To demonstrate the soil health and crop growth benefits of using soil ameliorants combined with cultivation to depth to address subsoil aluminium toxicity. To increase awareness and support the adoption of tools and methods to identify and effectively manage aluminium toxicity
• Soil sampling to depth identified that Aluminium (Al) toxicity was present as a soil health and crop growth constraint.
• All amelioration techniques of subsoil aluminium toxicity had a positive yield response.
• The ameliorant treatments did not show a net positive effect on the enterprise earnings in the first year.
• The biochar treatments had significantly higher plant numbers than the lime or gypsum treatments but significantly lower yields.
• The untreated control had higher crop and lower weed numbers than any other treatment but significantly lower yield.
