Find Yara advice on all grape and grapevine crop nutrition issues

High grapevine yields are obtained on the most freely drained soils where water is not limiting. Vines will grow across a wide range of soil pHs, but extremes will render many nutrients unavailable and thereby restrict yield.

Role of nutrients in grapevines by growth stage

Grapevine nutrient requirements vary depending on the crop growth stage. Find out which nutrients are most important and the roles of nutrients at different grape growth stages.

Improving grape quality

The aim of any grower is a high yielding, top quality wine grape that satisfies the wine-maker. Both yield and quality are strongly influenced by nutrition.

Influencing grape and wine pH

Strong vine canopies can lead to excessive nitrogen and potassium uptake, which increases grape and wine pH.

Grapevine nutritional summary

A deficiency of any single nutrient is enough to limit grape yield or affect grape quality so the availability of each nutrient needs to be related to the crop requirements.

Influencing total acidity in grapevines

A certain level of acidity is considered important to the taste of any wine. This can be influenced by crop nutrition
