“…N saturation (defined as N availability in excess of biological demand) has been cited as a contributor to forest mortality (Aber et al, 1989;Magill et al, 2000Magill et al, , 2004. High levels of forest floor N, relative to biological demand, can lead to foliar nutrient imbalance (Zoettl and Huettl, 1986;Cronan and Grigal, 1995), reduced red spruce cold tolerance (Sheppard, 1994;Schaberg et al, 2002), and increased freeze injury to foliage that in turn reduce carbohydrate reserves and increase the potential for secondary stressors that can cause tree mortality (DeHayes, 1992;Schaberg et al, 1997;Perkins et al, 2000). Other environmental stressors, such as drought (Johnson and Siccama, 1983;Driscoll et al, 2003) and aluminum toxicity in roots (Shortle and Smith, 1988), or nutrient leaching from the forest floor (Berg, 1986;Johnson et al, 1994;Adams, 1999) could act synergistically with N saturation to increase the potential for tree mortality on already pollutant-stressed forests.…”

In the early 1980s, nitrogen (N) deposition was first postulated as a cause of N saturation and spruce mortality across the northeastern US. In 1988, a series of high elevation spruce-fir forest N addition plots were established on Mt. Ascutney (southeastern) Vermont to test this hypothesis. The paired plots each received, in addition to ambient N deposition, 15.7 kg N ha-' (low N addition), 31.4 kg N ha-' (high N addition) or no N addition (control) from 1988 to 2002. Over the years, potential and annual in situ forest floor net N mineralization and net nitrification, foliar and forest floor elemental concentrations, and basal area growth by species were measured on each plot. Live basal area decreased by 18% on the low N addition plots, and by 40% on the high N addition plots between 1988 and 2002, while the control plots had a 9% increase in basal area over the same time period. Initially, none of the plots had measurable rates of in situ nitrification, but by 2002,21% of the mineralized N was being annually nitrified on the high N addition plots, compared to no net nitrification on the control plots. We also observed a significant increase in forest floor N concentration on the high N plots from 1988 to 2000. Reductions in live basal area, and increased net nitrification suggest that we induced late stage N saturation on the high N addition plots. The low N addition plots exhibited symptoms of mid-stage N saturation, with a smaller reduction in live basal area and net N mineralization, and a smaller increase in net nitrification compared to the high N addition plot values. Other correlations between forest floor and vegetation composition and function, and N saturation will be discussed in the paper.

“…Nutrient concentrations in different compartments of tree biomass are commonly used for evaluation of plant nutrient status, soil nutrient availability and as indicators of forest health [14,26,47,53]. Biomass and nutrient concentrations in different tree compartments are used for estimation of tree nutrient uptake and nutrient removal by harvest, and are thus crucial for understanding of nutrient circulation in forest ecosystems and in the assessment of the sustainability of forest management [23,50].…”

-Common European tree species (oak, ash, beech, birch, lime and spruce) planted in adjacent stands on six sites were compared in terms of macronutrient concentrations in foliar and stem wood (including bark) biomass. The nutrient concentrations in both biomass compartments were much more dependent on species than on site although soil conditions differed between the sites. Differences between species regarding stem wood nutrient concentrations only partly corresponded to the differences in species foliage. The concentrations in spruce were considerably lower than in deciduous species, except P in foliage, and Ca in both stem wood and foliar biomass. Differences were also observed between the deciduous species both regarding foliar and stem wood nutrient concentrations. The differences should be considered when modelling nutrient circulation in forest stands and when evaluating the long-term sustainability of forest management. nutrient / hardwood / Norway spruce / stemwood / foliage Résumé -Éléments minéraux dans le tronc et le feuillage : une étude comparative de six essences tempérées plantées sur les mêmes sites. Les essences européennes communes (chêne, frêne, hêtre, bouleau, tilleul et épicéa commun) plantées dans des parcelles adjacentes sur six sites ont été comparées en termes de concentrations en macro-éléments minéraux dans la biomasse foliaire et dans le tronc (écorce y compris). Ces concentrations dépendaient plus de l'espèce que du site, bien que les conditions de sol étaient différentes entre les sites. Les différences entre les espèces observées dans le bois de tige ne correspondaient que partiellement à celles observées dans le feuillage. L'épicéa commun était plus pauvre en éléments minéraux que les feuillus excepté concernant le P dans le feuillage, et le Ca dans le tronc ainsi que dans la biomasse foliaire. Des différences de concentrations minérales ont également été observées entre les espèces de feuillus dans le bois ainsi que dans le feuillage. Ces différences devraient être considérées pour la modélisation de la circulation des éléments minéraux dans les peuplements forestiers et dans l'évaluation des aménagements forestiers dans le cadre d'une gestion durable. nutriment / feuillu / épicéa commun / bois de tige / feuillage e

“…Thus, we can suppose that an increased danger of washing out nitrates from the whole soil profile mentioned, e.g. by (Zoettl, Huettl 1986), does not occur. Lower concentrations of nitrates NO 3 -were detected in throughfall (3.7 mg.l -1 ) during previous measurements (Klimo et al 1996), which currently slightly increased.…”

]; BC/Al = 11,4. Based on the results obtained, it is possible to notice effects of the stand species on the condition of the forest floor and its development. These effects were less favorable for the 34-year old spruce monoculture aged as compared to the 40-year old the beech monoculture (for the latter we found some positive, soil-improving effects) grown over a time period of two generations of unmixed spruce stands.Keywords: aluminum; forest floor; tree species composition; Drahanská vrchovina Upland; Czech RepublicAbbreviations:
