“…In the present trials, no correlation was found between production and annual mean temperature; nevertheless, Kopp et al [30] reported their results starting from the 4 th year, while this work regards only the first two years from planting. No correlation between production and fertilization was found according to Kopp et al [30] and Hofmann-Schielle et al [20]. Fertilization is a difficult factor to evaluate: the effects can depend on quantity of nutrients, soil type, water availability and root development [20].…”

“…Measures were repeated at the end of the first and second year from planting. Predictor variables included in the analysis were chosen according to literature [19][20][21][22]; data ranges and means are shown in Table 4 separately for the considered species/hybrids. The recorded information was processed through the stepwise regression procedure included in the SPSS 13.0 statistical package using percent plant survival (%) as well as the average biomass production measured at the end of the second year from planting for each clone and experimental trial.…”

Identification of the main site factors and management intensity affecting the establishment of Short-Rotation-Coppices (SRC) in Northern Italy through stepwise regression analysis

Data collected from 183 poplar and 102 willow SRC experimental plots, located in Central-North Italy, were subjected to stepwise regression analysis to acquire information on the environmental factors affecting plant survival and productivity in the first two-year rotation cycle. Nine Populus ×canadensis Mönch, eight P. deltoids Bartr. clones and four hybrids of Salix matsudana Koidz were included in analysis. Independent variables were: annual and seasonal water availability (rainfall and irrigation), annual mean air temperature, soil texture, pH, N and organic matter content, planting density and management intensity. Dependent variables were: a) mean annual yield during the first two-year rotation cycle in tons per hectare per year of dry matter (Odt·ha ); b) plant survival at the end of the second year from planting (%). Water availability resulted the main variable driving plant survival and biomass production in both poplar and willow clones. Water availability appeared to be the principal factor affecting the establishment of poplar and willow energy plantations in the Po valley. Possible variations in the rainfall regime consequent to climate changes could seriously influence land suitability to SRC. Experimental data also indicate that choice of planting density may increase the biomass yield during the first two-year especially with P. deltoides clones. © Versita Sp. z o.o.

Poplar and willow SRC plantations can produce large amounts of dry matter in a relatively short time (e.g. 1-2 years) maintaining their yield capacity throughout many years [1].During the last 5 years about 6000 hectares of energy plantations (Short-Rotation-Coppices, SRC) have been established in Italy, mainly in the Po valley, where biomass thermoelectric power plants are under construction, and the Regional Programs for Rural Development included a series of financial incentives to support the establishment and maintenance of SRC. The planted species were those recommended for the North and Central Italy by the National guidelines for energy plantations [2,3] namely poplars (Populus Cent. Eur.

“…Decomposing leaf litter from the first rotation 11 will provide 81 % of the soil K demand during the second rotation, while fine root turnover will supply 12 approximately 27 kg K ha -1 over the next two rotations. Despite relatively large soil K deficits over 13 multiple rotations, a sizable soil K reserve helps to mitigate the impact, as observed elsewhere 14 [49,57,63]. Returning wood ash to the site can also assist in maintaining soil K fertility [84,103].…”

“…19 A clear understanding of soil nutrient dynamics, particularly the soil nutrient budgets of 20 essential plant nutrients during the establishment phase, is required to accurately forecast the 21 sustainability of the SRC willow production system and the necessity of nutritional amendments. 22 Influential factors include the inherent soil fertility at a given site [76,89], genotypic variability in 23 nutrient requirements, uptake capacity, and/or utilization efficiency [2,121], and genotype × 24 environment interactions [11,49]. In order to account for these effects when developing reliable 25 nutrient budgets for SRC willow production in Saskatchewan, an experiment consisting of several 26 commercial willow varieties was replicated at different sites across a 500 km north-south gradient, 27 covering the range of soils and climate in the province.…”

First Rotation Biomass Production and Nutrient Cycling within Short-Rotation Coppice Willow Plantations in Saskatchewan, Canada

et al. 2014

Abstract:Although numerous studies have quantified different social, economic, energetic, and environmental benefits associated with short-rotation coppice (SRC) willow plantations, comprehensive assessments of nutrient cycling are rare. The objective of this study was to examine the biomass production and attendant biogeochemical cycling of nitrogen (N), phosphorus (P), potassium (K), sulphur (S), calcium (Ca), and magnesium (Mg) during the initial four-year rotation of six willow varieties grown at four locations along a 500 km north-south pedoclimatic gradient within Saskatchewan, Canada. Nutrient budgets consisted of quantifying various nutrient inputs (e.g., atmospheric deposition and soil mineral weathering), outputs (e.g., fine and coarse root biomass, leaf biomass, harvested biomass, leaching, and denitrification), and transfers (e.g., soil organic matter mineralization, canopy exchange, leaf litter decomposition, and fine root turnover) associated with the plant available soil nutrient pool. Total above-and below-ground production during the rotation was approximately 40 Mg ha-1, with calculated soil nutrient budget deficits (i.e., nutrient outputs > inputs + transfers) of 17, 39, 112, 271, and 74 kg ha-1 for N, P, K, Ca, and Mg, respectively, averaged across the varieties and sites, but a soil S surplus of 60 kg ha-1. While soil nutrient budget deficits varied among sites, there were no significant differences (P >0.05) among willow varieties. Despite the relatively low nutrient-demanding nature of willow and negligible leaching or denitrification losses, nutrient export in harvested biomass over multiple rotations will require soil nutrient amendments to maintain SRC willow productivity, particularly N and P, albeit a fraction of the amount required for annual agronomic crops.

A balsam poplar clone (Populus trichocarpa cv. Weser 6) was inoculated by two ectomycorrhizal strains (Laccaria bicolor MW 158 and Paxillus involutus 1444) in Kick‐Brauckmann‐pots. The substrates were two arable sandy soils (Cambisols) with different organic matter content and nutrient supply. One soil (WIL) was rich in organic matter (Corg = 1.6%) and total nitrogen (Nt = 0.14%), whereas the other soil (RIE) had low contents of Corg (0.8%) and Nt (0.08%). Leaf nutrient concentrations, shoot lengths, root and shoot biomass production and nitrogen accumulation in the biomass were determined to discover possible inoculation effects. Mycorrhization indices (% colonized fine roots) of 36% with Laccaria bicolor and 40% with Paxillus involutus were observed on the Corg rich soil (WIL) in contrast to 16% and 14% on the Corg poor soil (RIE), respectively. Inoculation of poplar on the soil WIL increased shoot length, biomass production, shoot:root ratio and total N uptake of the cuttings, whereas on the soil RIE only the shoot:root ratio increased and the N nutrition was improved. We conclude that interactions between soil and fungus should be tested when choosing ectomycorrhizal strains for inoculation.
