Soil in the karst region usually features high geogenic cadmium (Cd) and limited available phosphorus (P). Appropriate phosphate amendment is crucial for alleviating Cd accumulation food crops reducing health risks. However, interaction of P Cd-rich soil-plant systems poorly understood. In this study, a pot experiment was conducted to investigate translocation soil-pepper system under different rates Ca(H2PO4)2. The results showed that biomass pepper not affected by application Ca(H2PO4)2, even up 0.45 g/kg, but nitrogen potassium fertilizers. High contents total (6.19 mg/kg) bioavailable (2.72 mg/kg, 44%) studied soils resulted elevated content pepper, it decreased order root (8.18 > stem (4.89 fruit (3.88 mg/kg). This indicates planted may present potential Furthermore, neither influences rhizosphere soil nor uptake transport plants. findings study highlight monocalcium suitable choice fruits other remediation strategies are needed.
