Popularly known as Maricá or skyscraper, Mimosa bimucronata (DC.) Kuntze is considered an arboreal tree or shrub, accented, commonly 3 to 10 m high, particularly adaptable to different types of soils and climates, with high germinative power (on average 70%), in its characteristics it has a very long pivoting root favoring the absorption of nutrients and minerals from the soil and tends to reach maturity in 7 years. In phytoremediation plants can act directly or indirectly to reduce or remove contaminants. In direct remediation, the compounds are absorbed and accumulated or metabolized in the tissues, through their mineralization. Indirectly, vegetables extract contaminants from groundwater, thus reducing the source of contamination or when the presence of plants provides a favorable environment for increasing microbial activity, which degrades the contaminant. The following work aimed to verify the effectiveness of using Mimosa bimucronata (DC.) Kuntze as a phytoremediation species in an Oxisol contaminated by different concentrations of iron in the form of ferrous sulfate (FeSO4).
