Abstract:
Background and Objective: Soil of post nickel mining open-pit has suffered damage both physical and chemical. This study was aimed to study characteristics of post-mining land, which has been reclaimed and to evaluate its suitability for the development of non-timber crops. Materials and Methods: The soil survey was performed in the nickel reclamation area of PT Vale Indonesian Tbk. in Sorowako, Indonesia. As many as 8 soil profiles were excavated at each randomly selected stratified point at a scale of 1: 50,000. The qualitative method of determining land suitability classes uses the simple limiting factor approaches according to the FAO. Results: These findings showed that the soil permeability, soil cation exchange capacity, base saturation, P2O5 (Bray) content, was rather slow to moderate, soil reaction was acidic and slightly acidic, C-organic was very low to low, total N was very low to low and high of exchangeable Fe. Microscopic observations show primary minerals that are still present in the soil, namely; olivine, pyroxene, biotite and plagioclase, quartz and secondary minerals such as clay minerals (illite, kaolinite chlorite) and opaque. Conclusion: The soil characteristic of the study area still has poor fertility after reclamation. The study area is classified as moderately suitable (S2) and marginally suitable (S3) for non-timber crops. The main limiting factors are nutrient retention (nr), nutrient availability (na), soil depth (rc), slope (eh) and water availability (wa).
