Effect of fertiliser sown with wheat seed on Mallee soils locations
Aims

There are major opportunities to improve crop performance on Mallee sands, opportunities to invest in the transformation of poor sands and opportunities to improve yield through more targeted agronomy of sandy soils. In 2015 wheat plant establishment was significantly better on non-wetting sand (crest and dune) plots that received no fertiliser with the seed compared with those that received 50 kg DAP/ha. Similar effects were measured in trials established by Jack Desbiolles at Moorlands in 2015 (McBeath et al. 2016).

Key messages
  • Just 50 kg DAP/ha knife point drilled with 70 kg/ha wheat seed is enough to reduce wheat plant  establishment.
  • Wheat fertilised with DAP with seed yielded 0.5 t/ha (20%) less than wheat with DAP placed below seed in 2016.
  • The addition of 35 kg urea/ha below the seed overcame the yield penalty in the DAP-with-seed plots, suggesting access to N was a driver.

Karoonda 2016

Sowing machinery

28 cm row spacing.

The trial was established using knife points and a dual shoot system.

Sow date 2 June 2016
Harvest date Not specified
Plot size Not specified
Plot replication Not specified
Fertiliser

All plots received a pre-sowing application of 33 kg/ha of potassium sulfate to eliminate K and S as confounding issues with an in-crop foliar application of Zn, Cu and Mn. Fertiliser placed below the seed was approximately 5cm below seeding depth.
