Optimising fertilizer and seed rates according to production zone.

Ivan and Helen Lee

Rotation : Wheat 00 / Canola 01/ Wheat 02

Paddock Standard fertilizer: 100kg Agrich + 90 Urea

Treatments:

The first to treatments of the trial investigate the theory that wheat crops grown on deep week sands perform better if sown with a low seed rate.

The remaining treatments investigate the responsiveness of wheat to N, P and K on each productivity zone.

Nitrogen and Potassium treatments
The soil tests indicated that some sites in the paddock were marginal for potassium (site D,E,G,H)

The nitrogen rates have been determined assuming the following estimated yields in each zone.

Measurement of response.
The trial paddock will be flown over by Air Agronomics (2M resolution) to give indication of biomass response to phosphate, nitrogen and potash.

Plots will be harvested according to production zone with a weight trailer at harvest and utilising yield mapping technology.
