- A long term experiment was conducted to verify the phytoremediation effect of large biomass plants and to seek the balance between remediation effect and economy. Eucalyptus globulus were planted with rotation periods of respectively 3, 6 and 9 years to examine the effect on soil remediation. Biomass and concentrations of Cd, Pb and Cu in E. globulus were measured after each harvest. The economic value of the plant was estimated. Results showed E3 (9th year uprooted) had the best soil remediation effect and economic benefit. Therefore, soil remediation and economy were best balanced when E. globulus were not cut.
