“…Consequently, poplar SRC should be considered and managed as a system closer to agriculture than to silviculture. The importance of N in promoting poplar tree nutrition, growth and biomass yield has often been demonstrated in different site conditions and management options (Czapowskyj & Safford 1993, Heilman & Xie 1993, Brown & van den Driessche 2005, Coyle & Coleman 2005, Bilodeau-Gauthie et al 2011. In this study, we obtained high values of N removal in the woody biomass harvested in the first and second biennial cycles (Fig.…”

“…After two growing periods, it was ascertained that yields of banded trees were superior to broadcasted trees. Therefore we can assume that, in addition to the type of fertiliser, the form of application can additionally improve the fertiliser use effi ciency, which is also suggested by Brown & van den Driessche (2005) and Vetterlein et al (1999a). In analogy to the results of Ntayombya & Gordon (1995), black locust seedlings performed well under PK fertilised conditions, even without any mineral nitrogen donations and under initial soil conditions.…”

. Impact of P fertilisation on the growth performance of black locust (Robinia pseudoacacia L.) in a lignite post-mining area in Germany. Ann. For. Res. 58(1): 39-54.Abstract. Due to its ability to grow on marginal sites black locust (Robinia pseudoacacia L.) has been widely planted as a short rotation coppice (SRC) system that produce a renewable biomass feedstock in several post-mining areas of East Germany. However, as most of these sites are still in an initial stage of reclamation with low humus and nutrient contents, phosphorous can play a significant role as a plant limiting factor, because legumes require more P than other plants for their development. In April 2011, two experiments were conducted to evaluate the influence of higher rates and different applications of phosphorus fertiliser on the nutrition, survival, and biomass production of two different-aged black locust SRC plantations on the post lignite-mining site "Welzow-Süd", situated in NE Germany. Treatments were applied as triple superphosphate (30, 60 and 120 kg P ha -1 ) and PK fertiliser (60 kg P ha -1 ) through broadcasting or banding on recently harvested or planted trees, respectively. Soil, leaf and woody biomass data were analysed utilising the Mann-Whitney U test and the Spearman correlation coefficient (rS). Following two growing seasons, it was observed that the total dry weight yields of the black locust seedlings were increased strongly by up to 8 times when compared to the control group, particularly when TSP was applied through banding. P fertilisation, however, did not affect the biomass yield of six-year-old black locust trees, but P concentration in leaves among treatments of both sites was still significantly increased and sufficient from a quantity upwards of 60 kg P ha -1 . Taken together, a comparably moderate amount of P fertiliser (60 kg ha -1 ) had a strong impact on P uptake and growth performance in the examined black locust seedlings, which reveals a high potential to improve the current fertilisation practices for SRC black locust plantations grown on our research site.

“…There has also been reports on the benefits of combining N and P in other, possibly more nutrient-deficient stands (Blevins et al, 2006), notably some aspen (P. tremuloides) plantations in Western Canada (van den Driessche et al, 2005) and cottonwood clones in Washington State, USA (DeBell et al, 1990). In a study that combined competition control and fertilization, Borders et al (2004) observed increased growth due to competition control in the early years, while fertilization had lasting effects on growth enhancement.…”

a b s t r a c tThe silviculture of hybrid poplars and other fast-growing tree species is a promising solution to reduce the pressure on natural forests while maintaining wood supplies to industries. However, hybrid poplars are very sensitive to competing vegetation and to inadequate soil conditions and fertility. Possible management tools include mechanical site preparation (MSP), vegetation control (VC), and fertilization. Experimental plantations of hybrid poplars (one clone, Populus balsamea × Populus maximowiczii) were established at eight formerly forested sites on acidic soil in the southern boreal forest of Quebec, Canada. The objective was to test the response of hybrid poplars to the interaction of several silvicultural tools, which has been rarely done. Four MSP treatments (in decreasing order of intensity: mounding, harrowing, heavy disk trenching, light disk trenching) and a control (unprepared) were all combined with four different frequencies of plant competition control by brushing (from never up to once a year). Fertilization with N or N + P was also tested in three selected MSP treatments. After five years, hybrid poplar tree growth among MSP treatments increased in the following order: unprepared < light disk trenching < heavy disk trenching < harrowing < mounding. MSP was also essential in favouring early tree survival, as illustrated by mortality rates of over 20% in unprepared plots and below 5% in all other MSP treatments. The effect of competition control on hybrid poplar growth was greatest in the less intensive MSP treatments, where competing vegetation was the most abundant. On the contrary, fertilization effect was significant only in the most intensive MSP (mounding). Moreover, neither fertilization nor VC could compensate for inadequate soil preparation. Of all the silvicultural treatments tested, mounding provided the best tree growth despite a nitrogen and carbon impoverished surface soil.
