| dc.description.abstract | Reliance on natural succession to restore sand tin tailings without any human aid can be very slow (Mitchell 1959; Nurtjahya et al. 2007a). Natural regeneration after up to 11 years on tin-mined land in Indonesia was dominated by shrub species of the Cyperaceae and Poaceae families while shrub species of the Myrtaceae family were still common on 38-year old tin-mined lands. The cation exchange capacity and concentrations of soil nutrients (Ca, Mg, K, and Na) of tin-mined lands were lower than undisturbed land, and the carbon to nitrogen ratio of tin-mined lands was higher than undisturbed lands (Nurtjahya et al. 2007a), inhibiting natural regeneration of tree species. | id |
