This product contains 10% MgO. One of the indispensable elements in the entire BIO NOVA fertilizer line is magnesium. Magnesium forms the reactive core of chlorophyll, which converts light energy into chemical energy (ATP and ADP).

Magnesium deficiency manifests itself in chlorosis (slight discoloration) between the veins of old leaves and also as early leaf drop.

Excess results in diseased growth and small leaves.
