Soil development in cold desertic zones and antarctic environments in Chile

Walter Luzio L.1, Wilfredo Vera E.1 y Maria Adriana Carrasco R.1

Several soil profiles have been seleeted from highlands inthe northern part of Chile and in ReyJorge Island, South Shetland Islands, antaretic region, in arder to compare soil development in both environments, Organic carbon, cation exchange capacity, eleetrie conduetivity and diagnostic horizons haya been discussed in this paper. Thawing/freezing cycles permit haploidization in soil profiles at Rey Jorge Island, Soils from the northern part of Chile were classified as Cryorthents and Camborthids while those from antaretic region were classified as Cryorthents.
