• calcium and sulphur are present in structural components. When there is deficiency of these elements its not possible to break the structures i.e. these are immobile... Thus calcium as well as sulphur remain in old leaves

• Calcium occurs throughout the entire plant. It is used for many of the life processes in the plant; however, calcium is most important for the growth process. It has a regulating effect in the cells and contributes to the stability of the plant..Since calcium can be transported almost exclusively through the xylem vessels, it is an element that possesses little mobility within the plant. It is, therefore, important that a sufficient amount of calcium is always available in the root environment, so that it will be continuously available for absorption by the plant....
