Deep ripping work to date on farm and in other regions of the Wheatbelt has shown very positive results. It appears ripping with inclusion plates is incorporating lime to depth and allowing plants to penetrate deeper into the soil profile. This allows the plants to access nutrients and water that would be otherwise unavailable to plants, reducing the need for energy hungry fertilisers.
While deep ripping with inclusion plates is not innovative per se, its usefulness for much of the Wheatbelt region is unknown and most profitable ripping depth, unclear. The innovative aspect of this project is that the deep ripping will be conducted down to 700mm and investigated on three different soil types typical to the Wheatbelt region to determine which soil types are most responsive to ripping at this depth.
The aim of this project is to quantify the crop yield benefits and nutrient recovery and water use efficiency improvements from deep ripping with inclusion plates down to 700mm across three different typical Wheatbelt soil types.
