“…The most intensive microbial transformations occur in the uppermost organic-rich soil horizons [ 9 , 10 ]. Their chemistry usually reflects changes in the composition of atmospheric deposition [ 11 ], vegetation type [ 12 ], and ecosystem disturbances, associated with tree harvesting or natural forest dieback [ 6 , 13 , 14 ]. Important soil parameters sensitive to ecosystem disturbances include the availability of inorganic N forms and rate of N mineralization processes [ 7 , 15 – 17 ].…”

Mountain forests in National park Bohemian Forest (Czech Republic) were affected by bark beetle attack and windthrows in 2004–2008, followed by an extensive tree dieback. We evaluated changes in the biochemistry of the uppermost soil horizons with the emphasis on carbon (C) and nitrogen (N) cycling in a near-natural spruce (Picea abies) mountain forest after the forest dieback, and compared it with an undisturbed control plot of similar age, climate, elevation, deposition, N-saturation level, and land use history. We hypothesised that the high litter input after forest dieback at the disturbed plot and its consequent decomposition might influence the availability of C for microorganisms, and consequently, N transformations in the soil. The concentrations of dissolved organic C (DOC) and N (DON) in soil water extracts rapidly increased at the disturbed plot for 3 yeas and then continually decreased. Net ammonification exhibited a similar trend as DOC and DON, indicating elevated mineralization. Despite the high ammonium concentrations found after the forest dieback (an increase from 0.5 mmol kg-1 to 2–3 mmol kg-1), net nitrification was stable and low during these 3 years. After the DOC depletion and decrease in microbial biomass 5 years after the forest dieback, net nitrification started to rise, and nitrate concentrations increased from 0.2–1 mmol kg-1 to 2–3 mmol kg-1. Our results emphasize the key role of the availability of organic C in microbial N transformations, which probably promoted microbial heterotrophic activity at the expense of slow-growing nitrifiers.

Immission-load-related dynamics of S-SO₄ ²⁻ in precipitation and in lysimetric solutions penetrating through beech ecosystems

Kukla, J., Bublinec, E., Schieber, B., Kellerová, D., Bičárová S., Janík, R., 2017. Immission-load-related dynamics of S-SO 4 2-in precipitation and in lysimetric solutions penetrating through beech ecosystems. Folia Oecologica, 44: 96-106.The paper presents the results of a 23-year study of sulphate sulphur dynamics in beech ecosystems exposed to different immission loads. . The S-SO 4 -2 amounts penetrating the individual soil layers in the Kremnické vrchy Mts were as follows: in case of surface humus on clear-cut area 459 kg ha -1 (20.9 kg ha -1 per year), in beech forest 433 kg ha -1 (19.7 kg ha -1 per year); below 10 cm organo-mineral layer of the mentioned plots penetrated 169-171 kg ha -1 (7.7-7.8 kg ha -1 per year), and below 25 cm mineral layer 155-255 kg ha -1 (7.1-11.6 kg ha -1 per year) -a higher amount was found on clear-cut area with an episodic lateral flow of soil solutions. In beech forest of the Štiavnické vrchy Mts penetrated below surface humus 424 kg ha -1 S-SO 4 2-(18.9 kg ha -1 per year), below 10 cm mineral layer 458 kg ha -1 S-SO 4 2-(19.9 kg ha -1 per year), and below 25 cm mineral layer as much as 599 kg ha -1 S-SO 4 2-(26.0 kg ha -1 per year). This fact was caused by frequent lateral flow of soil solutions. The results indicate that the assumption about lower immission load of the beech ecosystem in the Kremnické vrchy Mts is wrong, at least in the case of S-SO 4 2-. The testing has revealed that the studied beech ecosystems differ very significantly in sulphur amounts penetrating under 0.10 m and 0.25 m. The inter-annual differences were insignificant.

“…The differences in the mineralogical composition of the selected soils are minimal. The soils have been detailedly described previously (Pavlů et al 2007;Tejnecký et al 2010Tejnecký et al , 2013. Half of the samples were taken under beech stands (b samples) and half under spruce stands (s samples).…”

Vytopilová M., Tejnecký V., Borůvka L., Drábek O. (2015): Sorption of heavy metals in organic horizons of acid forest soils at low added concentrations. Soil & Water Res., 10: 1-9.The individual adsorption/desorption of Cu, Pb, and Zn in six soil samples taken from organic horizons of acid forest soils is studied in batch experiments. These three metals were chosen because of the varying extent of their sorption to the soil organic matter. The initial concentration range for all metals is 0-200 mg/l. 0.01 mol/l Ca(NO 3 ) 2 was used as the background electrolyte. Soil samples were taken at random locations throughout a relatively small area and are characterized by small differences in mineralogical composition. Organic matter content and pH of soils are considered as the key factors causing differences in sorption/desorption behaviour of selected metals. In general, the sorption of all the three metals increased with a combination of higher pH value and increasing organic matter content. Anyway, the extent of the influence of these two characteristics on sorption behaviour of metals is different, for desorption significant differences were not determined. Copper sorption seems to reflect mainly the differences in organic matter content in addition to the differences in pH. The average amount of sorbed Pb was approximately 90%, Cu sorption averaged 60%, and that of Zn 30%. Desorption of Pb into 0.01 mol/l Ca(NO 3 ) 2 remained at approximately 4%, for Zn at 30%, and desorption of Cu reached up to 13% of the amount adsorbed. All the studied soils proved effective at immobilizing lead and copper, but zinc was relatively highly released from these soils, even when the sorbed amount was minimal. Different vegetational background of these samples (either beech or spruce forests) does not significantly influence the sorption extent of these metals as the lower pH of samples taken under spruce stands is probably compensated by higher organic matter content in these samples. The experimental data are fitted by the Freundlich equation and the parameters of this equation together with the adsorption and desorption efficiency are used for comparison of the behaviour of all the three metals among the six soils.
