To investigate the benefits of speciality phosphorus products and liquid phosphorus options in cereals.
This trial sight was chosen as a typical regional soil type and had had a representative cropping rotation. Unfortunately the soil phosphorus levels (Colwell P) show that this site was possibly not phosphorus responsive as required for the purposes of this trial.
Adequate winter and late spring rains resulted in average grain yields. The trial was never moisture stressed and high grain protein levels indicate that the trial was not stressed for nitrogen. Visually it was difficult to pick any differences between treatments during the growing season.
