Can your soil hold enough water to carry vines through the season without irrigation? Miguel Garcia, Regenative Agriculture Project Manager at Napa RCD, shares findings from a 15-vineyard study across California's North Coast. By measuring organic matter, soil respiration, active carbon, and aggregate stability, the project evaluates how soils store and supply water over the growing season. Learn how cover crops, tillage practices, and deep root systems shape soil and moisture dynamics, and how dry-farmed vineyards compare with the broader soil health database.
