Abstract

The Nutrient Cycling and Soil Acidification Model (NUCSAM) was applied to a spruce site at Solling, Germany, within the scope of a workshop on comparison of forest soil-atmosphere models. Simulated trends and dynamics in the concentrations of sulphatealuminium and pH between 1970 and 1990 compared favourably with time-series of measured data during that period. Dynamics and concentrations of nitrate in the subsoil were overestimated. Simulation results for the period 1990-2090 for two deposition scenarios showed ongoing acidification (pH decrease) of the soil at the present acid load and a rapid response of soil solution chemistry to reduced acid input, but there was a long time delay before favourable Al/Ca ratios were reached.
