Schematic diagram of the experimental approach. Legend: MT t0 = tailing material at the sampling moment (wet state, at three locations on the tailing dam), different types of Technosol, in pot experiments: MT = homogenized dry tailing material, MTTS = MT with topsoil, MTTSTr = MT with topsoil and Trifolium green fertilizer, MTTSTrF1 = MTTSTr inoculated with 1% mycorrhizal fungi, MTTSTrF2 = MTTSTr inoculated with 2% mycorrhizal fungi.
