Vineyards, Reduce Inputs, Enhance Output – Spain

A renowned vineyard in the Ribera del Duero region in Spain conducted a two-year trial with OCC on the Tempranillo variety in 2014 and 2015. The viticulturist applied three applications in both campaigns to compare the efficacy of colloidal protocol against the vineyard’s standard protocol; At 20-40cm sprouting, at the start of flowering, and around 50% veraison. In addition, the vineyard combines nutritional and protection spray in the same tank mix to reduce the application cost.  Results showed OCC improved 25% yields in both campaigns despite a 30% reduction in nutrients and chemical input over two harvests.
