GEOCHEMISTRY OF VINEYARD SOILS - ADELAIDE PLAINS / WILLUNGA BASIN

Registration Closes October 9, 2024

Mid-conference Full-day field trip (16 October 2024)

Geochemistry of Vineyard Soils on the Adelaide Plains and Willunga Basin, SA

This vineyard field soil tour will relate the soil geochemistry in vineyards by exploring the region through the lens of vineyards planted and wine making on the Adelaide plains (1992 Coombe vineyard, Waite Campus) and Willunga Basin (1897 Slate Creek vineyard in Willunga) to highlight and explain:

· The genesis of sharp boundaries between red and/or calcareous horizons

· Grape production and soil carbon sequestration

· Irrigation water salinity

· Na and Cl concentrations in berry juice of vines

· Wine quality (Na and Cl are below international maximum allowable limits) by wine tasting at the Chalk Hill Wines, Cellar Door: Chalk Hill Wines

Besides learning about the soils’ geochemistry, delegates will have a chance to taste and purchase some great wines from two of the region’s best known vineyards, Chalk Hill Wines (McLaren Vale) and Slate Creek Vineyard (Willunga). You will also learn more about the age old debate about how important (or not) the soil (or, as the French would say, the ‘terroir’) is for making a great wine.

Rob Fitzpatrick (CSIRO) will be the guide for the day.
