savikerros
Savikerros is a term used in Finnish soil science to describe a soil layer in which the clay content increases markedly compared with the layers above and below it. The term is commonly applied to horizons formed by clay illuviation, often corresponding to a Bt or argic horizon in broader soil classification.
Formation and occurrence: Savikerros typically develops when clay minerals are transported with water from upper, coarser
Properties: A savikerros has high fine particle content, increased plasticity when moist, and relatively low permeability
Implications: For land use and engineering, a savikerros can affect drainage efficiency, perched water tables, and
In Finnish soil literature, savikerros serves as a practical description of a clay-enriched horizon and is
