Effect of soil and foliar applications of zinc on cadmium concentration in wheat grain locations
Aims

The effectiveness of foliar applications of zinc sulphate to decrease cadmium concentration in wheat grain was assessed at 3 field sites in South Australia.

Key messages
  • Foliar zinc decreased grain cadmium concentration at only one of three sites, when zinc was applied twice.
  • The timing of zinc application had no significant effect on wheat grain cadmium concentration.
  • Soil applied zinc had no effect on wheat grain cadmium concentration.
  • The recommended rate of foliar zinc (0.33 kg Zn/ha) may not be sufficient to decrease cadmium uptake.
