Bluish-white, brittle heavy metal or trace element (Zn). The name is derived from Zinke (tooth, prong), as zinc solidifies in a prong shape. It occurs relatively frequently in the earth's crust, but not in pure form (native), but only bound in various ores. The most important ores for zinc production are zinc sulphide ores such as sphalerite or wurtzite. Zinc is essential for all living organisms and is a component of important enzymes. The element is of great importance for the healthy growth of the vine. Zinc deficiency is particularly prevalent in sandy soils. Soils with an extremely high phosphorus content are also at risk, as an increased phosphorus supply to the vine can hinder zinc absorption.
