Overview

Meso-scale greenhouse study shows that varied capping designs support vegetation, highlighting microbial diversity's role.

Key Points

  • TSRU tailings with a 30 cm PMM cap supported vegetation for three years, while thicker layers improved growth.
  • Acidification of TSRU tailings was delayed by one year under the thickest capping treatment with PMM and CST.
  • Microbial communities in TSRU tailings were predominantly sulfur oxidizers and acidophiles, indicating low diversity.
  • PMM layers enhanced microbial biomass and stability, suggesting improved potential for plant-microbe interactions.
