The aim of this research was to quantify the yield limitation caused by subsoil acidity and evaluate innovative soil amendments which act to ameliorate subsurface acidity.
• Large farm-scale trials provided useful practical information about applying soil amendments to relate back to small-scale and glasshouse-based experiments.
• Triticale showed a limited response to lime application at the Rutherglen site during 2019, most likely due to its tolerance to acid soils.
• During 2019, canola establishment at the Bungeet site was compromised by a lack of rainfall between deep ripping and sowing, followed by an intense rainfall event, leading to uneven germination.
• Assessment of subsoil amelioration techniques is difficult due to confounding factors, with several years of data collection required to allow for the physical effects of deep ripping to subside.
