“…This is in accordance with the findings of some earlier national case studies carried out in Western and Central Europe (Braun et al 2010;Jonard et al 2009). Even though plots in Eastern Europe are underrepresented in this study, it can be stated that foliar P concentrations decreased also in these countries ( Fig.…”

“…As already suggested by Ewald (2000) and Braun et al (2010), P deficiency might lead to reduced growth and vitality of European beech forests. In addition, the susceptibility of trees to parasite infestation might be increased due to nutrient imbalances, including P (Flückiger and Braun 2003).…”

“…The improved N nutrition initially led to increased forest growth (Braun et al 1999;Högberg et al 2006;Spiecker 1999), but might also have provoked nutrient imbalances (Aber et al 1998) including P deficiency (Flückiger and Braun 1998;Mellert et al 2004;Mohren et al 1986). In N-saturated forests, a shift from N to P limitation of forest growth has already been observed (Braun et al 2010;Gradowski and Thomas 2006;Peñuelas et al 2013) and may be due to several processes. Firstly, excess N in soils is known to inhibit mycorrhizal growth (Nilsson and Wallander 2003) and to result in a shift in the microbial community structure (Waldrop et al 2004).…”

“…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).…”

“…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). P deficiencies, decreasing foliar P levels, or high N/P ratios have been reported for beech forests in Switzerland (Braun et al 2010), France, Belgium, and Luxemburg (Jonard et al 2009). However, many questions concerning forest P nutrition are still unexplained.…”

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,

Experimental evidence of nutrient limitations on primary productivity in Afrotropical forests is rare and globally underrepresented yet are crucial for understanding constraints to terrestrial carbon uptake. In an ecosystem‐scale nutrient manipulation experiment, we assessed the early responses of tree growth rates among different tree sizes, taxonomic species, and at a community level in a humid tropical forest in Uganda. Following a full factorial design, we established 32 (eight treatments × four replicates) experimental plots of 40 × 40 m each. We added nitrogen (N), phosphorus (P), potassium (K), their combinations (NP, NK, PK, and NPK), and control at the rates of 125 kg N ha−1 year−1, 50 kg P ha−1 year−1 and 50 kg K ha−1 year−1, split into four equal applications, and measured stem growth of more than 15,000 trees with diameter at breast height (dbh) ≥1 cm. After 2 years, the response of tree stem growth to nutrient additions was dependent on tree sizes, species and leaf habit but not community wide. First, tree stem growth increased under N additions, primarily among medium‐sized trees (10–30 cm dbh), and in trees of Lasiodiscus mildbraedii in the second year of the experiment. Second, K limitation was evident in semi‐deciduous trees, which increased stem growth by 46% in +K than –K treatments, following a strong, prolonged dry season during the first year of the experiment. This highlights the key role of K in stomatal regulation and maintenance of water balance in trees, particularly under water‐stressed conditions. Third, the role of P in promoting tree growth and carbon accumulation rates in this forest on highly weathered soils was rather not pronounced; nonetheless, mortality among saplings (1–5 cm dbh) was reduced by 30% in +P than in –P treatments. Although stem growth responses to nutrient interaction effects were positive or negative (likely depending on nutrient combinations and climate variability), our results underscore the fact that, in a highly diverse forest ecosystem, multiple nutrients and not one single nutrient regulate tree growth and aboveground carbon uptake due to varying nutrient requirements and acquisition strategies of different tree sizes, species, and leaf habits.
