Soil-Forming Processes
Cryoturbation is the dominant soil-forming process in the circumarctic.
Additional processes of importance are biological enrichment of base cations,
paludization, podzolization, gleization, melanization, cambisolization, and
base cation leaching. Processes such as argilluviation, andisolization,
