Nutrition packages for wheat on sands - fertiliser placement locations
Aims

To to establish if;

  • Supplying 50 kg DAP/ha with seed had a consistent yield penalty, and
  • If wheat yield could be improved by altering the placement of sowing fertiliser.
Key messages
  • Wheat fertilised with DAP placed with seed yielded 0.5 t/ha (20%) less than wheat with DAP placed below seed in 2017 at Loxton but had no effect at Karoonda.
  • Using 50 kg DAP/ha with the seed and 35 kg Urea/ha deep was better than 50 kg DAP/ha and 35 kg Urea/ha all below the seed on sand at Loxton.

Fertiliser
  • All plots received a pre-sowing application equivalent to 33 kg/ha of potassium sulfate to supply K and S, and an in-crop foliar application of Zn, Cu and Mn.
  • Fertiliser placed below the seed was approximately 5cm below seeding depth (3 cm)
  • Fertiliser with seed

    50 kg DAP/ha

    Herbicide
