| Zusammenfassung |
| In the Speuld forest, the Netherlands, the dynamic soil
acidification model NuCSAM has been applied to a manipulation experiment in which part of
the forest was roofed to control nitrogen (N) and sulphur (S) deposition. The roofed area
was divided into two subplots watered artificially; one received ambient N and S
deposition and one with pristine N and S deposition. Concentration measurements on each
plots showed a high (time-dependent) spatial variability. Statistical analyses of the
concentrations on both subplots showed small but significant effects of the reduction in
deposition on nitrate (NO3) sulphate (SO4) and aluminum (Al)
concentrations. The statistical significance of the effects was minimised by the large
spatial variability within the plots. Despite these shortcomings, simulated concentrations
were generally within the 95% confidence interval of the measurements although the effect
of a reduction in N deposition on soil solution chemistry was underestimated due to a
marked decline in N-uptake by the vegetation. |
