Calcium participates in the synthesis of proteins, development of roots, constitution of cell membranes… .it is considered a quality element.
It is the dominant element of the intracellular buffering power, regulating the pH of the cellular juice.
Calcium Deficiency or Lack:
Symptoms of calcium deficiencies are manifested in the youngest leaves with internervial chlorosis that can end in necrosis first at the edges and then between the nerves.

The symptoms are those associated with these deficiencies.
