The role of microorganisms in colonizing toxic smelter waste deposits by plants has not been sufficiently understood. The aim of the work was to assess interactions between microorganisms and most frequent spontaneous plants inhabiting two waste deposits in Piekary, Poland. The samples were collected in the summer of 2018 from rhizosphere of 8 plant species inhabiting the waste pile: 1. Thymus serpyllum; 2. Silene vulgaris; 3. Solidago virgaurea; 4. Echium vulgare; 5. Rumex acetosa; 6. Verbascum thapsus; 7. Solidago gigantea; 8. Eupatorium cannabinum. The samples were subjected to analyzes of enzymatic activity, abundance of microorganisms, functional (System Biolog) and genetic diversity (NGS), physicochemical properties (pH, metal content and solubility, nutrient content) and subsequently compared with the unplanted reference samples. Plant samples were analyzed for metals and nutrient contents.
