Correction of zinc deficiency in linseed on the Darling Downs, Queensland locations
Aims

To test methods for alleviating zinc deficiency in linseed.

Key messages
  • Zinc applied as a 0.5% zinc sulphate spray completely corrected symptoms of zinc deficiency in field trials.
  • Increasing the concentration of zinc sulphate (0.5, 1 and 1.5%) or applying twice did not affect plant response.
  • To be fully effective sprays had to be applied two weeks after emergence.
  • Soil applications of 125 kg/ha zinc sulphate were fully effective but not lesser rates.
