The phytoremediation potential of the halophytic plant, Tamarix smyrnensis (T. smyrnensis), was examined in toxic metal spoils assisted by biochar and irrigation air nanobubbles. substrate (spoil) used present study derived from areas close to laterite (Ni-containing ores) mines. efficiency addition two rates (5 t/ha 20 t/ha) improve microbial properties stabilize soil aggregates also examined. Furthermore, effect with air-nanobubble-supplemented water evaluated for remediation spoils. physiological condition plant species investigated terms biomass, height, chlorophyll content, antioxidant enzymes. alkali heavy accumulation their distribution parts were assessed explore whether metals could accumulate root further translocate aboveground tissues. growth T. not adversely affected its cultivation lateritic spoil, highest rate exhibited a beneficial on weight (aerial subterranean biomass). application led significant increases total showing 97.6% increase when is alone 136% combined nanobubble irrigation. Remarkably, only combining nanobubbles low supplementation did translocation tissues occur as factor estimated be greater than unity (TF > 1). bioconcentration factors remained below 1.0 (BCF < 1) across all treatments, demonstrating limited mobilization despite amendments. Finally, increased slightly but substantially uptake metals, which showed decrease compared control groups lower dosage utilized.
