Depth function of manganese (Mn) concentration in soil solutions: Hydropedological translocation of trace elements in stratified soils

摘要: Periglacial cover beds are an important trigger of slope-water paths in sloped terrain the mid-latitudes. Most hydropedological studies focus on quantitative analysis about interrelation between subsurface layering and runoff processes at slope scale. In this research we emphasis a qualitative environmental geochemical trace elements dissolved organic carbon small forest hydrological study area central parts subdued mountains Germany (Location: KrofdorferForst, +50° 41' 3.69", +8° 38' 38.87"). The main objective is to assess effect lithological discontinuities stratified soils within depth functions concentration soil solutions (soil water its mobile fraction vertical distribution). Lorz (2008) show that manganese (Mn) characterized by strong pedogenic dynamics, analysing shortened sequential extraction solid material. We investigated hypothesis act like aquicludes. Therefore expect abrupt changes function as result such water-blocking (= barriers) consequence mobilization under wet conditions. preliminary case sampled from three different plots 400m-toposequence. use situ trench installed suction lysimeters with ceramic tips (Irrometer Soil Solution Access Tube) extract samples each 20 cm top- (10 cm) subsoil (110 cm). For element inductively coupled plasma mass spectrometry (ICP-MS). results: A clear character could be illustrated for most plots. example, upper plot contrast 1013 ppb mean 50 profile 290 70 (17 month sampling period). To conclude, these results demonstrate hydrochemical quality translocation determining run off - respectively seen it.
