Trial location(s) Moora, WA
Potassium strategies for wheat locations
Aims

This trial examines potassium (K) rates as muriate of potash (MOP) products applied by a number of methods and the effects on growth and yield of Mace wheat.

Key messages
  • Sandplain soil with Colwell K analysis lower than 30 mg/kg is highly likely to be responsive to K.
  • Potassium applied at 13-17 kg/ha in the compound NPK+traces fertiliser, Vigour, banded below the seed improved yields compared to NP+traces compound alone, and yields were further enhanced by applying additional 12.5 kg/ha K as MOP.
  • Optimised returns will depend fertiliser and grain prices at the time. In the present trial, the greatest increase in returns were seen with Vigour 140 kg/ha at seeding plus 25 kg/ha MOP applied PSPE.
