Over the last decade, grape growers in SE South Australia have had their water entitlements converted to volumetric allocations, experienced a reduction in annual rainfall and seen a rise in the salinity of groundwater which is used for irrigation. Irrigators have moved away from flood and sprinkler irrigation, which was still widely used in the last decade of the 20th century, to precision irrigation applied with drippers. Annual application rates have decreased from between 4 and 6 ML/ha down to 2 or less ML/ha. In middle of the first decade in the 21st century, salinity damage was emerging in some vineyards. In response the Limestone Coast Wine Industry Council convened a Root Zone Salinity Workshop in May 2006 at Padthaway. The current project addresses concerns raised following this workshop
