“…In general, nutrient use efficiency in plants decrease with increasing soil fertility (Vitousek et al 1995, Broeckx et al 2014. Our results of the second year agree with this finding, when a higher WNUE was observed for poplar clones grown on shallow soil, but not with the results of the third year of this study.…”

“…A trade-off between NUE and water use efficiency (WUE) within species has been demonstrated in many studies (Field et al 1983, Lajtha & Whitford 1989, Patterson et al 1997, Sadras & Rodriguez 2010, Broeckx et al 2014). For example, Broeckx et al (2014) showed that a trade-off between intrinsic water use efficiency and photosynthetic N use efficiency existed among six poplar genotypes, but only when soil water availability was restricted.…”

“…For example, Broeckx et al (2014) showed that a trade-off between intrinsic water use efficiency and photosynthetic N use efficiency existed among six poplar genotypes, but only when soil water availability was restricted. Considering that drought stress was likely an important limiting factor on shallow soil, the variation in WNUE or NUE might be related to differences in water availability among different years.…”

Growth performance and nitrogen use efficiency of two Populus hybrid clones (P. nigra × P. maximowiczii and P. trichocarpa × P. maximowiczii) in relation to soil depth in a young plantation Dejuan Euring It is a challenge to produce woody crops on marginal land. The goal of this study was to examine growth responses and nitrogen use efficiency of different poplar species on shallow soil. Typical biomass poplar clones of Max1 (P. nigra × P. maximowiczii) and H275 (P. trichocarpa × P. maximowiczii) were planted on a marginal site where a gradient in soil depth was present. The growth, biomass production, and nitrogen uptake rate as well as nitrogen use efficiency of Max1 and H275 were determined for three consecutive years. Both poplar clones showed decreased growth and biomass production in the shallow soil. Max1 showed better adaptation to shallow soil with higher survival rate and more biomass production than H275. Max1 had lower nitrogen use efficiency on shallow soil than H275. The results suggest that higher nitrogen uptake of poplar species might be an important adaptation to maintain productivity under unfavorable soil conditions. Keywords: Biomass, Nitrogen Use Efficiency, Poplar, Shallow Soil IntroductionWoody biomass is considered as a sustainable alternative source of energy for fossil fuels (Pleguezuelo et al. 2015). Short rotation woody crops such as poplar trees (Populus spp.) are well suited for woody biomass production because they are highly productive and can be managed using agronomic techniques (Kauter et al. 2003). To avoid competition for fertile land with food production, poplar plantations are expected to be established on marginal land which is less suitable for agriculture because of limited water and nutrient availability (Shortall 2013). Since the productivity of a poplar plantation depends on the proper selection of genotypes (Zalesny et al. 2011), research is needed to identify poplar cultivars with high survival rates, high biomass productivity and high disease resistance for cultivation on marginal soil ).Shallow soil with limited rooting depth, low drainage and high stone content are typical features of marginal land (Jiang et al. 2014). Rooting depth is an important determinant for the successful establishment and production of woody biomass (Burgess et al. 2015). N storage and cycling are vital processes for growth, adaptation and productivity of poplar trees (Millard & Grelet 2010). N storage and remobilization are particularly important to meet the N demand of forest trees for continuous growth (Rennenberg et al. 2010). Poplar species differ in the way they take up and assimilate N (Luo et al. 2013, Gan et al. 2015, which may impact their competitive ability for soil nutrients and resistance to environmental stresses (Castro-Rodríguez et al. 2015, Molina-Rueda & Kirby 2015. Several studies have focused on identifying and quantifying the best management practices to successfully establish hybrid poplar plantations under different nitrogen regimes (Lee & Jose 2003, Euring et al....

