By oxidation luminous element (P), whose name is derived from Phosphoros (Greek light bearer). In nature, it is exclusively bound mostly in the form of phosphates. Typical minerals are apatite, phosphorite, turquoise and wavelellite. It is also contained in guano (bird droppings) and is used as fertilizer in this form. Pure, white phosphorus produces corrosive wounds and is very toxic, even 50 mg are deadly to humans. Phosphorus compounds are essential for all living things and in central areas like the DNA involved as a component of nucleic acids and cellular energy supply. In the metabolism of the vine phosphor fulfills many functions. It plays a central role in the energy budget, in which photosynthesis and as a component of proteins and enzymes. The proportion in the pits is particularly high. Very simply, one can express that phosphorus is mainly the Blossoms- and fruiting serves.

In strongly acidic and even alkaline soils, phosphorus can be fixed (bound) and is thus no longer available to plants. A phosphorus deficiency manifests itself in the vine by bluish green to purple discoloration of the leaves as well as weak flower and fruit formation. Most of the vineyards have been receiving large quantities of phosphorus fertilizers since the end of the 19th century. A deficient provision of the vine is therefore not fundamentally a defect in the ground but often due to low availability. The phosphates tend to form compounds which are difficult to dissolve and thus difficult to obtain. Only a small proportion of the phosphorus in the soil is present in water soluble absorbable form. A fertilization using phosphates must therefore depend exactly on the soil PH value be matched. Phosphates are also called insecticides used for pest control.
