Gold processing in Dusun Sangon, Kalirejo Village, Kokap Sub district, Kulonprogo Regency, SpecialRegion of Yogyakarta Province uses amalgamation method. Mercury use in gold processing has apotential impact on environmental damage and health of organism. Therefore, management onmercury-contaminated soil is needed to reduce environmental impacts. However, beforeperforming soil management, it is important to conduct research on initial condition of researchlocation, including research on the soil’s nutrient quality and mercury content. Testing wasconducted in the laboratory. Mercury (Hg) content testing used mercury analyzer testing method.pH testing used ISRIC 6th 2002 method. Organic carbon testing used SNI 13-4720-1998 testingmethod. Total nitrogen testing used SNI 2803-2010 testing method. C/N Ratio testing used SNI 13-4720-1998; SNI 2803-2010 testing methods. Results show that mercury contents in residualsamples of gold ore and soil samples were 4.81 mg/kg and 88.63 mg/kg respectively, which wereincluded in TC-B and TC-A in the aforementioned order. Meanwhile, mercury content in gold oreSamples 1 and 2 were 0.28 ppm and 0.14181 ppm respectively. Soil nutrient content parameters ofOrganic C, Total N, and C/N ratio were found to be very low. These results might be influenced byprocessing activities in gold ore mining.
