Combined effects of green manure returning and addition of sewage sludge compost on plant growth and microorganism communities in gold tailings.

Remediation of gold tailings is often difficult due to their extremely barren nature and highly heavy metal concentrations. Returning green manure and applying sewage sludge compost have the beneficial effects of providing nutrients and improving the soil environment. The effects of green manure plants, alfalfa (Medicago sativa L.

The influences of arbuscular mycorrhizal fungus on phytostabilization of lead/zinc tailings using four plant species.

A greenhouse experiment was conducted to investigate the effects of the arbuscular mycorrhizal fungus Funneliformis mosseae on three parameters: Pb, Zn, Cu and Cd accumulation, translocation and plant growth in perennial ryegrass (Lolium perenne), tall fescue (Festuca arundinacea), showy stonecrop (Hylotelephium spectabile) and Purple Heart (Tradescantia pallida). The purpose of this work is to enhance site-specific phytostabilization of lead/zinc mine tailings using native plant species. The results showed that mycorrhizal fungi inoculation significantly increased plant biomass of F.
