Description
In the World Reference Base for Soil Resources (WRB), most gelisols belong to the cryosols. In soil taxonomy, gelisols key out before the histosols. In the WRB, the histosols key out before the cryosols. Organic permafrost soils are therefore gelisols (histels) in the soil taxonomy and histosols (cryic histosols) in the WRB.
