Irrigation Discussion Group Focus Paddock - Deep ripping to increase access to stored soil moisture locations
Aims

The aim of the focus paddock was to see if deep ripping could increase plant avaliable water by removing any compaction and allowing roots to access stored moisture deeper into the soil profile.

Key messages

Key learning from this focus paddock was you can’t fix a chemical problem with a physical solution. We need to invest the time and money in investigating the problem and understanding the soil constraints present in the paddock before investing in solutions. Sodicity was an issue and should be the first problem addressed when trying to improve the performance of soils within the paddock.

Trial treatments:

  1. Untreated
  2. Ripped

The ripper was TTQ Raptor with 9 tynes spaced at 600 mm with a tow behind steel crumble roller. Tractor was a Case Steiger 500 Hp. Ripping speed was 4 KPH (at 450mm depth) and the fuel consumption was 96 Lts/Hr. Coverage rate was about 2.1 Ha/Hr.
