Entisols (from recent – new) are the last order in soil taxonomy and exhibit little to no soil development other than the presence of an identifiable topsoil horizon.
These soils occur in areas of recently deposited sediments, often in places where deposition is faster than the rate of soil development.
Some typical landforms where Entisols are located include: active flood plains, dunes, landslide areas, and behind retreating glaciers. They are common in all environments.
Entisols make up the second largest group of soils after Inceptisols, occupying about 16% of the Earth’s surface.
