Zinc is essential for all living beings and is a component of important enzymes, For a healthy growth of the vine he has great importance. A zinc deficiency occurs mainly in sandy soil. Furthermore endangered are soils with an extremely high content of phosphorus because increased phosphorus supply to the vine can hinder zinc uptake.

Likewise calcareous soils or high content tend calcium to zinc deficiency. This leads to disturbances in the blossom and in fruit set, poorly lignified stems and poorly developed exaggerated, The leaves have sharply toothed edges and open stalk pens.
