To determine if the addition of lime and its method of incorporation (mouldboard ploughing or deep ripping) has an effect on the soil pH profile, topsoil water repellence and crop productivity.
As canola has the ability to compensate for bare areas by closing over the canopy, it is likely that if the trial area was planted to cereals, the variation between yields may have been greater. Over the first three seasons there have not been significant yield responses to the tillage treatments. Establishment on the mouldboard plough areas has been poor and this may be related to herbicide damage but weed control on the ploughed areas has been improved. Monitoring of this trial is ongoing, to see the impact of the treatments over time.
