To quantify the yield limitation caused by subsoil acidity and evaluate innovative soil amendments that act to ameliorate subsurface acidity.
• Deep placement of soil ameliorants applied during 2017 continued to improve soil pH and decreased aluminium (Al) concentrations in the subsurface soil layer during 2019.
• The benefits of soil amendments to soil pH and aluminium concentration remain for future seasons.
• Grain protein increased in treatments that ameliorated acidity and increased soil nutrition.
