The silver-white, soft light metal (Ca = calcium) is the third most abundant metal or the fifth most abundant element of the earth's crust after iron and aluminum. Due to its reactivity, it occurs only chemically bound in over 700 minerals mostly as carbonate, fluorite or sulfate. Calcium-containing minerals such as basalt, dionite, calcite, chalk, gypsum, granite, marble and marl are present in large quantities, the Alps are predominantly made of limestone. As an essential component of living matter, it plays a key role in building leaves, shells, bones and teeth. Due to the frequency it is rare to deficiency symptoms. The carbonates are predominantly the remains of marine life (corals, shells, snails) that have accumulated over millions of years.

Calcium is considered one of the most important nutrient for the growth of vine of great importance. It strengthens the cell wall structure, activates numerous enzymes and prevents the penetration of harmful berries microorganisms, In the vineyard calcium provides positive for an optimal water discharge or the discharge of excess water. In addition, the availability of other nutrients for the vine is improved. An excess of calcium promotes the appearance of chlorosis, to an extreme extent, it is negative for viticulture. Too little proportion causes low-acid soils PH value, This is especially true in high rainfall Areas and affects root growth. At pH values below 5.9 is one fertilization (Calcification) recommended. Calcium and magnesium have partly the same functions in the nutrient supply of the plants and can replace each other to a certain extent. In wine it may be due to the formation of Weinstein come to calcium opacities. See also about limestone or limestone soil type,
