Distribution of P, K, Ca, Mg, Cd, Cu, Fe, Mn, Pb and Zn in wood and bark age classes of willows and poplars used for phytoextraction on soils contaminated by risk elements

Popis výsledku v původním jazyce

Fast-growing clones of Salix and Populus have been studied for remediation of soils contaminated by risk elements (RE; Cd-, Pb- and Zn-) using short-rotation coppice plantations. We assessed biomass yield and distributions of elements in wood and bark of 4 clones (S1 — [Salix schwerinii S. viminalis] S. viminalis, S2 — S. smithiana, P1 – Populus maximowiczii P. nigra, P2 — P. nigra) with respect to aging. Shoots were harvested after four seasons and separated into annual classes of wood and bark. All tested clones grew on contaminated soils, with highest biomass production and lowest mortality exhibited by P1 and S2. Concentrations of elements, with exception of Ca and Pb, decreased with age and were higher in bark than in wood. The Salix clones were characterised by higher removal of Cd, Mn and Zn compared to the Populus clones. Despite generally higher RE content in young shoots, partly due to lower wood/bark ratios and higher RE concentrations in bark, the overall removal of RE was higher in older wood classes due to higher biomass yield. Thus, longer rotations seem to be more effective when phytoextraction strategy is considered. Of the four selected clones, S1 exhibited the best removal of Cd and Zn and is a good candidate for phytoextraction.
