Description
Magnesium Sulphate (Green OK) Food grade | 25kg is a high-quality, water-soluble compound used primarily in agriculture, horticulture, and sometimes in industrial or food applications (depending on grade). It provides two essential nutrients: magnesium (Mg) and sulfur (S), which play vital roles in plant growth and crop productivity.
It is typically supplied as Magnesium Sulphate Heptahydrate (MgSO₄·7H₂O) in crystalline form and is known for its high solubility, ease of use, and compatibility with other fertilizers.
Magnesium Sulphate (Green OK) Food grade | 25kg is designed for use as a magnesium supplement in the food and beverage industry, brewing, baking, food preservation, nutraceuticals, and mineral water processing. It is an odorless, white crystalline powder that dissolves easily in water.
Features of Magnesium Sulphate (Green OK) Food grade | 25kg:
Contains Essential Nutrients:
-
-
Magnesium (Mg): 9.5–10%
-
Sulfur (S): 12–13% (as SO₄²⁻)
-
Water Soluble: Fully soluble in water ideal for fertigation, foliar spraying, and hydroponics.
Free-Flowing Crystals: Easy to apply, store, and mix with other fertilizers.
Improves Plant Health: Boosts chlorophyll production, photosynthesis, nutrient uptake, and protein synthesis.
Neutral pH: Does not affect soil acidity or alkalinity.
Applications in Agriculture:
| Crop Type | Role of MgSO₄ |
|---|---|
| Vegetables | Improves leaf color, prevents interveinal chlorosis |
| Fruits (e.g., citrus, mango) | Enhances fruit set and sugar accumulation |
| Tubers (e.g., potatoes, cassava) | Promotes root development and nutrient storage |
| Cocoa/Coffee/Tea | Supports metabolic processes and bean/leaf quality |
| Flowers & Ornamentals | Enhances color vibrancy and overall plant vigor |
Applications in Food Industry:
Food Additive (E518)
- E number: E518.
- Approved by FAO/WHO, FDA, and EFSA as a safe food additive.
| Application | Purpose |
|---|---|
| Canned vegetables | Acts as a firming agent to maintain texture |
| Tofu production | Used as a coagulant (alternative to calcium chloride) |
| Salt substitutes | Added to low-sodium salt products |
| Baking | Used as a yeast nutrient in dough and flour enrichment |
| Chocolate and confectionery | Improves color and enhances texture |
| Beverages | Added to mineral water to increase magnesium content (fortification) |
Note on Use:
- Only food-grade magnesium sulphate (like Green OK if certified FCC/USP/BP) should be used for human consumption.
- Dosage must follow regulatory standards to avoid excessive intake (too much can cause diarrhea or GI upset).
Recommended Usage:
| Method | Rate & Instructions |
|---|---|
| Soil Application | 20–50 kg/ha depending on crop need |
| Foliar Spray | 5–10 g/L of water; apply early morning or late afternoon |
| Fertigation | 25–50 kg/ha through drip irrigation |
| Hydroponics | Use as a magnesium supplement in nutrient solutions |
Benefits:
- Corrects magnesium and sulfur deficiencies.
- Enhances crop yield and quality.
- Improves fertilizer efficiency when used with NPKs.
- Supports greener leaves, stronger stems, and better flowering.
