ACID SOILS
SOUTHERN REGION
Providing growers and advisers with information, resources and tools to improve the management of surface and subsurface soil acidity in the southern region.
Acid Soils Southern Region is a collaborative project which provides resources, information and research updates to underpin best practice surface and subsurface soil acidity management in South Australia, Victoria and Tasmania.
The project will generate new information regarding lime movement and effectiveness when applied to the surface of different soils and environments in modern farming systems. It will also work to identify, develop and validate novel acidity management practices such as lime forms, placement and incorporation methods, such as spading or topsoil slotting.

RESOURCES
Careful management of soil acidity can produce great cost savings for growers in the short and medium term.
Click through our tools, resources and information to better diagnose and manage soil acidity. While most resources are designed for grain growers (cereals/pulses/oilseeds), information and tools are applicable to grazing and horticultural enterprises.
Project Partners
The GRDC Acid Soils - Southern Region project, titled NGN Innovative Solutions to Subsurface Acidity, is a Grains Research and Development Corporation (GRDC) investment to extend results and findings from preceding GRDC investments into acid soils in the Southern Region (UOA1905-015RTX, UOA2206-009RTX) and brings together project partners from South Australia’s Department of Primary Industries and Regions, the South Australian Department for Environment and Water, and AgCommunicators. (GRDC Project Code: DAS2512-003RTX).
