Inceptisol

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. They have an ochric or umbric horizon and a cambic subsurface horizon.

Inceptisols of the world

Some soils in urban environments fall into the Inceptisol order (soil suborder Anthrept)

In the World Reference Base for Soil Resources (WRB), most Inceptisols are Cambisols or Umbrisols. Some may be Nitisols. Many Aquepts belong to Gleysols and Stagnosols.^[2]

Suborders

• Aquepts – with a water table close to the surface
• Anthrepts – with a plaggen or anthropic epipedon, a sign of intense and prolonged human activity
• Gelepts – in very cold climates
• Cryepts – in cold climates
• Udepts – in humid climates
• Ustepts – in semiarid and sub-humid climates'
• Xerepts – in areas with very dry summers and moist winters
