Effect of nitrogen and copper fertiliser on wheat grown  on yellow-brown gravelly sand of Newdegate Research Station locations
Aims

To measure the effects rates of nitrogen on copper availability for maximum grain yield of wheat grown on  yellow sandy soils  across  seasons.

Key messages
  • Summary of  2 experiments

  • Soil extractable Cu was 0.23 mg/kg.

  • Plant density were not effected by Cu or N fertiliser (29-36 plants/m of row2)
  • Plant B concentrations 26 -30 mg/kg.

  • Cu fertiliser had no effect on seedling density; September Dry matter (DM) (2.0 t/ha); Seed yield (1.55 t/ha) or N % in DM (3.43 % N) or N in the seed (3.6 %).

  • B had no effect on %oil (41.9) or on oil yield (650 kg/ha).

  • Soil extractable B Hot CaCl2 of 0.7 was adequate

    Care needs to be taken on use of borax fertilizer as toxicity was induced in canola with 0.34 to 1 kg B ha−1(3-10 kg borax ha−1) at sowing depressing seed yield, mostly by decreasing plant density. Rather than making general recommendation for B fertilizer application based on 0.01M CaCl2 soil extractable B, soil and plant analysis should be used to diagnose B deficiency and B fertilizer use limited to calcium borate or foliar borax rather than soil-applied borax on low B sands.
