Demonstrating management options for water repellent soils (Corrigin) locations
Aims

To demonstrate various long and short-term management options to mitigate water repellent soils in the Corrigin area in 2017

Key messages

A demonstration to showcase options for managing water repellent soils was established in 2017. Mace wheat was sown into sand over gravel (below 20cm) on 24 May following 209mm summer rain, with no rain in April and 14mm in May.

  • One-way plough reduced subsoil compaction to 30cm depth and improved soil wettability, crop establishment and yield.
  • Deep ripping reduced compaction to 30 cm depth, improved crop establishment and yield, but not soil wettability.
  • Knife point sowing established and yielded better than the splitter boot when sowing on deep ripped and one-way ploughed plots.
