“…and Palicnik (944 m a.s.l.). These transects were studied earlier in detail by Pavlů et al (2007) (10 soil profiles at each transect), and later on, by Borůvka et al (2009) (5 soil profiles at each transect). However, they measured only some physical and chemical properties of all diagnostic horizons of all soil profiles: pH; effective cation exchange capacity; content of cations in the sorption complex; A400/A600 as humus quality parameter; content of available Ca, Mg, K, P; pseudototal content of Ca and Mg; amount of crystalline forms of Al and Fe, content of two differently extracted Al forms and speciation of potentially dangerous Al forms.…”

“…with northern orientation (Table 1). Soil samples were collected from three soil profiles (of 5 soil profiles studied by Borůvka et al, 2009) along this transect. Forest cover changes with decreasing altitude, from an area where spruce forest died in 1980s and early 1990s due to strong acid deposition and was replaced with young (now approximately 10 years old) free-growing spruce and with high grass abundance (mainly Calamagrostis villosa (Chaix) J.F.…”

“…The soils were classified as Dystric Cambisol at two sites, as Entic Podzol at one site, and as Haplic Podzol at the most elevated site. Grab soil samples were taken from all soil horizons to measure basic soil properties (Borůvka et al, 2009) and to evaluate adsorption isotherms for Al and SO 4 2-. Undisturbed 100-cm 3 soil samples were taken from soil horizons, which were thick enough to insure soil material homogeneity (e.g.…”

Abstract:The aim of this study was to assess the impact of different vegetation on the distribution of rainfall (due to throughfall and stemflow), water regime, and Al and SO 4 2-leaching from forest soils. The water flow and Al and SO 4 2-transport were modeled using HYDRUS-1D. The study was performed at two elevation transects on the Paličník and Smědava Mountain in Jizera mountains. Podzols and Cambisols were prevailing soil units in this area. It was shown that the effect of the precipitation redistribution on water regime was considerable in the beech forest, while it was almost negligible in the spruce forest. Redistribution of precipitation under trees caused runoff (in one case), increased water discharge through the soil profile bottom, reduction of water storage in the soil, and thus reduction of root water uptake. Simulated Al leaching from the soil profile was determined mainly by the initial Al content in the soil profile bottom. Leaching of SO 4 2-was mainly determined by its initial content in the soil and to a lesser extent by redistributed precipitation and SO 4 2-deposition.

“…As has been documented on the example of the Jizerské hory Mts., soil pH decreasing, lowering of base saturation, Al mobilization, depletion of base cations, poor quality humus material, decelerating of decomposition process, accumulation of raw organic material, and many other belong to the main symptoms of this degradation process (e.g. Mládková et al 2004;Borůvka et al 2009). Moreover, rainfall redistribution together with prevailing spruce monoculture (Tejnecký et al 2013) have also largely contributed to soil acidification in this area.…”

Modelling the impact of acid deposition on forest soils in North Bohemian Mountains with two dynamic models: the Very Simple Dynamic Model (VSD) and the Model of Acidification of Groundwater in Catchments (MAGIC)

Vašát R., Pavlů L., Borůvka L., Tejnecký V., Nikodem A. (2015): Modelling the impact of acid deposition on forest soils in North Bohemian Mountains with two dynamic models: the Very Simple Dynamic Model (VSD) and the Model of Acidification of Groundwater in Catchments (MAGIC). Soil & Water Res., 10: 10-18.Enormous acid deposition that culminated in the 1970s contributed largely to accelerate the process of acidification of soils in northern Bohemia. As a consequence a wide forest decline occurred shortly afterwards. In this paper we present a long-term soil acidification modelling with two dynamic models (Model of Acidification of Groundwater in Catchments and Very Simple Dynamic Model) to describe history, make successive prediction, and assess possibility of recovery of the ecosystem. Focused on eight soil acidification indicators we found a strong rise of the soil acidification status in 1970s, when emission load culminated, and a large decrease after the year 2000 (after flue gas desulfurization). We further revealed slight differences, but general similarity, for both dynamic models. The results indicate that the impact of historic massive pollution will not probably be eliminated in the future by the year 2100.

Ca/Al ratio in Norway spruce fine roots on monitoring plots in the Czech Republic

2014

View full text Add to dashboard Cite

This article is focused on the evaluation of the Al/Ca ratio in fine roots of Norway spruce on the plots belonging to the ICP Forests monitoring programme in the Czech Republic. In total 122 fine root samples were collected from twenty plots from two soil layers of 0-10 and 10-20 cm and then analysed. The mean Ca/Al molar ratio in the fine roots from the 0-10 cm topsoil layer is higher than in the lower 10-20 cm soil layer, which corresponds to the distribution of fine roots -on average 80% of fine roots were found in the topsoil. 6% of the samples in the lower soil layer strongly indicate aluminium stress (Ca/Al < 0.1) and 30% of the samples may demonstrate the adverse effects of aluminium (< 0.2). On the other hand, no relationship was found between the Ca/Al ratio in the fine roots and the fine root biomass and vitality or crown condition. These results suggest that the potential aluminium toxicity is not the driving factor of the crown condition in Norway spruce and the Ca/Al ratio itself does not pose a risk to forest health in the region.
