Experimental design (Concept: University of Jena)

  • Multi-factorial field experiment with nine test plots (12 m x 4 m each)
  • Soil: a substrate that is contaminated with heavy metals and radio nuclides from mining activities
  • Inoculation of bacteria and mycorrhizal fungi to mobilize pollutants and thus support the biological decontamination via phytoremediation
  • Monitoring of water and solute balance at two soil depths (20 and 50 cm)
  • Data logging at 15 min. intervals, automatic transmission to a data server

How does the addition of bacteria and mycorrhizal fungi, as well as the addition of calcareous soil material, affect the (phyto-) remediation of soils?
