dc.description.abstractEnMiscanthus giganteus was planted on five field plots with Cu-contaminated soils at a former wood preservation site for assessing its Cu-tolerance and suitability to both produce a high biomass with financial opportunities and provide ecosystem services. Four plots display Cu-contaminated soils (i.e. plots #10, 20, 30, and 31 had 306, 163, 1170, and 1016 mg Cu kg-1) and one plot soil Cu and PAH contamination (P7: 467 mg Cu kg-1). Soils were amended with compost and dolomitic limestone either 4 years or 1 month (P7) prior plantation, except in the untreated plot #31 (Unt). Rhizome density was 50 000/ha. Maximum shoot height and biomass of 1-yr and 2-yr-old plants were recorded. Shoot ionome of 1-yr-old plant was determined. Six out of 10 plants survived in the Unt plot #31 and displayed high shoot Cu concentration (507 ± 145 mg kg-1). All plants developed in amended plots. Shoot biomass and height were higher and shoot Cu concentration lower (down to 17 mg kg-1) in amended plots than in the Unt plot, highlighting the influence of organic matter, soil pH and Ca/Mg nutrition. Despite soil N fertilization, the P7 plants showed foliar N deficiency symptoms. Suitability of M. giganteus and soil amendment to phytomanage these soils will be long-term monitored
