There are more than 2 million hectares of non-wetting sandy soils in western and southern Australia. Water repellency in soils causes uneven water infiltration, poor crop and pasture germination and leaves the soil prone to wind and water erosion. This also causes poor weed resistance, exacerbating herbicide resistance, and also leads to inefficient nutrient use in cropping and pasture systems.
Non-wetting soils are a significant constraint in the Corrigin area, with water repellence resulting in poor germination of crops and pastures. The Corrigin Farm Improvement Group (CFIG) has identified non-wetting soil as a major issue for their members and have been exploring cost effective ways growers are able to manage these soil to reduce water repellence and improve crop and pasture vigor.
There are a number of treatment options for non-wetting soils, with mechanical techniques and soil wetters achieving good results in a number of trials elsewhere in the Wheatbelt. This project will specifically examine 5 treatments for non-wetting soils, including:
- One way disc plough
- Bi-Agra Band wetter agent
- SE14 SACOA wetter agent
- 90mm knife points
Project outputs will be added once the trial has been completed.
