Arbuscular mycorrhizal fungi (AMF) improve plant ability to uptake P and tolerate heavy metals. This study aimed to evaluate the effect of available P and the inoculation of Rhizophagus clarus in a Cu-contaminated soil (i) on the activity of acid phosphatases (soil and plant), the presence of glomalin, and (ii) in the biochemical and physiological status of Mucuna cinereum. A Typic Hapludalf soil artificially contaminated by adding 60 mg kg Cu was used in a 3 × 2 factorial design with three replicates.

- The study investigates the effects of arbuscular mycorrhizal (AM) fungi on the growth of Leucaena leucocephala plants subjected to varying concentrations of arsenic (As) in the soil, highlighting AM fungi's role in mitigating the negative impacts of As on plant health.
- Different AM fungi isolates were tested, revealing that those inoculated with AM fungi exhibited improved growth and antioxidant enzyme activity, indicating a protective effect against As toxicity.
- Results suggest that AM fungi enhance the plant's phosphorus to arsenic uptake ratio, thereby promoting greater tolerance to arsenic stress and showing potential for bioremediation strategies in contaminated environments.
Recovery of arsenic contaminated areas is a challenge society faces throughout the world. Revegetation associated with microbial activity can play an essential role in this process. This work investigated biological attributes in a gold mining area with different arsenic contents at different sites under two types of extant revegetation associated with cover layers of the soil: BS, Brachiaria sp.
