Abstract:

Behaviors of 9 chemical elements Si, Al, Fe, Ca, Mg, Mn, K, Na, P within three soil profiles respectively representative of Dystri gelic Cambisol, Fibri gelic Histosol, Relic Ornithosol and their enrichment and migration in the soil horizons were quantitatively demonstrated by the method of the enrichment coefficient analysis. The results obtained suggest that enrichment and migration of elements differ greatly within profiles of three soil types on Fildes Peninsula. Some elements become intensively enriched within some soils while they get strongly lost from other profiles. It is believed that biological factors play an important role in the enrichment of several elements within some soil profiles. And, as a result of the occurrence of surface and soil water during the three month austral summer, evident percolation and leaching movement cause significant difference in abundance levels of a certain element between different depths. For a better understanding of pedochemistry of the studied elements, the concept of redistributing enrichment coefficient was employed to illustrate the element redistribution between soil and clay fraction along with soil development.
