Join us for a field walk at the Accolade Vineyard in Padthaway.  This incubator project is near completion and this is an opportunity to walk the mulched row and ask questions.

Phylloxera footbaths and Covid protocols will be in place.  Bus into the vineyard will be provided.

Abstract
This trial was conducted to better understand how non-standard weed management practices (such as mulching, compost with mulch and mechanical weeding) compare to undervine herbicide application in Padthaway, South Australia. Across the 2020, vintage soil physicochemical properties, leaf blade nutrient composition, plant available nitrogen and yields were quantified. Results showed that immediate changes in canopy size (leaf area) were detectable, berry juice pH was significantly lower, titratable acidity and yeast assimilable nitrogen significantly higher for the mulch and compost treatment than for other treatments. These effects might be explained by significant increases in soil and leaf nitrogen or phosphorous, or significant differences in soil moisture.
