A Resilient Barossa Landscape

Healthy soil, less water use, no cultivation = a resilient Barossa landscape: By the time the 2017 vintage is over, Barossa grower Warwick Murray will have spread 3000 tonnes of wine grape stalks on local vineyards.
Why? Over five years, stalks have contributed to the soil organic carbon levels increasing from 0.3 to 1.65 on his Vine Vale vineyard. His vines are healthy and green after minimal irrigation this growing season.

This locally-sourced woody waste breaks down and turn into “humus” which increases the bulk density of the soil, and contributes to moisture and nutrient retention. Warwick continues to monitor potassium levels, which have not increased significantly in five years.
