Miscanthus x giganteus is suggested as a good candidate for phytostabilization of metal-polluted soils. Its late harvest in winter generates large amounts of leaf litter on the soil surface.

Ex situ artificial aging for 1, 3, and 6 months was conducted with miscanthus leaf fragments incorporated into three agricultural soils displaying a gradient concentration in Cd (0.6, 3.1 and 7.9 mg kg−1), Pb (32.0, 194.6 and 468.6 mg kg−1), and Zn (48.4, 276.3 and 490.2 mg kg−1) to simulate the leaf litter input over 20 years of miscanthus culture.

The breakdown of poplar litter on the four plots was monitored during 10 months. In parallel, colonization of litter bags by functional groups of mesofauna (Collembola and Acari) was followed. Two mesh sized litter-bags were used to allow distinguishing microbial and mesofaunal actions on the litter breakdown. We observed the breakdown of litter in four
studied plots. Litter breakdown occurred faster in 3 mm litter bags than 250 µm ones during summer demonstrating the importance of mesofauna. Mixed plantation allowed faster litter breakdown than mono-specific plantation. A higher abundance of mesofauna and/or better abiotic conditions (moisture, shading…) could explain this result. Regarding litter breakdown and mesofauna, no significant difference was observed between the amended plots and those subjected to soil phytomanagement. However, communities of the studied area are disturbed since a low abundance of detritivores was observed. This could explain also the slower litter breakdown than expected in our study. To conclude,
among the phytomanagement methods tested, mixed plantations could provide a benefit for the restoration of degraded soils. By contrast, the use of fly-ashes does not seem to have any effect on the functionality of ecosystem neither on the litter breakdown process nor on the abundance of mesofauna.},

abstract = {The choice of agronomic practices for phytomanagement of metal-contaminated soils is of crucial importance to optimize plant biomass yields and to mitigate both environmental and health risks due to metal exposure. the present study aimed to assess the effects of agronomic practices on shoot yield and on metal (cd, pb, and zn) accumulation in the organs of the energy crop miscanthus (miscanthus × giganteus) during the first three years since the plantation on metal-contaminated agricultural soils. three miscanthus cultivars, hereafter named mis-a, mis-b and mis-i, were planted at low and high density. an inoculum of arbuscular mycorrhizal fungi-amf (glomus lpa val 1) was added during plantation, and nitrogen fertilization was applied during the third growing season. metal accumulation in miscanthus organs was determined during the second growing season, whereas shoot yields and their metal concentrations were determined during both the second and the third growing seasons. based on metal concentrations and bioconcentration factors, the three cultivars mainly accumulated metals in their roots. the shoot yields increased from 3.7 to 10.3 t dw ha−1 in the second growing season to 15.8–23.3 t dw ha−1 in third growing season. there were no or very few significant differences in metal concentrations and shoot yields within treatments comprising the same cultivar. the addition of amf inoculum increased metal (mainly cd and zn) accumulation in miscanthus organs and in the shoot yields and this was more observed in both mis-b and mis-i which presented a higher root mycorrhization level than in mis-a. shoot yields in treatments comprising different cultivars depended not on fertilization but on the interactions between cultivar and planting density, and between cultivar, planting density and amf inoculum. whatever the treatment and the sampling period, pb concentrations did not significantly differ in shoot yields. the interaction between cultivar and planting density resulted in higher cd concentrations in the yields of mis-b planted at low density during the third growing season. zn concentrations increased with fertilization in all treatments, and with the addition of the amf inoculum in mis-b and in mis-i. overall, the results demonstrated that the three cultivars could be potential candidates for coupling phytostabilization and biomass production on metal-contaminated soils.},

The choice of agronomic practices for phytomanagement of metal-contaminated soils is of crucial importance to optimize plant biomass yields and to mitigate both environmental and health risks due to metal exposure. the present study aimed to assess the effects of agronomic practices on shoot yield and on metal (cd, pb, and zn) accumulation in the organs of the energy crop miscanthus (miscanthus × giganteus) during the first three years since the plantation on metal-contaminated agricultural soils. three miscanthus cultivars, hereafter named mis-a, mis-b and mis-i, were planted at low and high density. an inoculum of arbuscular mycorrhizal fungi-amf (glomus lpa val 1) was added during plantation, and nitrogen fertilization was applied during the third growing season. metal accumulation in miscanthus organs was determined during the second growing season, whereas shoot yields and their metal concentrations were determined during both the second and the third growing seasons. based on metal concentrations and bioconcentration factors, the three cultivars mainly accumulated metals in their roots. the shoot yields increased from 3.7 to 10.3 t dw ha−1 in the second growing season to 15.8–23.3 t dw ha−1 in third growing season. there were no or very few significant differences in metal concentrations and shoot yields within treatments comprising the same cultivar. the addition of amf inoculum increased metal (mainly cd and zn) accumulation in miscanthus organs and in the shoot yields and this was more observed in both mis-b and mis-i which presented a higher root mycorrhization level than in mis-a. shoot yields in treatments comprising different cultivars depended not on fertilization but on the interactions between cultivar and planting density, and between cultivar, planting density and amf inoculum. whatever the treatment and the sampling period, pb concentrations did not significantly differ in shoot yields. the interaction between cultivar and planting density resulted in higher cd concentrations in the yields of mis-b planted at low density during the third growing season. zn concentrations increased with fertilization in all treatments, and with the addition of the amf inoculum in mis-b and in mis-i. overall, the results demonstrated that the three cultivars could be potential candidates for coupling phytostabilization and biomass production on metal-contaminated soils. |
