Abstract: The role and importance of soil microorganisms (PGPR and ECM fungi) in promoting the health, growth, and nutrition of Picea glauca were investigated on biotite-quartz-rich waste rocks and fine tailings of Sigma-Lamaque gold mine located in the Abitibi region of Canada. The study was divided into three components. Firstly, the community structure of ECM fungi associated with Picea glauca was analyzed on four locations near the mining site. Secondly, a laboratory experiment was conducted in order to in vitro select promising ECM fungi that were growing well on mine tailings. Thirdly, a glasshouse experiment involving the growth of Picea glauca seedlings on waste rocks and fine tailings was conducted and the performance of different treatments of ECM fungi and PGPR was evaluated. Results suggested that site-adapted ECM fungi and PGPR play a very important role in the health and growth of Picea glauca on biotite-quartz-rich waste rocks and fine tailings.
