Characteristics of Acid Forest Soils in a Mountainous Region with Relatively Low Influence of Acid Deposition
This contribution presents an assessment of acidification and Al speciation in soils of the Novohradske Mountains region (Czech Republic) , an area with relatively low effects of acid deposition. The soils are strongly acid, probably mainly due to spruce growing. Exchangeable Al content was controlled mainly by Ca content in the surface organic horizons (the effect of liming in the 1980s) and by pH in the mineral horizons. Water-extractable Al is bound mainly to non-toxic organic complexes. However, KCl-extractable Al is dominated by toxic Al3+ forms which may present a significant danger in case of some potential changes of soil environment.
