In this episode of the MSF FarmTalk podcast, host Kylie Matthewson discusses the issue of acid soils affecting farms in the Mallee region with David Woodard, a soils consultant from Primary Industries and Regions in South Australia.

They explore how acid soils impact productivity, the use of gypsum and lime in soil treatment, and the different results from long-term soil trials at Lameroo. David goes through the benefits of early action, how higher lime rates and clay spreading can effectively manage soil pH levels, and addresses the challenges posed by rising input costs and dry seasons.

David also shares where listeners can find more information about these long-term lime trials and their results.
