Annotation:

Long-term and short-term response to acid deposition of poor sandy podzols under pine and birch forests near the nickel smelter in the Kola Peninsula, the north-western part of Russia, was evaluated with the SMART model. The present acid load does not effect considerably on forest soils in background areas. The dramatic shift in soil chemistry near the smelter is expected within several decades. According to the calculations the powerful mass-flow of melt water in spring may release in sharp soil acidification. At least 90% of the total SO2 emissions has to be reduced to avoid exceedance of critical values of soil chemical properties and possible serious ecological consequences.
