Magnesium plays a central role in photosynthesis, as its atom is present at the center of each chlorophyll molecule.
It is also involved in several key steps in the production of sugar and protein, as well as the transport of sugars in the form of sucrose from the leaves to the tubers.
Deficiency – Leaves turn yellow and brown, leaves wither and die. Stunted plants, early maturation of the crop. Poor skin finish on the tubers. Deficiency results in reduced tuber formation and lower yields. Magnesium-deficient tubers are more easily damaged during lifting and storage.
