Characterising water limited yield potential in calcareous soils of upper Eyre Peninsula locations
Aims

A better understanding of soil moisture, root disease and factors which influence nutrient availability and the efficacy of fertilisers are needed to increase the water limited yield potential of the highly calcareous soils. Field trials were conducted in 2019 to investigate these factors on the nutrition of wheat on highly calcareous soils.

Key messages
  • Current standard practices of 50 kg/ha DAP or 50 kg/ha MAP balanced with urea below the seed provides adequate P nutrition.
  • With adequate soil moisture, no large differences in grain yield were observed in 2019 at Streaky Bay with different granular fertiliser treatments.
