Join soil productivity research officer Wayne Parker live on Friday 24 November from 12-12.30pm as he delivers Decreasing subsoil constraints with topsoil slotting plates.

Subsoil compaction induced by machinery traffic reduces root growth, rooting depth and limits access to moisture and nutrients.
Around 70% of soils in the Western Australian wheatbelt have a moderate to high risk of subsoil compaction.
Deep ripping with tined implements is the most common way growers rectify subsoil compaction.
A deep ripper was specifically constructed to investigate ripping below 450mm and used in eight trials, at six sites across WA.
Results over two years indicate that topsoil slotting plates add to the yield response from deep ripping and provide at least two years of continued positive response in a range of soil types.
