Residual nutrition in WA’s HRZ – Gibson 2021 locations
Aims

To investigate whether residual soil nutrition from canola grown with high fertiliser inputs should influence nutrition strategies in the following wheat crop.

Key messages
  • Residual effects of high rates of nitrogen, sulfur and phosphorus applied to canola could be detected in soil tests prior to seeding wheat in the following season.
  • Nitrogen applied to the wheat crop had a much larger impact (1 t/ha grain yield increase) than carryover effects of nitrogen applied to the canola crop (up to 0.6% grain protein concentration increase).
  • Phosphorus rates applied to canola influenced the yield of the following wheat crop only when no P was applied to the wheat, with no difference in yield when 27 kg P/ha was applied at seeding of the wheat.
  • Growers in WA’s high rainfall zone are unlikely to see meaningful carryover effects in the cereal phase from high rates of nutrition applied to canola the year prior. They should, therefore, continue to focus on expected responses in the current year only when determining the most profitable rates of fertiliser to apply to their crops.
