The growth and development of a grapevine depends on the circulation of nutrients through the plant. Sap transports water, sugars, metabolites and mineral elements to the organs that need them.

Plantsap analysis provides direct insight into this circulation and helps optimise vine nutrition during the entire crop cycle.

It is a sap analysis developed specifically for viticulture. It measures the composition of vine sap to reveal nutrient uptake, balance and mobility.

Unlike leaf or soil analyses, sap analysis provides a real-time picture of the plant’s physiological state.

Vines have fluctuating nutritional needs depending on growth stage, weather, fruit load and variety. Plantsap analysis helps growers understand these dynamics and adjust fertilisation before problems become visible.

Sap analysis supports:

• Stable vegetative growth
• Stress reduction
• Improved grape quality
• Targeted adjustments throughout the season

Using plantsap analysis, you can:

• Anticipate deficiencies or excesses through real-time monitoring
• Strengthen the plant’s natural defences
• Optimise vine nutrition during key stages
• Avoid unnecessary fertiliser costs and environmental losses
• Assess the behaviour of new varieties in trials
• Evaluate fertilisation strategies under controlled conditions

Plantsap analysis is suitable when:

• Fast nutritional feedback is needed during critical phenological stages
• Vines show early signs of imbalance or stress
• Comparing vineyards, blocks or new cultivars
• Monitoring high-demand crops with variable nutrient needs
• Testing the impact of different fertilisation programs
