“…The cultivation of fast-growing tree species for soil remediation and the production of renewable energy from contaminated biomass is an alternative approach to more traditional types of land use of post-mining polluted areas [1][2][3][4]. In this context, compared to herbaceous species, fast-growing trees have several advantages, such as a deeper root system, high productivity and transpiration activity.…”

Abstract:The experiment assessed the variability of in seven clones of willow plants of high biomass production (Salix smithiana S-218, Salix smithiana S-150, Salix viminalis S-519, Salix alba S-464, Salix 'Pyramidalis' S-141, Salix dasyclados S-406, Salix rubens S-391). They were planted in a pots for three vegetation periods in three soils differing in the total content of risk elements. Comparing the calculated relative decrease of total metal contents in soils, the phytoextraction potential of willows was obtained for cadmium (Cd) and zinc (Zn), moderately contaminated Cambisol and uncontaminated Chernozem, where aboveground biomass removed about 30% Cd and 5% Zn of the total element content, respectively. The clones showed variability in removing Cd and Zn, depending on soil type and contamination level: S. smithiana (S-150) and S. rubens (S-391) demonstrated the highest phytoextraction effect for Cd and Zn. For lead (Pb) and arsenic (As), the ability to accumulate the aboveground biomass of willows was found to be negligible in both soils. The results confirmed that willow plants show promising results for several elements, mainly for mobile ones like cadmium and zinc in moderate levels of contamination. The differences in accumulation among the clones seemed to be affected more by the properties of clones, not by the soil element concentrations or soil properties. However, confirmation and verification of the results in field conditions as well as more detailed investigation of the mechanisms of cadmium uptake in rhizosphere of willow plants will be determined by further research.

. Poplar clones productivity managed for biomass production in North-Eastern Romania. Bucov. For. 16(1): 73-85.Abstract. Poplar (Populus spp.) is a fast-growing species in temperate conditions, with potential to substitute fossil fuels by obtaining energy from biomass. The aim of this work was to study the productivity of 6 hybrid poplar clone from a hilly region of NE Romania, after a growing season of 4 and, respectively, 5 years. Rods were used as planting material, planted at a density of 2667 trees per ha, with between-row spacing of 3 m and interior-row distances of 1.25 m. Generally, significant differences appear between clones, for all analysed biometric characteristics (p≤0.05). Results show that, in the fifth growing season, diameter increases on average with 15.1%, reaching 11.89 cm, height increases in average with 13.9%, reaching 11.89 m, and volume increases with 33.3%, reaching 0.172 m3. The total biomass after 4 years vegetation varies from 32.8 t/ha to 39.4 t/ha, and after 5 years from 47.7 t/ha to 60.2 t/ha, having an average increase in the latest growing season of 35% and an average yield of 11.3 t/ha/year. The most productive clones in the given growing conditions and crop characteristics are the clone Pannonia after 4 growing seasons and the clone AF6 after 5 years.

“…Further investigations showed that clones with higher shoot hydraulic conductivity and transpiration rate had significantly higher yields (Bungart et al 2000). Cultivation of hybrid poplar (Populus) clones in a short-rotation plantation was an adequate tool for establishing alternative land use systems in the Lusatian post-mining landscape as a potential source of biomass energy (Bungart and Hu¨ttl 2004).…”

Krümmelbein, J., Bens, O., Raab, T. and Naeth, M. A. 2012. A history of lignite coal mining and reclamation practices in Lusatia, eastern Germany. Can. J. Soil Sci. 92: 53–66. Germany is the world's leading lignite coal producer. The region surrounding the towns of Cottbus and Senftenberg in Lusatia, Eastern Germany, is one of the largest mining areas in Germany, and has economically been strongly dependent on lignite mining and lignite processing industries since the middle of the 19th century. We introduce the area, give a brief historical overview of lignite mining techniques and concentrate on post-mining recultivation (reclamation) to agricultural and forestry dominated landscapes. An overview of the physical and chemical limitations for reclamation of the Tertiary and Quaternary substrates due to their natural composition and the technical processes of mine site construction is provided. We introduce some recultivation practices and end with a display of land uses before and after mining and an outlook on the future use of the reclaimed landscape. This review serves as a defined perspective on long-term coal mine reclamation from which to address global similarities and contrasts.
