It occurs relatively frequently in the earth's crust, but not in its pure form (solid), but only in ores. The most important ores for zinc production are zinc sulfide ores. Zinc is essential for all living things and is an important component enzymes, For healthy growth of the vine it is very important. Zinc deficiency is particularly common in sandy soils. Are also at risk floors with extremely high content of phosphorus, because an increased supply of phosphorus to the vine can hinder zinc absorption.

Likewise, lime-rich soils or high content tend to calcium to zinc deficiency. This leads to disturbances in the blossom and in fruit set, poorly woody stem frames and poorly developed exaggerated, The leaves have sharp serrated edges and open stem bays with elongated, narrow leaves. This often goes hand in hand chlorosis, Treatment is carried out by brushing pruning wounds with zinc paste or by spraying the foliage. The use of galvanized wire and stickel in the vineyard can lead to large excess in the soil. Too high a content in the wine leads to cloudiness and metallic - bitter Taste.
