Cadmium phytoextraction using short-rotation coppice Salix: the evidence trail.
A substantial body of evidence has now accumulated that raises expectations that clean-up of Cd-contaminated land can be achieved through cultivation and harvest of selected clones of short-rotation coppice willow within a realistic crop lifecycle. Cd uptake rates into Salix are high compared to other trace elements and to other plant species. Effective phytoextraction would require (i) careful targeting of hotspots, (ii) repeated harvest prior to leaf fall and (iii) final removal of the root bole.
