Young, poorly developed soils

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.

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
  • Gelepts – in very cold climates
  • Cryepts – in cold climates
  • Udepts – in humid climates
  • Ustepts – in semiarid and sub-humid climates'
