Used in agriculture as a foliar spray to correct magnesium deficiency in plants, improving chlorophyll production and overall plant health. Commonly applied in crop farming, horticulture, and turf management to prevent yellowing of leaves (interveinal chlorosis). Also utilized in fertigation systems to supply magnesium in hydroponic and soilless growing setups. In industrial settings, serves as a component in water treatment and boiler feedwater to control scaling and corrosion. Occasionally used in pharmaceuticals and dietary supplements as a source of bioavailable magnesium.
