Conclusions • Quantification of lithologic controls on regolith, mineral soil and organic soil in (2+21) forest catchments (in monolithologic and tree monoculture environment of central Europe) • Selected paired monolithologic catchments include end-members of ecosystem sensitivity to acidification • Comparison of spatial scales of chemical weathering from laboratory microscale, soil profiles to small catchments

  43. Very different proportions of Mg fluxes in throughfall at sites with Mg-poor (LYS) and Mg-rich (PLB) substrate in 1992-2002 Lysina Pluhuv Bor

  44. Decline of internal cycling and dry deposion fluxes of base cations in throughfall in 1994-2002. The pattern of internal cycling follows the large increase of throughfall pH. However the wet deposition fluxes remain stable. Dry deposition flux of base cations was larger than the wet deposition flux in the middle of 1990s, but not later. Lysina Pluhuv Bor
