1 Monitoring and Meeting Wine Grape Mineral Nutrition Needs in Santa Cruz Districts Peter Christensen Viticulture Specialist, Emeritus Department of Viticulture and Enology University of California, Davis
2 Mineral Nutrient Deficiencies and Excesses in Grapes Macronutrients Nitrogen Potassium Phosphorus Magnesium Calcium Sulfur Micronutrients Zinc Boron Iron Manganese Copper Molybdenum
3 Monitoring Mineral Nutrition Knowledge of: Site/Soil characteristics and chemistry Vineyard design requirements Fertilizer inputs Cultural practices Tissue analysis Observation and judgment
4 SOIL CHEMICAL ANALYSIS ph - Salinity - Permeability - Toxicity - Cation Exchange - Acidity and alkalinity Potassium Calcium Magnesium
5 SOIL CHEMICAL ANALYSIS -- OTHER Amending Baseline nutrient levels Lime or gypsum requirement Background information and awareness

72 BORON APPLICATION WITH DRIP IRRIGATION Vine uptake of drip-applied B is rapid. 1-lb B/acre can be safely applied to mature vines with single application. Equivalent to 5 lbs 20.5% B product Annual application of 1-lb 1 B per acre applied for 3 or 4 years may be excessive. For maintenance, apply ½ lb B every year. B can be applied any time of year. Monitor with tissue analysis.
73 BORON FOLIAR SPRAY Fall sprays Increase B content of dormant bud tissue. Most effective in eliminating fruit symptoms. Leaves are more tolerant of applied B. Single application of 1 lb B/acre can be used. Pre-bloom and bloom sprays Only 1/2 B/acre is safe with each application Only partially effective in preventing fruit symptoms
