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.
Take home messages from the paper include:
- Lime is the most effective ameliorant to increase soil pH
- Organic materials are not as effective as lime in changing pH, but reduced exchangeable Al% significantly
- Applying lime with organic materials could facilitate downward movement of alkalinity
- However, over a longer term applying large amounts of organic materials could acidify soil due to nitrification.
