Magnesium is required by all crops to capture the sun's energy for growth and production through photosynthesis. Photosynthesis occurs in chlorophyll, the green pigment in plants, and magnesium is the central atom of the chlorophyll molecule, with each molecule containing 6.7% magnesium.

Magnesium plays an important role in activating enzymes involved in respiration, photosynthesis and nucleic acid synthesis. It aids in phosphate metabolism, serving as a carrier of phosphate compounds through the plant. Magnesium facilitates translocation of carbohydrates (sugars and starches) and enhances the production of oils and fats.

Deficiency symptoms: Older leaves show interveinal chlorosis (dark green veins with yellow areas between them). Chlorotic leaves develop spotted necrotic areas and their margins curl. Since Mg is mobile in the plant, the bottom leaves are always affected first.

Fertilizer sources:  quicK-Mg is a granular, fully soluble, white natural fertilizer containing both potassium and magnesium ( 0-0-15-13 MgO). quicK-Mg is completely soluble in water, thus ensuring full availability of K and Mg to the plant. It is suitable for direct application to the soil and for fertigation, as a source of K and Mg in liquid fertilizers. quicK-Mg is derived from the natural minerals of the Dead Sea, which are rich in magnesium and potassium. It is produced and marketed by ICL Fertilizers' specialties business unit, ICL Specialty Fertilizers.
