Sustainable Winegrowing With Vineyard Team

The health of a grapevine starts at ground level – literally in the soil. The California Department of Food and Agriculture is helping farmers improve the quality of their soils through the Healthy Soils Initiative. Taylor Jones, Ph.D., Director of Viticulture at Star Lane and Dierberg Vineyards used his funding as an opportunity to study the effects of compost. After completing two three-year trials in six different soil types in two American Viticulture Areas, Taylor found that compost additions significantly increased organic matter, Reduced Nitrogen, Phosphorous, and Potassium usage by 35 percent, and decreased water use dramatically. Listen in to hear the only downside to increasing the use of compost on your vineyard.
