A Retisol is a Reference Soil Group of the World Reference Base for Soil Resources (WRB).[1] Retisols are characterized by clay migration and an additional specific feature: The clay-poorer and lighter coloured eluvial horizon intercalates netlike into the clay-richer more intensely coloured illuvial horizon. The illuvial horizon is the diagnostic argic horizon, and the intercalation is called retic properties (Latin: rete = net).
Retisols were newly introduced with the third edition of the WRB in 2014. They include the narrower defined Albeluvisols[2] of the first and second edition (1998 and 2006), which were abolished in 2014. The definition of the Retisols resembles the definition of the Podzoluvisols of the Legend (1974) and the Revised Legend (1988) of the FAO soil classification.
