In Slovakia, soil acidification remains an environmental and forestry related issue despite a sharp decrease in the S02. Recent monitoring of critical acid loads of Slovak forests show that around one third of Slovak forests are directly affected by acidification. In this situation, an increased biomass extraction from forests for energy generation purposes, considered by some decision-makers, poses a serious threat to geobiochemical cycles and may further aggravate the effect of the emissions on soils. In other parts of the country however, the drop in pH value means a soil degradation in sense of soil forming processes rather than in reference to forest production. This fact is also confirmed with the values of growing stock in Slovak forests, continually increasing since 1920.
