This study evaluated the phytoremediation of mine tailing-contaminated soils in Quiulacocha, Peru, using combined application biochar and compost, with Zea mays L. (maize) serving as phytoremediator due to its high biomass production stress tolerance. A factorial experimental design was implemented, varying two main factors: mining tailings dose (30% 60% w/w) pyrolysis temperature (300 °C 500 °C).

Soil contamination with heavy metals (HMs) poses a significant environmental threat. Phytoremediation, sustainable and eco-friendly emerging bioremediation approach, utilizes plants to remove, immobilize, or stabilize soil contaminants. This study examines the interactive effects of sulfur (S), ethylenediaminetetraacetic acid (EDTA), olive mill wastewater (OMW) on HM uptake growth maize (Zea mays L.) mustard (Brassica juncea). Mustard exhibited superior dry matter (DM) yield (2.4 g/pot 5% OMW), nutrient uptake, tolerance metal toxicity. The translocation factor (TF) bioaccumulation (BF) for vary significantly different treatments. For maize, S 2T/ha treatment achieved highest TF BF cadmium (Cd), while OMW led maximum chromium (Cr) manganese (Mn) uptake. In mustard, resulted in greatest bioconcentration (BCF) lead (Pb), zinc (Zn), whereas application yielded Cd. overall enhanced most significantly. Lower rate (1 ton/hectare) increased availability Cd Pb, boosting plant instance, 1 ton/hectare elevated 24.102 mg·kg−1 58.705 mustard. EDTA treatments further improved bioavailability, increasing levels (10.09 mg·kg−1) (7.78 mg·kg−1). Mustard’s efficiency identify it as promising candidate phytoremediation HM-contaminated soils arid regions. Innovative sulfur, EDTA, enhance decontamination growth.
