ABSTRACT:We evaluated the potential of crushed amphibolite and artificial slow-release N-P-K-Mg fertiliser to stimulate the survival, growth and nutrition of Norway spruce planted on an acidified air-polluted mountain site. Control plots and treatments with slow-release fertiliser (SRF) and amphibolite (AMT) were installed. In the SRF, forty grams of tabletted amendment were applied in the close vicinity of the trees. In the AMT, two kilograms of amendment were incorporated into the soil inside the planting hole of each tree at planting. The SRF application resulted in a significant growth stimulation of spruces. The growth stimulation by amphibolite was perceptible but not significant; this amendment, however, significantly reduced mortality. None of the amendments induced marked changes in foliar nutrient concentrations.

“…The catchment (1.9 km 2 , 780-870 m a.s.l. ; Fottova and Skorepova 1998;Fottova 2003;Kram et al 2004) is underlain by biotitic granite and contains a Sphagnum-dominated peat bog (0.5 km 2 ). Soils outside of the bog are Orthic Podzols.…”

Isotope Systematics of Sulfate-oxygen and Sulfate-sulfur in Six European Peatlands

et al. 2005

Oxygen (O) and sulfur (S) isotope systematics in bog water sulfates were determined for six Sphagnum dominated wetlands located in the British Isles and the Czech Republic, Central Europe. Comparison of a polluted and unpolluted site showed that 4 times higher atmospheric S inputs led to 3 times higher bog water sulfate concentrations and substrate S concentrations, 3 times increased ranges of substrate S concentrations, and 3 times increased ranges of d 34 S values. Sites with elevated atmospheric S inputs exhibited greater geochemical variability in wetland S species. Sulfate O-S isotope composition of bog pore water at a depth of 40 cm below surface differed from that of surface bog water, indicating that dissimilatory bacterial sulfate reduction, a process known to discriminate against the heavier isotopes 18 O and 34 S, occurred in surface peat layers. While bacterial sulfate reduction remained to be one of the main isotope-selective processes for sulfate in peat, it could not fully explain the O-S isotope systematics of peat waters. The 'residual' sulfate was not simultaneously enriched in the heavier isotopes 18 O and 34 S. Mixing of residual sulfate following bacterial sulfate reduction with the product of S 2À reoxidation, cleavage of esters, and isotope exchange reactions may have contributed to the decoupling of the d 34 S SO4 and d 18 O SO4 values. Large within-site differences in d 18 O SO4 and d 34 S SO4 (up to 13 and 15&, respectively) indicated little communication between the 0 and 40 cm peat depth at some sites. Extremely high d 18 O SO4 and d 34 S SO4 values found in several peat bog water samples from Connemara (Ireland), Thorne Moors (England) and Ocean (Czech Republic) were not seen in streams draining the wetlands. Direct runoff of atmogenic sulfate constituted a significant portion of the bog outflow. At the wetland scale, zones of dissimilatory bacterial sulfate reduction form pockets whose lateral hydrological fluxes are small.

“…The GEOMON network was primarily established for geochemical monitoring related to the impact of acidic atmospheric deposition that strongly affected Central Europe in late 1980s. The catchment hydrology of GEOMON sites has been investigated since 1994 (Fottová & Skořepová 1998;Benčoková et al 2011a). Catchments were selected in order to represent hydrological patterns of different areas of the Czech Republic (Figure 1).…”

Lamačová A., Hruška J., Krám P., Stuchlík E., Farda A., Chuman T., Fottová D. (2014): Runoff trends analysis and future projections of hydrological patterns in small forested catchments. Soil & Water Res., 9: 169-181.The aims of the present study were (i) to evaluate trends in runoff from small forested catchments of the GEOMON (GEOchemical MONitoring) network during the period 1994-2011, and (ii) to estimate the impact of anticipated climate change projected by ALADIN-Climate/CZ regional climate model coupled to ARPEGE-Climate global circulation model and forced with IPCC SRES A1B emission scenario on flow patterns in the periods 2021-2050 and 2071-2100. There were no general patterns found indicating either significant increases or decreases in runoff on either seasonal or annual levels across the investigated catchments within 1994-2011. Annual runoff is projected to decrease by 15% (2021-2050) and 35% (2071-2100) with a significant decrease in summer months and a slight increase in winter months as a result of expected climate change as simulated by the selected climate model.
