Abstract
Soil recovery in minesites is a complex process and needs various methods to measure the progress. Objective: This study integrated static closed-chamber technique together with several soil variables. Method: Soil respiration used 25 ml of 0.25 M KOH and measured with a portable EC-meter. Land reclamation was located in Banko Barat, Tanjung Enim, South Sumatra, which has been revegetated in 1997, 2000, 2007 and 2013. Results: Revegetation patterns have remained relatively the same. Types of plants are generally Acacia, Eucalyptus, Albizia with some local species including mahogany. Post-mining land showed a trend to improve with age reclamation by soil respiration rate. The old location (1997) has a hourly rate of 500 mg CO2/m2. A warmer temperature may lead to higher hourly rate in recently planted 2013 site (680 mg CO2/m2). Soil organic carbon increased significantly (5.41 ± 3.64 %) while soil pH was still acidic (3.61 ± 0.42). Conclusions: Soil recovery may be related to increasing soil respiration, organic carbon, and soil pH. Plant selection is important to ensure future success of site rehabilitation.
