Non-wetting and compacting soils grower case study
Description
Esperance-based grower Gavin Egan started using clay spreading, delving and deep ripping to ameliorate soil water repellence and compaction issues seven years ago. For Gavin, the results have paid off.
What was typical Western Australian flat Mallee country, producing around 2t/ha cereal crops, is now delivering double those yields. This topic was the focus of the GRDC investment Soil Constraints West project.
The project is a collaboration between the GRDC and the Department of Primary Industries and Regional Development, and aims to help improve soil constraints and lift yields and grain grower returns.
