Copper is among eight essential micronutrients for plant growth. Like other metals, due to human activity in the Anthropocene, it behaves as an important pollutant in the biosphere. In this context, this study aims to identify the potential of the plant species Cyperus rotundus L. (nutgrass) in the treatment of copper-contaminated soils to observe: the reduction in the amount of copper in the soil after experiment, difference in fresh and dry mass and chemical parameters such as electrical conductivity (EC) and soil hydrogen potential (pH). According to the parameters analyzed, nutgrass demonstrated significantly greater efficiency in phytoextraction when copper levels in the soil were at higher doses. This adaptive response indicates that the plant has a high capacity for copper accumulation in conditions of high contamination, which makes its use viable as an effective strategy for decontaminating soils saturated with this metal. Therefore, nutsedge proves to be a promising candidate for use in the phytoremediation technique, particularly in areas where copper contamination reaches critical levels.
