Biogeochemistry of forest catchments with contrasting geology
Original language description
The objective was to compare and contrast element pools and fluxes in two catchments with similar topography, vegetation, climate, and atmospheric deposition, but different lithology (leucogranite vs. serpentinite). The leucogranite site Lysina showed low concentrations of exchangeable base cations on the soil exchange complex and in stream water. Supplies of base cations from atmospheric deposition and soil processes were smaller than inputs of sulfate on an equivalence basis, resulting in low pH and high concentration of toxic Al in drainage water. Visible symptoms of forest decline by needle yellowing were caused by Mg deficiency at Lysina. In contrast, the serpentinite site exhibited near neutral stream water pH, despite elevated inputs of acidic deposition. Slow tree growth appears to be caused by K deficiency, Mg oversupply and Ni toxicity.
