Abstract
Two acid watersheds in the Vosges mountains (N.E. France), one with a podzo l, the other with an acid brown soil, were monitored by analysing soil solu tions and two related springs for total chemistry and Al speciation. High c oncentrations of inorganic Al did not occur in the podzol upper horizons bu t were evident in the corresponding spring, together with low concentration s of Ca. In the acid brown soil area, high concentrations of inorganic Al o ccurred in the leaching water draining the upper soil horizons, but not in the undrained water nor in the spring, the latter exhibiting rather high Ca content. In both watersheds, needle yellowing in conifers could be observe d and might be ascribed to Mg deficiency rather than to Al toxicity. (C) 20 00 Elsevier Science Ltd. All rights reserved.
