“…These results are globally coherent with other field studies with average reported yields of 1-2 t ha −1 and max. of 4 t ha −1 (Hammer and Keller 2003;Maxted et al 2007;McGrath et al 2006;Simmons et al 2015). So far, as underlined by Simmons et al (2015), the initial yield predictions of 5 to 10 t ha −1 (Zhao et al 2003) had not been supported by any field trials.…”

“…Phytoextraction with hyperaccumulating plants has been suggested to be a promising technique to remediate soils contaminated with trace metals (Hammer and Keller 2003;Koopmans et al 2008;Maxted et al 2007;McGrath et al 2006;Robinson et al 1998;Schwartz et al 2003;Zhao et al 2003). Hyperaccumulating plants accumulate metals in shoots at concentrations above defined thresholds when grown in their natural habitats, i.e., 100 μg g −1 for Cd, 1000 μg g −1 for Ni, or 3000 μg g −1 for Zn, on a dry weight basis (Krämer 2010;van der Ent et al 2013).…”

“…caerulescens (Brassicaceae, formerly Thlaspi caerulescens) is one of the most promising candidate species for Cd and Zn phytoextraction (Koopmans et al 2008;Maxted et al 2007;McGrath et al 2006;Zhao et al 2003). Three ecotypes of N. caerulescens have been described: metallicolous plants grow in soils enriched in Cd-Zn-Pb (calamine, CAL) and in serpentine sites (mostly enriched in Ni), whereas non-metallicolous (NMET) grow in uncontaminated soils (Escarré et al 2000;Meerts and van Isacker 1997;Molitor et al 2005;Reeves et al 2001).…”

“…These studies concluded that phytoextraction offers a great potential for Cd and Zn remediation achievable in a few crops for moderate soil concentrations. Despite the need of field experiments on a range of soil conditions to assess the actual phytoextraction efficiency, the number of field trials reported in the literature is surprisingly still very scarce (Hammer and Keller 2003;Maxted et al 2007;McGrath et al 2006;Schwartz et al 2003;Simmons et al 2015;Tlustoš et al 2016), in comparison to pot experiments (see 14 references in Li et al 2012). So far, the limits of the method and the biggest lack of knowledge that still need to be field tested concern the adequate agricultural practices, e.g., fertilization, weed and pest control, irrigation and resistance to hot weather, and optimal length of growth (Koopmans et al 2008;Li et al 2012;Maxted et al 2007;McGrath et al 2006;Vangronsveld et al 2009).…”

“…NMET from Luxemburg have never been tested as potential candidates for phytoextraction despite their outstanding metal accumulation capacities (Meerts and Van Isacker 1997), most field studies using the high Cd CAL ecotype (Maxted et al 2007;McGrath et al 2006). Field trials are of crucial importance to assess which soil parameters influence most biomass production and phytoextraction efficiency, and evaluate the potential of the method and its limits.…”

Urban soil contamination with trace metals is a major obstacle to the development of urban agriculture as crops grown in urban gardens are prone to accumulate trace metals up to toxic levels for human consumption. Phytoextraction is considered as a potentially cost-effective alternative to conventional methods such as excavation. Field trials of phytoextraction with Noccaea caerulescens were conducted on urban soils contaminated with Cd, Cu, Pb, and Zn (respectively around 2, 150-200, 400-500, and 400-700 μg g −1 of dry soil). Metallicolous (Ganges population) and non-metallicolous (NMET) populations were compared for biomass production and trace metal uptake. Moreover, we tested the effect of compost and fertilizer addition. Maximal biomass of 5 t ha −1 was obtained with NMET populations on some plots. Compared to Ganges-the high Cd-accumulating ecotype from South of France often used in phytoextraction trials-NMET populations have an advantage for biomass production and for Zn accumulation, with an average Zn uptake of 2.5 times higher. The addition of compost seems detrimental due to metal immobilization in the soil with little or no effect on plant growth.In addition to differences between populations, variations of growth and metal accumulation were mostly explained by soil Cd and Zn concentrations and texture. Our field trials confirm the potential of using N. caerulescens for both Cd and Zn remediation of moderately contaminated soils-with uptake values of up to 200 g Cd ha −1 and 47 kg Zn ha −1 -and show the interest of selecting the adequate population according to the targeted metal.
