the main (32) WRB Soil Reference Groups of the World ...
Before 1955, Canadian soil testing was based on systems of classification which were similar to methods being used in the United States. In 1955, a taxonomic system of soil classification specific to Canadian conditions was introduced. [2] This system was designed to differentiate soils created by pedogenic processes in cool climatic ...
ISRIC - World Soil Information, also known as the International Soil Reference and Information Centre, is a science-based independent foundation.It was established in 1966, following a recommendation by the International Society of Soil Science (ISSS, now known as the International Union of Soil Sciences (IUSS)) and the United Nations Educational, Scientific and Cultural Organization (UNESCO).

The soil contained in the field lysimeter can either be collected as a monolith (i.e., in one piece) or be reconstructed from the different layers present at the sampling site. Most lysimeters contain an opening at the bottom allowing the leachate to be collected and analyzed over time.
A monolith is a geological feature consisting of a single massive stone or rock, such as some mountains. Erosion usually exposes the geological formations, which are often made of very hard and solid igneous or metamorphic rock. Some monoliths are volcanic plugs, solidified lava filling the vent of an extinct volcano.
People on Nias in Indonesia move monoliths to a construction site, c. 1915. This is a list of monoliths organized according to the size of the largest block of stone on the site. A monolith is a large stone which has been used to build a structure or monument, either alone or together with other stones. In this list at least one colossal stone ...
Inceptisols of the world Some soils in urban environments fall into the Inceptisol order (soil suborder Anthrept) Inceptisols are a soil order in USDA soil taxonomy. They form quickly through alteration of parent material. They are more developed than Entisols. [1] They have no accumulation of clays, iron oxide, aluminium oxide or organic matter.
