“…Two growing seasons after establishment, their total aboveground biomass yield was very similar -between 15 and 20 t ha -1 of dry-matter per year, confirming the high potential of these two species under Quebec's agro-ecological conditions [28]. A subsequent trial aimed at evaluating these two species comparatively with S. petiolaris Smith; both the first-tested species were shown superior to the latter in terms of biomass productivity [21]. However, since after a number of years this S. viminalis cultivar showed sensitivity to insect attacks, particularly to the potato leaf hopper, and since the risk of epidemic diseases increases as the plantation area expands, a new set of selected clones was investigated.…”

“…Our research team initially set out to identify willow species and clones well-adapted to shortrotation coppice in southern Quebec (Eastern Canada). Our experiments showed that Quebec's climate and soil are very favourable for growing various willow clones in short rotation, and that wastewater sludge can be an effective low-cost and environmentallyfriendly fertilizer [21]. Researchers from Federal and provincial ministries also initiated diverse willow projects during the 1980s and 1990s, including the genetic improvement of hybrid poplar and willow clones adapted to the short growing seasons of boreal forests [22].…”

“…Two species of willow were used: Salix discolor Mtihl., which has been extensively used in our research over the past four years, indigenous to Southern Quebec (Labrecque et al, 1993) and Salix viminalis L., a European species which is commonly planted in intensive cultivation (Christersson, 1986;Nordh, 1992).…”

Fast-growing tree species, such as willows, can benefit from sludge application. While sludges are good fertilizers, they may contain heavy metals which could reduce productivity and cause environment risks. The aims of the present research were to: i) determine the biomass production of Salix discolor Mtihl. and Salix viminalis L. when supplied with various amounts of dried and pelleted sludge and ii) assess the uptake and accumulation of heavy metals. Trials were carried out using unrooted cuttings that were planted in large plastic pots containing sandy soil and grown outdoors for a 20-week period. Five doses of sludge were applied: the equivalents of 0 (TO), 40 (T1), 80 (T2), 120 (T3), 160 (T4) and 200 (T5) kg "available" N ha -l . Trees which received the highest dosage of sludge showed the best growth. Stem biomass was significantly greater for S. viminalis which had received sludge treatments. The relationship between the total biomass yield Y (g) and the rate of fertilization X (equivalent to kg of "available" nitrogen provided per hectare) is linear. Regression equations of predicted biomass production were established as follows: S. discolor, Y = 28.36 + 0.56X and S. viminalis, Y = 39.95 + 0.64X. For both species, the greatest stem biomass per g of N applied was produced with treatments 4 and 5. Amounts of nitrogen per leaf area (N/LA) and per dry leaf mass (N/DL) were higher for S. viminalis. The metal transfer coefficient did not vary between the species but was significantly different for Cd and Zn. Plants were able to absorb Cd and Zn, but were less able to absorb Ni, Hg, Cu, and Pb. It was concluded that the dried and pelleted sludge is a good fertilizer. S. discolor and particularly S. viminalis can be used as filters for the purification of wastewater sludge as well as for biomass production purposes.

This work explores the possibilities of biomass production, for energy purposes, of Siberian elm in Mediterranean areas, including marginal lands with poor soil and low water availability. To achieve this, the influence of soil type, planting density, and water availability on biomass production were analyzed after the first 3 years of the growing cycle in 2 different locations. Moreover, a method to estimate biomass production as a function of some morphological parameters of the trees, as well as the use of leaf water potential as a good indicator of trees' water status, are discussed. The analysis of parameters having an influence on elm growth showed that soil type is the most important factor to obtain a good yield. In soils with enough nutrients and higher water-holding capacity, biomass productions in the range 13-14 Mg DM ha -1 were achieved even under rainfed conditions. In irrigated plots, Siberian elm production was more than double the production of biomass under rainfed conditions; however, significant differences were not found between the 2 different irrigation doses under study. Biomass yield was greater for the highest planting density (6666 plants ha -1 ). Leaf water potential has been shown to be a useful tool for finding out plant water status. Tree growth showed a direct relationship to midmorning leaf water potential, and it was equal to 0 for leaf water potentials lower than -1.83 MPa; this value indicates a great resistance to drought by the species.
