FAO soil classification (Pedology 🟤)
The Food and Agriculture Organization of the United Nations developed a supra-national classification, which offers useful generalizations about pedogenesis in relation to the interactions between the main soil-forming factors. It was first published in form of the UNESCO Soil Map of the World. Many of the names offered in that classification are known...

Port Silt Loam (Pedology 🟤)
Port Silt Loam is the state soil of Oklahoma. This type of soil is reddish in color due to the weathering of reddish sandstones, siltstones, and shales of the Permian period. It is a medium-textured alluvial soil deposited along flood plains. Port Silt Loam can be found in 33 of the 77 counties in Oklahoma and covers around one mil...

Soil carbon feedback (Pedology 🟤)
The soil carbon feedback concerns the releases of carbon from soils in response to global warming. This response under climate change is a positive climate feedback. There is approximately two to three times more carbon in global soils than the Earth's atmosphere, which makes understanding this feedback crucial to understand fut...

Paleopedological record (Paleontology 🦕)
The paleopedological record is, essentially, the fossil record of soils. The paleopedological record consists chiefly of paleosols buried by flood sediments, or preserved at geological unconformities, especially plateau escarpments or sides of river valleys. Other fossil soils occur in areas where volcanic activity has covered the ancient soils.

Laterite (Pedology 🟤)
Laterite is a soil type rich in iron and aluminum that often forms in hot, wet areas; most such soil is found in the tropics. Nearly all laterites are of rusty-red coloration due to high iron oxide content. Laterite soils develop by intensive and prolonged weathering of the underlying parent rock, usually under conditions of high temperatures and heavy rainfall...

Ranker (soil) (Pedology 🟤)
Ranker is soil developed over non-calcareous material, usually rock. It is regarded in some soil classifications as lithomorphic, a group which also includes rendzina, similar soil over calcareous material. It is often called A/C soil, as the topsoil, or A horizon, is immediately over a C horizon. == References...

Hwangto (Pedology 🟤)
Hwangto, a Korean loess soil, is a yellow-coloured soil, which contains high levels of potassium chloride and calcium. Hwangto is sometimes called a 'living soil' for its medical effects. Korean loess called “Hwangto”or “the red yellow soil or earth” has been a basic element or nourishment which has cultivated Korean nature and cultural heritages. Hwangto reve...

Planosol (Pedology 🟤)
A Planosol in the World Reference Base for Soil Resources is a soil with a light-coloured, coarse-textured, surface horizon that shows signs of periodic water stagnation and abruptly overlies a dense, slowly permeable subsoil with significantly more clay than the surface horizon. In the US Soil Classification of 1938 used the name Planosols, whereas its successor, the USDA soil taxonomy, includes ...

Fragipan (Pedology 🟤)
A fragipan is a diagnostic horizon in USDA soil taxonomy. They are altered subsurface soil layers that restrict water flow and root penetration. Fragipans are similar to a duripan in how they affect land-use limitations. In soil descriptions, they are commonly denoted by a Bx or Btx symbol. They often form in loess ground. The first record of fragipans is probably that by John Hardcastle in New Zealand in the ...

Andosol (Pedology 🟤)
Andosols are soils found in volcanic areas formed in volcanic tephra. In some cases Andosols can also be found outside active volcanic areas. Andosols cover an estimated 1–2% of Earth's ice-free land surface. Andosols are a Reference Soil Group of the World Reference Base for Soil Resources. They are closely related to other types of soils such as Vitrosols, Vitrandosols, Vitrons and P...

Hilo (soil) (Pedology 🟤)
Hilo soil is the official state soil of the state of Hawaii. These soils cover about 21,000 acres and are considered prime agricultural land. The Hawaiian definition of the word “Hilo” is “first night after the new moon.” Also, the word is the Polynesian term for “Navigator,” and the name of a town, Hilo, Hawaii.

Sapric (Pedology 🟤)
A sapric is a subtype of a histosol wherein virtually all of the organic material has undergone sufficient decomposition to prevent the identification of plant parts and even fecal matter. Muck is a sapric soil that is naturally waterlogged or is artificially drained.

Grit (supplement) (Pedology 🟤)
Grit is a material eaten by birds to aid in their diets and digestion. Wild birds find grit naturally while foraging, and farmers can purchase grit for their domestic fowl. There are two forms: soluble grit, which dissolves in a bird's digestive system and is often made of calcium; and insoluble grit, which remains in the gizzard and is usually composed of stone. G...

Charlottetown (soil series) (Pedology 🟤)
Charlottetown soil series is the name given to a deep fine sandy loam soil which has developed under forest vegetation on glacial till. This series occurs only on Prince Edward Island, where it is widespread and so important for agriculture that it has been designated as the Provincial Soil. This soil is an Orthic Humo-Ferric Podzol i...

International Committee on Anthropogenic Soils (Pedology 🟤)
The International Committee on Anthropogenic Soils was a committee active beween 1995 and 2013 concerned with classifying soils derived from human activity. According to the National Resources Conservation Service, the committee’s major contribution was "improv...

Pedosphere (Pedology 🟤)
The pedosphere 'ground, earth' and σφαῖρα 'sphere') is the outermost layer of the Earth that is composed of soil and subject to soil formation processes. It exists at the interface of the lithosphere, atmosphere, hydrosphere and biosphere. The pedosphere is the skin of the Earth and only develops when there is a dynamic interaction between the atmosphere, biosphere, lit...

Imogolite (Pedology 🟤)
Imogolite is an aluminium silicate clay mineral with the chemical formula Al2SiO34. It occurs in soils formed from volcanic ash and was first described in 1962 for an occurrence in Uemura, Kumamoto prefecture, Kyushu Region, Japan. Its name originates from the Japanese word imogo, which refers to the brownish yellow soil derived from volcanic ash. It ...

Plinthosol (Pedology 🟤)
Plinthosols are a reference soil group in the World Reference Base for Soil Resources, developed by the Food and Agriculture Organization. They are characterized by the presence of plinthite, petroplinthite, or pisoliths—concretions formed through pedogenic processes involving the accumulation of iron oxides. A key diagnostic feature of these soils is the plinthic horizon, which begins withi...

Pedology (Pedology 🟤)
Pedology is a discipline within soil science which focuses on understanding and characterizing soil formation, evolution, and the theoretical frameworks for modeling soil bodies, often in the context of the natural environment. Pedology is often seen as one of two main branches of soil inquiry, the other being edaphology which is traditionally more agronomically oriented and focuses on ho...

Canadian system of soil classification (Pedology 🟤)
The Canadian System of Soil Classification is more closely related to the American system than any other, but they differ in several ways. The Canadian system is designed to cover only Canadian soils. The Canadian system dispenses with the sub-order hierarchical level. Solonetzic and Gleysolic soils are d...

Gypsisol (Pedology 🟤)
Gypsisols in the World Reference Base for Soil Resources are soils with substantial secondary accumulation of gypsum. They are found in the driest parts of the arid climate zone. In the USDA soil taxonomy they are classified as Gypsids, in the Russian soil classification they are called Desert soils. Gypsisols are developed in mostly unconsolidated alluvial, colluvial and aeolian deposits of base-...
