Subsoil amelioration in pasture systems locations
Aims

To trial the sub soil treatment of ripping and adding a soil ameliorant in a lucerne pasture.

Key messages
  • PPS believes that the results in the Jallukar trial show that the technique of sub soil amelioration has potential to produce large increases in productivity in certain soils in the Upper Wimmera region.  
  • The drier than average springs allowed for only one dry matter cut each year; more favourable seasons may have altered the results. 
  • For further discussion please see the attached trial report.
