What Makes Magnesium Chloride an Effective Source of Magnesium for Plants and Industry?
Technical Introduction
Magnesium chloride (MgCl₂) is a white to colorless crystalline salt that is highly water-soluble.
It provides magnesium (Mg), an essential nutrient for chlorophyll synthesis, enzyme activation, and plant metabolism, and chloride (Cl), which is beneficial for some crops in small amounts.
Magnesium chloride is used in agriculture, aquaculture, food processing, and chemical industries.
Applications
1. Agriculture & Horticulture
Micronutrient Fertilizer: Corrects magnesium deficiencies in crops like vegetables, cereals, and fruits.
Foliar Spray: Rapidly provides magnesium to plants for improved chlorophyll content and photosynthesis.
Soil Amendment: Enhances magnesium availability in sandy or magnesium-deficient soils.
2. Industrial Uses
De-icing Agent: Used for roads and pavements in winter conditions.
Dust Control: Stabilizes soil and reduces airborne dust.
Chemical Manufacturing: Precursor in production of magnesium-based chemicals.
3. Other Uses
Food Industry: As a firming agent and electrolyte supplement.
Aquaculture: Provides magnesium for aquatic organisms.
Advantages
Highly Soluble: Fast-acting source of magnesium.
Dual Nutrient Source: Supplies both magnesium and chloride.
Versatile Applications: Useful in agriculture, industry, and food processing.
Stable and Easy to Handle: Long shelf life when stored properly.

FAQs
Q1: How is magnesium chloride different from magnesium sulfate?
A1: MgCl₂ provides magnesium and chloride, while MgSO₄ provides magnesium and sulfur; MgCl₂ is often more soluble.
Q2: Can it be used as a foliar spray?
A2: Yes, typically in diluted form (0.5–1%) to avoid leaf burn.
Q3: Is magnesium chloride safe for crops and animals?
A3: Yes, when applied at recommended levels; excessive chloride can be harmful.
Q4: How quickly does it correct magnesium deficiency?
A4: Foliar applications show results within a few days; soil applications may take a week or more.
Q5: How should it be stored?
A5: Keep in a dry, sealed, and ventilated area to prevent moisture absorption and caking.
