Potential for foliar applied phosphorus in Australian dryland cropping: a glasshouse study locations
Aims

To accurately measure the ability of foliar P products to increase grain yield and contribute to grain P uptake using a radioactive tracing technique (with 33P) in the glasshouse.

Key messages
  • A yield response to foliar phosphoric acid plus adjuvant was measured in a P responsive soil type.
  • Translocation to grain did not control the yield response but likely due to the increased ability of the tillers to survive and fill grain.
  • Further evaluation is required of the; soil types, climatic conditions, timing, rate and formulations including adjuvants, in order to determine the best fit for foliar P fertilisation in agricultural systems having variable climate.
