“…In our study, N and S additions decreased the soil C/N ratio and increased the soil N/P ratio (Fig. 1d and f), which is consistent with the findings reported in other studies (Huang et al, 2018;van Dijk et al, 2012). Changes in soil stoichiometric ratios can alter nutrient cycles in plant-soil systems (Peng et al, 2019;Sardans and Peñuelas, 2015), which may affect tree health and forest services (Aherne and Posch, 2013;Yuan and Chen, 2015).…”

“…Soil stoichiometric ratios have been widely used to study the responses of soil ecosystem nutrient balances and soil carbon (C), N, and phosphorus (P) biogeochemical cycles to the inputs of external nutrient elements (Sardans and Peñuelas, 2012;van Dijk et al, 2012). External N addition generally increases the availability of soil N (Magill et al, 2004;Michopoulos et al, 2004).…”

“…Changes in plant N:K ratios caused by N deposition have been observed in European Calluna vulgaris heathlands (Britton et al 2008;Rowe et al 2008). Sulphur (S) deposition is frequently associated with N deposition (Van Dijk et al 2012;Aherne & Posch 2013), changing soil and plant elemental composition and stoichiometry (Robroek et al 2009;Van Dijk et al 2012). This further affects the demographic, phenotypically plastic and adaptive responses of plants (Carnicer et al 2015), so S and N deposition are usually studied together to analyse the impacts of human-driven global change on the plant-soil system.…”

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.

Nitrogen (N) and phosphorus (P) are the most limiting nutrients in natural freshwater wetlands. Flooded marshes dominate in the freshwater wetlands of the Lower Paraná River floodplain (Argentina). The leaf N and P concentration and the N:P ratios were assessed as a first approach to evaluate the nature of nutrient limitation. A total of 96 sites and 131 dominant plant populations (belonging to 50 herbaceous macrophyte species) were sampled in medium hydrometric level conditions. The interspecific variability of leaf nutrients was higher than the intraspecific variability. Foliar N ranged from 0.5% to 5.3%, while foliar P ranged from 0.1% to 0.5%. Leaf N:P was 9.3 ± 4.3 (mean ± standard deviation), suggesting N-limitation for most of the plant populations –under the assumption of the validity of the critical N:P thresholds previously proposed (N:P < 10 for N limitation, N:P > 20 for P limitation). Neither the leaf nutrients nor the N:P were affected by the flooding frequency, hydrometric water level, or wetland landscape unit/subunit location. The species identity accounted for most of the leaf nutrient and N:P variability, followed by the sampling date for P and N:P levels. This study provides a baseline on the nature of nutrient limitation, mainly by N, in plants of the Lower Paraná River floodplain. Future surveys or experiments could address the variations of leaf nutrients and nutrient limitation in contrasting hydrological conditions.
