Managing subsoil acidity – project overview locations
Aims

The aim of the project is to manage subsoil acidity through innovative amelioration methods that increase productivity, profitability and sustainability on farms.

Key messages

• Subsoil acidity is a major constraint to crop productivity in the high rainfall zone (500–800 mm) of southeastern Australia.
• More aggressive methods, such as deep ripping in conjunction with lime or other amendments, are being tested to achieve rapid changes to pH at depth.
• A long-term field experiment was established to study changes in the chemical, physical and biological properties of soil under vigorous soil amelioration techniques.
