Since 1994, the nutritional status and the air pollution load have been evaluated on 20 research plots, located in young Norway spruce stands in the ridge area of the Krušné hory Mts. The most recent acute damage to the spruce stands, in the winter of 1995/96, was connected with a long-lasting inversion situation in the eastern area of the Krušné hory Mts. Today, the health status of the spruce stands, expressed in terms of the crown defoliation, has recovered and is comparable to that found in other regions of the Czech Republic. The sulphur and fluorine content of the needles has decreased significantly. The long-term negative effect of acid deposition that contributes to the degradation of forest soils remains an important part of stressors acting on forest ecosystems in the region. In recent years, nitrogen and sulphur concentrations in the needles have increased slightly again. A long-term tendency towards a decrease in the phosphorus, calcium and potassium content of the needles was detected.

“…Low foliar P concentrations and high N/P ratios are in turn related to reduced growth in forest stands (Braun et al 2010;Prietzel and Stetter 2010;Trichet et al 2009;Wardle et al 2004). Reduced forest growth might be the consequence of reduced leaf size and total leaf area, which was found to be the response to low P supply in white birch (Danyagari and Dang 2014).…”

“…Increased forest soil acidification, atmospheric N deposition, and climate change (increasing temperature and CO 2 levels) have been shown to affect P nutrition of forest trees (Aber 1992;Duquesnay et al 2000;Thomas 2006, 2008;Prietzel and Stetter 2010). Low foliar P concentrations and high N/P ratios are in turn related to reduced growth in forest stands (Braun et al 2010;Prietzel and Stetter 2010;Trichet et al 2009;Wardle et al 2004).…”

On 62 % of the plots, the nitrogen/phosphorus ratio was above 18.9, which is considered to be disharmonious for beech. In addition, foliar phosphorus concentrations were significantly decreasing by, on average, 13 % from 1.31 to 1.14 mg g −1 in Europe (p<0.001). & Conclusion Our results show that phosphorus nutrition of beech is impaired in Europe. Possible drivers of this development might be high atmospheric nitrogen deposition and climate change. Continued decrease in foliar phosphorus concentrations, eventually attaining phosphorus deficiency levels,

“…). Some of these data, however, were obtained in the 1960s, before the dramatic increase in N deposition due to human activities (Prietzel & Stetter ). The considerable climatic gradients (mean annual precipitation (MAP), 335–1768 mm year −1 ; mean annual temperature (MAT), ‐2·1–16·1 °C) and the variation in N deposition (0·55–27·0 kg N ha −1 ) across the distribution of P. sylvestris make this species an adequate model to test the links between these variables and their interactions, growth and the soil–plant stoichiometric response.…”

1. This study investigated the factors underlying the variability of needle and soil elemental composition and stoichiometry and their relationships with growth in Pinus sylvestris forests throughout the species' distribution in Europe by analysing data from 2245 forest stands. 2. Needle N concentrations and N:P ratios were positively correlated with total atmospheric N deposition, whereas needle P concentrations were negatively correlated. These relationships were especially pronounced at sites where high levels of N deposition coincided with both higher mean annual temperature and higher mean annual precipitation. Trends towards foliar P deficiency were thus more marked when high N deposition coincided with climatic conditions favourable to plant production. 3. Atmospheric N deposition was positively correlated with soil solution NO À 3 , SO 2À 4 , K + , P and Ca 2+ concentrations, the soil solution NO À 3 :P ratio, total soil N and the total soil N:Olsen P ratio and was negatively correlated with soil Olsen P concentration. 4. Despite these nutrient imbalances, during the period studied (1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006), N deposition was positively related with Pinus sylvestris absolute basal diameter (BD) growth, although only accounting for the 10% of the total variance. However, neither N deposition nor needle N concentration was related with relative annual BD growth. In contrast, needle P concentration was positively related with both absolute and relative annual BD growth. 5. These results thus indicate a tendency of European P. sylvestris forests to store N in trees and soil in response to N deposition and unveil a trend towards increased nutrient losses in run-off as a consequence of higher soil solution N concentrations. Overall, the data show increasing ecosystem nutrient imbalances with increasingly limiting roles of P and other nutrients such as K in European P. sylvestris forests, especially in the centre of their distribution where higher levels of N deposition are observed. Thus, although the data show that N deposition has had an overall positive effect on P. sylvestris growth, the effect of continuous N deposition, associated with decreasing P and K and increasing N:P in leaves and in soil, may in the future become detrimental for the growth and competitive ability of P. sylvestris trees.
