Nutrient management is one of many cultural practices used to balance vine growth and fruiting, and to achieve optimum grape production and quality.  Soil testing is a recommended procedure to determine what soil amendments might be needed prior to planting a vineyard.  Once in production, growers should use tissue analysis to assess the nutritional status of their vines prior to nutrient supplementation.  This webinar will cover basic procedures for collecting both soil and petiole samples, and interpretation of the results.
