The correction of manganese deficiency in barley crops locations
Aims

To establish the most satisfactory method to correct manganese deficiency in barley on calcareous sands

Key messages
  • 67% of divalent manganese incubated on calcareous sands form Warooka was immobilised within 167 hours by chemical and biological processes.
  • In field experiments over seven years manganese up to 16 kg/ha drilled with the barley crop did not prevent manganese deficiency in crops.
  • However, manganese applicaiotn increased crop growth, delayed deficiency symptoms and increased grian yield by an average of 61%.
  • The optimum applicaiotn at seeding was 6 kg/ha manganese (25 kg/ha nanganese sulphate).
  • Three foliar sprays of manganese did not completely correct manganese deficiency.
  •  The best results were obtained by applying 6 kg manganese at sowing followed by three foliar sprays.
