“…These temporal patterns confirm the trends previously observed (Duquesnay et al, 2000;Flückiger and Braun, 1998;Luyssaert et al 2004;Mellert et al, 2004;Thelin et al, 1998) and can be explained by the joint actions of several processes that influence tree nutrition in the long term: tree age, N and S deposition, harvesting and climate.…”

“…At present, large data sets on forest functioning are available in Europe since forest monitoring has started more than 20 years ago thanks to ICP forests and the European Commission. Based on data analyzed at national level, the temporal variation in foliar chemistry has already been described for several regions (Flückiger and Braun, 1998;Thelin et al, 1998;Luyssaert et al, 2004;2005). Generally, the temporal pattern is characterized by an increase in foliar N concentration and a decrease in foliar phosphorus (P), calcium (Ca), magnesium (Mg) and potassium (K) concentrations (Duquesnay et al, 2000;Flückiger and Braun, 1998;Luyssaert et al, 2004;Mellert et al, 2004;Thelin et al, 1998).…”

Abstract• Two decades after the launching of the monitoring program of forest ecosystems in Europe (ICP forests), a unique data set is now available regarding the foliar nutritional status of the main broadleaved species growing in much-diversified sites (soil, climate).• This study focuses on the foliar concentration time series (1993 to 2005) of the French (RENECO-FOR), Walloon and Luxemburg broad-leaved plots. The aim is to show long-term trends while taking the inter-plot and inter-annual variability into account.• Two kinds of statistical processing were used to analyze the data on foliar chemistry: principal component analysis (PCAs) and linear mixed models. In general, the main temporal trends reveal a decrease in the foliar P concentration and a decrease in the foliar Ca concentration, except for European beech on acid soils.• These temporal patterns confirm the trends previously observed and could be explained by the joint actions of several processes that influence tree nutrition in the long term: tree age, N and S deposition, harvesting and climate.

L'objectif est de mettre en évidence la tendance à long-terme tout en prenant en compte la variabilité inter-placette et inter-annuelle.• Deux types de traitements statistiques ont été utilisés pour analyser les données de nutrition foliaire : l'analyse en composantes principales (ACP) et les modèles linéaires mixtes. Globalement, la tendance principale est une diminution généralisée de la teneur foliaire en P and une diminution de la teneur foliaire en Ca, sauf en ce qui concerne le hêtre sur sols acides.• Ces tendances temporelles confirment celles déjà observées par le passé et pourraient être expliquées par l'action combinée de différents processus influençant la nutrition des arbres à long-terme (vieillissement, dépôts azotés et soufrés, exploitation, fructification).

“…However, there is still little information about the long-term effects of liming on the nutrient concentrations in the leaves, although this criterion is widely used for evaluation of the nutrient status, soil nutrient availability, and as an indicator of forest health [13]. In general, long-term studies on the nutrient status are rare [38]. A broader assessment of forest nutrition of forests in Europe was not started until the Level II programme in 1994 [29].…”

-From 1982 to 2004 the elemental concentrations of current, current+1, and current+2 year old needles of a mature spruce stand were investigated at the N-saturated, acidified, but healthy Höglwald site. The control was compared with a liming, experimental acid irrigation, acid irrigation + liming, normal irrigation, and normal irrigation + liming treatment. Liming was performed in 1984, and irrigation from [1984][1985][1986][1987][1988][1989][1990]. High year to year variations were found for most of the elements in all treatments, especially for K ("deficient" to "high"). Despite the N saturation of the ecosystem, needles showed no N-overfeeding of the trees. N, Mg, K, Fe concentrations showed no clear treatment effects. Twenty years after liming a lowered P availability is indicated, which was more pronounced in older needles. Ca concentrations increased after liming, while Al decreased. The elemental concentrations of the acid irrigated treatment did not differ significantly from the normal irrigated or control treatment.

-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
