Abstract
Background and Purpose: Currently, only 4.4% of the forested area in Croatia has been mapped in terms of the critical load of acidity, with exceedances reported for a couple of sites in the region of Gorski Kotar However, some sensitive areas such as the eastern part of Croatia, have not yet been mapped and as a result the exceedance of the critical load of acidity could be much larger than the one currently reported. Therefore, it is important to assess the prospects of a regional assessment of forest soil chemistry with dynamic acidification models that can answer questions related to the recovery of forest soils after a drop in the acid atmospheric load. Materials and Methods: We applied the dynamic biogeochemical model SAFE to a... (More)

Therefore, it is important to assess the prospects of a regional assessment of forest soil chemistry with dynamic acidification models that can answer questions related to the recovery of forest soils after a drop in the acid atmospheric load. Materials and Methods: We applied the dynamic biogeochemical model SAFE to a forested site in the region of Mt. Medvednica, Croatia, with input data obtained from available national databases and the published literature. Results and Conclusions: Simulation results showed that the soil at the site did acidify, with pH and base saturation decreasing significantly from pre-industrial levels. The simulated soil [Bc]/[Al] molar ratio exceeded the critical limit in the second (Bw) and third (BwC) soil horizon, indicating that the forest at the site will likely encounter adverse effects. However, under the current deposition scenario, the site will recover fully from acidification by 2026. This modelling exercise pointed out that existing national datasets are not sufficient to fully parameterize SAFE. Therefore, the SAFE model might not be currently suitable for a regional assessment of forest soil acidification and recovery in Croatia. (Less)
