fate of chromium and nickel in subalpine soils derived from serpentinite

Weathering of serpentinitic parent material, naturally rich in both Cr and Ni, provides soils that generally contain elevated concentrations of both metals. In this study, soil development as well as the fate of Cr and Ni in Dystric Eutrochrepts derived from serpentinitic rock slide material were in...

Zusammenfassung:Weathering of serpentinitic parent material, naturally rich in both Cr and Ni, provides soils that generally contain elevated concentrations of both metals. In this study, soil development as well as the fate of Cr and Ni in Dystric Eutrochrepts derived from serpentinitic rock slide material were investigated in the Swiss Alps under subalpine climatic conditions. Exchangeable Ni was ≤ 0.2 mmol kg −1 , but exchangeable Cr was always
