The take home messages from this GRDC funded research are below. Please access the full paper via the link below for methodology, references, acknowledgements and discussion.
Key messages from the paper include:
- Mechanical lime incorporation, using tillage implements suitable for the soil type, enables subsoil acidity to be improved at a faster rate than simply surface application.
- Tillage also addresses other soil constraints and improves crop yield, particularly in the first year on deep sands in medium to high rainfall areas.
- In low rainfall areas on gravel soil and red loam the best return on investment was lime only.
