Deep ripping and deep placement of lime locations
Aims

To improve grain production by ameliorating subsurface compaction and subsurface acidity.

Key messages

This work has demonstrated that it is possible to incorporate lime into seams in the soil profiel which can increase the soil pH and decrease the levels of toxic aluminium.
