To address the problem of subsoil acidification, a long-term field experiment was established in 2016. The objectives were to:
• manage subsurface soil acidity through innovative amelioration methods that will increase productivity, profitability and sustainability
• study soil processes, such as changes in soil chemical, physical and biological properties over the long term.
• Lime is the most effective amendment to increase pH and reduce exchangeable aluminium (Al).
• Deep placement of organic materials had a limited effect on soil pH, but reduced exchangeable aluminium percentage (Al%) significantly.
• The combination of lime with organic materials could facilitate alkalinity downwards in the soil profile in the short term.
• However, applying a large amount of organic materials could acidify soil over a longer term due to nitrification.
• No crop response was observed over the past three years due to severe drought conditions.
