Abstract:
Mining, including tin mining, is considered as
critical factor destroying ecosystem leads to the major deleterious soil
quality in affected area in all over the world. It is urgently a must to
develop environmental friendly technology to reclaim mining impacted area to be
suitable and productive for further potential use after mining. Beneficial soil
microorganism i.e.: mycorrhizal fungi, Rhizobium
sp., and phosphate solubilizing
microorganism are well-known in providing additional available nutrient for
plant. This research aimed (1) to select beneficial soil microorganism
collected from post tin mining area based on their ability in increasing
nutrient availability, solubility, in improving nutrient uptake, and increasing
plant growth, (2) to get the best isolate of beneficial soil microorganism
collected from post tin mining area. There were three groups of beneficial
microorganisms used: (1) Three type of Rhizobium; (2) 17 type of P-solubilizing
microorganisms; (3) arbuscular mycorrhizal fungi. All collected beneficial
microorganisms were screened for its ability in improving plant growth and
development by inoculate it into seedlings. For early screening, sterilized
sand was used the growth media. For early evaluation of these microorganisms,
tin tailing and tin tailing+10% compost were used as the growth media. The
results exhibited that all inoculation of Rhizobium significantly increased
growth of Paraserianthes falcataria when
growing in tin tailing+10% compost. P-solubilizing microorganism significantly
enhanced growth of Eucalyptus pellita when
growing in both tin tailing and tin tailing with additional of 10% compost.
Arbuscular mycorrhizal fungi only increased Eucalytus
pellita when growing in tin tailing. These results imply that selection of
native beneficial microorganisms may be a promising method in developing biotechnology
for restoration of degraded mining area.
