Synergistic application of canna-derived biochar and arbuscular mycorrhizal fungi enhances cadmium immobilization and soil ecological function in contaminated soils.

ABSTRACT: Cadmium (Cd) is a highly toxic and persistent heavy metal pollutant that poses a serious threat to soil ecosystems and food safety. In this study, biochar derived from three wetland plants (reed, typha, and canna) at various pyrolysis temperatures were evaluated for their capacity to immobilize Cd in contaminated soil. Canna-derived biochar prepared at 500 °C (Ca500) exhibited the most favorable physicochemical properties, including a high surface area and a developed porous structure. Subsequently, ICP-MS analysis, antioxidant activity assays, and microbial community analysis were conducted to further investigate the effects of combined Ca500 and arbuscular mycorrhizal fungi (AMF) application on Cd immobilization in soil and on soil microbial communities. The results revealed that co-appl
