Root towers - Tracer methods and ingrowth cores

  • Plastic bags cover plants in order to collect transpiration water from the plant containing isotope tracers
  • Injecting isotope water or 15N at different depths
  • Testing drought conditions in top layers of soil
  • Irrigation of each chamber at the top of the towers
  • Ingrowth core from root tower
  • Ingrowth cores with roots and soil collected from root towers
