Phosphorous is absorbed as phosphates which is an important constituent of the cell membrane, proteins. Also, phosphorus is necessary for the phosphorylation process. Deficiency leads to abnormal discolouration of the plant parts. Calcium is an important constituent required by meristematic and differentiating tissues. Calcium deficiency leads to localized necrosis and stunted growth.

Copper occurs in almost every type of soil in the form of complex organic compounds. It helps in activating many enzymes and part of plastocyanin. Plastocyanin is important for photophosphorylation process. Its deficiency reduces the growth in plant.
