Responses to phosphorus and potassium by winter crops in Southern Queensland locations
Aims

This research is questioning if placing immobile nutrients deeper into the soil can increase grain yield.

Key messages

1. Wheat at Condamine and late barley at Jimbour West both had yield increases with starter and deep-P independently.
2. Chickpea at both Roma sites had no effect of starter or deep-P on grain yield, with little in-crop rain restricting yield potential.
3. Potassium (K) had no yield effect on late barley at Jimbour West.
