Methodische Probleme bei bodenchemischen Untersuchungen an Böden aus dem Liefdefjord/Bockfjord-Gebiet (NW-Spitzbergen) / Liane Weber, Wolf Dieter Blümel.
Title: | Methodische Probleme bei bodenchemischen Untersuchungen an Böden aus dem Liefdefjord/Bockfjord-Gebiet (NW-Spitzbergen) / Liane Weber, Wolf Dieter Blümel. |
Translated title: | Methodistical problems in investigating chemistry of soils in the Liefdefjord/Bockfjord region (NW Spitsbergen). |

Abstract: | Method of successive Fe extraction is used to show intensity of chemical weathering by oxidation in soils of Liefdefjord/Bockfjord area. To measure selectivity of different extraction techniques dissolution profiles are found. Bv horizons have greater Fe values than Cv horizons so formation of pedogenic Fe oxides is deduced, but dissolution profiles show that both techniques can dissolve large amounts of Fe from its minerals. Data of oxalate and dithionite-citrate extraction alone cannot give correct intensity of oxidation process. Mineralogical analysis is necessary. |
