Some zinc-enriched fertilizers are not effective at correcting zinc deficiency locations
Aims

To test the relative effectiveness of a zinc spray to the soil surface compared to zinc-enriched fertilizers for correcting zinc deficiency in wheat.

Key messages
  • Field experiment to test the relative effectiveness of a zinc spray to the soil surface compared to zinc-enriched fertilizers.
  • These results suggest that zinc-enriched fertilizers which are of a heterogeneous nature will not be effective at correcting zinc deficiency in the year of application, or in the following year.
  • Both soil sprays of zinc pre-sowing and zinc-enriched fertilizers drilled with the seed of a homogeneous nature are effective at correcting zinc deficiency.

Fertiliser

The three application types were soil spray of zinc sulphate (applied to soil surface and incorporated with a tyned implement pre-sowing); homogeneous fertilizer (every macronutrient granule coated with zinc and drilled with the seed); and heterogeneous fertilizer (zinc oxysulphate granules separate to macronutrient granules and drilled with the seed). Zinc was applied at 0, 0.625, 1.25, 2.5 or 5 kg Zn/ha.
