Climate change, deforestation, and substantial loss of agricultural land within gold mining concessions in Dharmasraya greatly affect soil carbon stocks (Cs). This study used a survey method with purposive random sampling based on variations in ex-gold mining areas in each region, at depths of 0-20 and 20-40 cm with three to five replicates with a total of 54 samples. The estimation of Cs in ex-gold mining soil was highest at a depth of 20-40 cm (5.89E2), compared to a depth of 0-20 cm (1.38E2), where bulk density (BD), soil organic carbon (SOC), and total Hg in ex-gold mining soil at a depth of 0-20 and 20-40 cm were 1.46 and 1.39 g cm-3; 0.03 and 0.05%; 4.11 and 4.25 mg kg-1, respectively. The Cs in ex-gold mining soil at a depth of 0-20 cm is very significant by BD (r=-0.522** or Cs=-628.03(BD)+1055.1; R²=0.275) and SOC (r=0.948** or Cs=4896.8(SOC)-6.4673; R²=0.8996) and total Hg (r=0.518** or Cs=81.373(Hg)-196.43; R²=0.2688). However, at a depth of 20-40 cm, it was very significant by SOC (r=0.836** or Cs=16666(SOC)-196.03; R²=0.699).
