Temporal changes of acidification status of mountainous forest soil with emphasis on aluminium
Original language description
The aim of this contribution is to describe temporal chemical changes in the forest mountainous soils under three different vegetation covers between 2008 and 2013. Overall, soils were assessed as strongly acid and Al was the prevailing exchangeable cation. Organic horizons exhibited lower pH than mineral horizons indicating that they are more sensitive to external factors such as vegetation cover and atmospheric deposition. The soil sorption capacity decreased with increasing depth. Mineral horizons were unsaturated by bases. In general, soils under beech forest and in clear-cut areas exhibited more favourable soil chemical characteristics compared to spruce forest soil, which showed the lowest soil pH, lowest base saturation and lowest Ca:Al ratio, and thus possesses the highest exchangeable acidity. Changes between the investigated years show an upward temporal trend in Al content and base saturation, and decreasing exchangeable acidity for each stand in organic horizons. On the contrary, mineral horizons showed ongoing soil acidification and leaching of base cations.
