To explore the effects of nitrogen, sulfur and zinc on wheat productivity. The treatments included a range of N, S and Zn based treatments which were designed to address whether;
1) Constraints to productivity on sands could be managed by manipulating the nutrition package,
2) Early application of N is the most profitable option,
3) Zn is a constraint to yield and if the source of Zn is important, and
4) S is a constraint to yield and if the source of S is important.

Fertiliser |
All plots received 50 kg/ha of single super phosphate. The rate x timing trial also received a pre-sowing application of 33 kg/ha of potassium sulfate to eliminate K and S and foliar applications of Zn, Mn and Cu. The fertiliser source trial received a foliar application Mn and Cu only |
