Metal(loid) soil pollution is a major environmental and health issue, requiring these areas to be remediated, for example through phytoremediation processes. In order to allow proper plant establishment and growth, amendments must be applied to highly contaminated and poorly fertile soils. Amendments are diverse, but many studies have shown the beneficial effects of biochar, manure and ochre, although studies on their combined use are scarce. Moreover, no studies have evaluated the effect of these combined amendments on endemic plant growth. Endemic plants growing on contaminated soils showed higher tolerance toward pollutants compared to plants coming from unpolluted areas. Therefore, the aim of the present study was to evaluate both the effect of amendments (single or combined) on the physicochemical properties of a former mining technosol, and the growth and metal(loid) accumulation ability of endemic Agrostis capillaris plants. This study revealed an improvement in the soil physicochemical properties following the application of amendments, with combined amendments showing better results than the application of just one. On top of this, Agrostis plants performed better on the amended technosols, especially the ones receiving manure, due to its high nutrient content. Finally, based on soil properties, plant growth and the metal(loid) accumulation profile, the use of biochar combined with manure seems to be the most appropriate treatment. Indeed, this treatment showed an improvement in both soil fertility and plant growth. Moreover, Agrostis plants grown in these conditions were among those showing higher root metal(loid) concentration associated with a lower translocation toward aerial parts.

与毛细孢菌的金属生态型有关的生物炭，cher石和粪肥改良剂对前矿山甲硝酚的As和Pb稳定性的影响。

金属（土壤）污染是主要的环境和健康问题，需要对这些区域进行补救，例如通过植物修复过程。为了使植物能够正常生长和生长，必须对高度污染和肥沃的土壤进行改良。修正案千差万别，但许多研究显示了生物炭，粪便和石的有益作用，尽管对它们的联合使用的研究很少。此外，尚无研究评估这些联合修正对特有植物生长的影响。与来自未污染地区的植物相比，在受污染的土壤上生长的特有植物对污染物的耐受性更高。因此，本研究的目的是评估修订（单一或组合）对以前采矿技术的物理化学性质的影响，特有的草ros毛植物的生长和金属（胶体）的积累能力。这项研究表明，施用改良剂后土壤理化性质有所改善，联合改良剂的效果比仅施用一种改良剂更好。最重要的是，Agrostis的植物在改良后的Technosol上表现更好，尤其是那些接受肥料的植物，因为其营养成分高。最后，根据土壤特性，植物生长和金属（金属）积累状况，将生物炭与肥料结合使用似乎是最合适的处理方法。实际上，这种处理显示出土壤肥力和植物生长的改善。此外，
