Canola responds to amelioration of water repellant and acidic yellow sand using soil inversion and lime locations
Aims

To demonstrate how soil inversion using a mouldbaord plough could be used to incorporate lime into acidic subsoil, overcome soil water repellance and control weeds and to measure its in=mpact and growth.

Key messages
  • Subsoil acidity, topsoil water repellance and herbicide resistance weeds are often found in combination on sandplain soils in Western Australian wheatbelt.
  • One-off mouldboard ploughing is being investigated as a way to decimate herbicide resistant weed seed banks. bury water repellant top soil and incorporate lime into into acid subsoils.
