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.
