Effectiveness of fertiliser sources of zinc locations
Aims

To assess the relative effectiveness of a range of products at correcting zinc (Zn) deficiency in wheat.

Key messages
  • Three field trials assessed the relative effectiveness of a range of products for correcting zinc deficiency in wheat.
  • These trials were conducted during the 1996 growing season and were located in representative areas of the Lower Eyre Peninsula and Lower North regions of SA and the Wimmera of Vic.
  • They were predicted to be Zn deficient but moderate responses to Zn fertilisers were recorded at only the two SA sites.
  • Responses to Zn in grain yield at these two sites were too small to assess any relative differences between fertiliser sources but assessments of dry matter production and Zn uptake during the season allowed some relative comparisons to be made.
  • The technique of spraying a zinc sulphate solution onto the soil surface and incorporating prior to seeding was the most effective technique at supplying Zn to the wheat crop under the conditions of these trials.
  • Under the conditions of the trials reported here there was no clear evidence that DAP sources of Zn enriched fertilisers were less effective than MAP sources.
  • However, the behaviour of these two different product types was not tested under severe Zn deficiency conditions.
