Responses to deep placement of phosphorus and potassium in chickpea—Comet River locations
Aims

This project is gathering data from these trial sites to ascertain whether a one-off application of either P, K or sulfur (S) placed in these
deeper, more depleted layers can provide a grain yield benefit and whether that benefit can be maintained over several years.

Key messages

1. 20% yield response to deep-placed phosphorus at the highest rate in the third year of production.
2. No significant response to deep-placed potassium.
