Revegetation as a driver of chemical and physical soil property changes in a post-mining landscape of East Kalimantan: A chronosequence study

As a result of mixing soil materials from various natural horizons, mine soils generally have low organic C and total N content. In wet tropical climates where the vegetation is evergreen, we hypothesize that with start revegetation, levels will recover rapidly increase as time since revegetation increases. The in content implications for changes other chemical physical properties. development climate conditions so far rarely considered only. This study aims to determine properties initial stages formation triggered by increasing revegetation. Soils permanent observation plots ex-coal mined sites divided (0–12 years) were sampled together an adjacent site forest. Decisive determined 0 30 cm depth. With there was decrease bulk density, porosity following logarithmic equation. Linear found C, N, available P levels. linear levels, density suggest these parameters are controlled development, while polynomial extractable K (25% HCl), CEC, exchangeable bases, base saturation percentage, Al over can be assigned processes independent highly dependent on composition original substrate.
