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.

Tifton (soil) (Pedology 🟤)
Tifton soil is the official state soil of the state of Georgia.
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.
