INVESTIGATING ACIDITY IN SUB-SURFACE SOILS
Father and son duo Neil and Charlie Vallance are farming in the high rainfall, high yielding region of Western Victoria. Purchasing this farm in April 2018, it was previously managed as an Australian phalaris pasture system with no history of lime addition for pH management or fertiliser inputs.
Following on from surface lime applications in 2018, Neil and Charlie wanted to investigate potential variation in pH down through the soil profile, in particular what was happing in the sub-surface layers.
