Abstract

The effect of tin mining activity increased sand fraction, decreased silt and clay fractions, decreased macro and micro nutrients especially phosphate and potassium. Vegetation structure and composition were changed. Consequently biotechnology approach such as the use of arbuscular mycorrhizal fungi for supporting revegetation on tin-mined land was needed. The aim of this research was to identify the status of arbuscular mycorrhizal fungi in the succession on tin-mined land in Bangka Island. Composites of eight subsamples of rhizosphere were taken at 0-20 cm soil depth under three dominant vegetations at a lowland forest, an abandoned farmed-land, and at 4-, 7-, 11-, and 38-year old tin-mined lands using a modified CSM-BGBD Project 2004 protocol. Spores were separated from soil by a wet sieving method and identified referring to INVAM. The results showed that at succession on tin-mined land, the less phosphate concentration in the soil, the more the average number of spore per dominant vegetation. The average spore number per 50 g soil at 0-20 cm depth were 2.0 (4 year old and barren tin-mined land); 46.4 (7-year old tin-mined land); 56.8 (11-year old tin-mined land); and 261.8 (38-year old tin-mined land); while 45.3 at an abandoned farmed-land; and 15.1 at a forest. The spore number tended to decrease as the more newly abandoned tin-mined land. Glomus was dominant at all study sites, either at tin-mined lands or at a forest and at an abandoned farmed-land. This genus was predicted to have a vast distribution and potential as an inoculum at tin-mined lands.
