AB - This study evaluated the chemical properties of cadmium (Cd)-contaminated soil and reduction in Cd bioavailability following the application of biochar derived from rendered animal carcass residues (RACR-C). The results demonstrated that RACR-C improved soil quality by increasing soil pH, organic matter content, available phosphate, and exchangeable cations. The Cd fractionation analysis revealed the decrease in the highly mobile exchangeable form (F1) and an increase in the carbonate-bound form (F2) derived from biochar. Furthermore, as the RACR-C application rate increase, plant growth improved, while Cd content and uptake decreased. Especially, Cd immobilization led to 60% reduction in Cd uptake in the 10% RACR-C treatment compared to untreated control, effectively suppressing Cd translocation to crops. Therefore, RACR-C is expected to function as a soil amendment and heavy metal stabilizer by improving soil conditions and reducing Cd transfer to plants. Further long-term studies are needed to assess its environmental impact and effectiveness across various crop and soil conditions.
