Plant Nutrition

Magnesium is an essential element for plant growth, as the central core of the chlorophyll molecule in plant tissue. If a plant is Mg deficient, the shortage of chlorophyll results in poor and stunted plant growth. Magnesium also helps to activate specific enzyme systems. Enzymes are complex substances that build, modify, or break down compounds as part of a plant's normal metabolism.
