Wasser- und Elementtransport in einem Stagnogley am Hang der Bärhalde (Schwarzwald,Deutschland)

Water and Element Movement in a Stagnogley on the Slope of the Bärhalde Range (Black Forest, Germany) The soil water balance of this stagnogley (planosolic humic gleysol) is dominated by the very humid and cool climate, by the indurated subsoil and the solid parent granite as well as by its position on the lower slope of the Bärhalde ridge. Inspite of the high saturated water conductivity the drainage is impeded causing permanent waterlogging (average watertable at 55 cm below surface). Lateral flow through the soil exceeds seepage by 150 times. Inspite of the high input by lateral flow from the higher podzol area most of the major elements show reasonable losses throughout the profile. Other elements have losses in the topsoil which are compensated in the subsoil by gain from the lateral flow (Al, Be, Si). Especially elements with a mobility independent from redoxpotential have been accumulated throughout the entire period of soil formation (Pb, Zn). Some other trace elements accumulate recently because of increasing immissions (Cd, Cu, Co). Over all elements lateral flow through the profile exceeds vertical transport by 30 to 400 times.
