Almost six million hectares of WA's sand-plain soils in the medium and high-rainfall zones feature multiple constraints, including water repellence, acidity, and compaction. An estimated 250,000 hectares of those six million have been ameliorated, typically involving strategic one-off deep tillage. A GRDC investment is helping to determine the longevity benefits following soil amelioration, looking at crop rotations, species choice and seedbed preparation. We hear from Dr. Stephen Davies from WA's Department of Primary Industries and Regional Development, on the project's initial findings.
