Hear from leading experts on the cause and effect of soil acidity, soil pH mapping and NDVI, lime sources and application rates, recent research results from current lime trials across SA and on-farm decision support models.

About the project:Acid Soils SA is a collaborative project which provides resources, information and research updates to underpin best practice surface and subsurface soil acidity management in South Australia.

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.

SOIL ACIDITY AND LIMING WORKSHOPS

A free half-day workshop providing growers and advisers with information, resources and tools to improve the management of surface and subsurface soil acidity in South Australia.