“…Superior growth of poplar SRC is, however, not always associated with different allocation patterns, as shown for different hybrids and P. deltoides clones (Dowell et al 2009). Genotypic variation in photosynthesis is related to leaf structural (e.g., leaf mass per area, LMA) and biochemical (e.g., leaf N concentration) parameters (Casella & Ceulemans 2002, Xu & Baldocchi 2003, Broeckx et al 2014b). Significant genotypic differences have already been documented for LMA, leaf N concentration, maximum carboxylation rate (Vc max) and other photosynthetic parameters (Casella & Ceulemans 2002, Verlinden et al 2013, Broeckx et al 2012, 2014b.…”

© iForest -Biogeosciences and Forestry IntroductionEnergy security and greenhouse gas emission reductions are major challenges to meet the global energy demand and to mitigate climate change (IPCC 2014). In the light of these global concerns bioenergy could play a crucial role to achieve the EU's energy and climate targets (European Council 2009). The cultivation of lignocellulosic biomass, mostly poplar and willow in short rotation coppice (SRC) systems, has a high potential for the production of renewable electricity and the generation of "green" heat (Fischer et al. 2010). Despite the long-term experience with the commercial production in northern Europe (Rosenqvist et al. 2000, Langeveld et al. 2012, the implementation of SRC as a renewable energy crop is limited in European agriculture (AEBIOM 2010, Dimitriou et al. 2011, Don et al. 2011.Productivity is determined by light interception and by the efficiency of converting the intercepted radiation into biomass, i.e., the radiation use efficiency (RUE), as reported for both herbaceous (Sinclair & Horie 1989) and woody (tree) species (Cannell et al. 1988, Medlyn 1998. The crop's capacity to intercept radiation is determined by its photosynthetic area, generally assessed via the leaf area index (LAI), which is linearly related to the biomass production in poplar and willow plantations (Larson & Isebrands 1972, Cannell et al. 1988, Taylor et al. 2001a. In SRC systems, faster canopy closure and increased growth rates of sprouts from an established root system result in enhanced productivity of coppiced versus noncoppiced tree stands . Substantial genotypic variation exists in aboveground woody biomass productivity (AGWB) of SRC cultures in poplar (Ceulemans & Deraedt 1999, Dillen et al. 2011, Paris et al. 2011, Benetka et al. 2014). Variation in AGWB has been explained by variation in light interception, in biomass allocation, in leaf physiological factors related to RUE or in a combination of the aforementioned (Cannell et al. 1988, Green et al. 2001, Tharakan et al. 2008, suggesting inconclusive results on the relative importance of productivity determining factors in SRC. The quantification of genetic diversity and of genetic control contributes to future tree improvement and to yield maximization efforts towards sustainable bioenergy cultivation.In the present study, we analyzed the leaf area development, light interception and RUE of 12 poplar genotypes in a high-density SRC culture, before and after the first coppice of an experimental plantation. Assessment of LAI and woody biomass productivity was performed in a single versus a multi-stem culture, to analyze the effect of coppicing. We hypothesized significant genotypic, parentage and provenance variation in LAI, in leaf area duration (LAD), in RUE, in intercepted radiation (Iint) and AGWB. The objectives of this study were: (i) to determine the main differences between the first (R1) and the second rotation (R2) in the above mentioned parameters and in their relationships, i.e., before and after coppice,...

“…The change in physiological condition can be a result of nutritional imbalance in other necessary for photosynthesis and growth nutrients and provoked osmotic stress in soil caused by the high level of nutrients itself (Elliott and White 1994). The former affects the photosynthetic nutrient use efficiency (Thomas et al 1994), whilst the latter provides to limitation of stomata opening, and thus, photosynthesis of trees decreases (Broeckx et al 2014). The stomatal closure limits the CO 2 uptake.…”

Key message The high concentration of N and K caused a weakening of physiological conditions of the trees. Application of N, P and K from starch effluent is not a suitable method of waste management. Abstract Since 1984, potato starch effluent has been applied to trees in the Iława Forest Inspectorate to promote the biological utilization of this waste product containing high amounts of nitrogen (N), phosphorus (P) and potassium (K). We examined the tree rings of Scots pine (Pinus sylvestris L.) to study the effect of intensive fertilization on tree rings. A total of 120 samples were taken from three sites representing a fertilized and unfertilized area and trees growing at a control site, outside the forest waste water system. We found that February and March temperature influenced the growth of tree rings. We used multiple regression to investigate the influence of N, P and K concentration, the amount of waste water and February and March temperature upon tree growth. Akaike information criterion (AIC) model selection was applied to choose the most influential factors upon growth, and additional multiple regression analyses were performed for two subsets of variables. Trees growing on the unfertilized site responded positively to N content and negatively to P content. For the fertilized site, the high concentration of N and K together with decreasing volume of waste water caused a growth decline. Trees from fertilized area also showed a decrease in their photosynthetic efficiency.
