Magnesium Sulfate Heptahydrate is the hydrated form of magnesium sulfate with the chemical formula MgSO₄·7H₂O. It is commonly known as Epsom Salt.
Yes. It is highly soluble in water and is therefore suitable for preparing aqueous solutions and, where agronomically appropriate, for fertigation systems.
Yes, suitable agricultural grades can be used in drip irrigation and fertigation programs where magnesium and sulfur supplementation is required.
Yes. Its high water solubility makes appropriate grades suitable for sprinkler-based fertilizer application, subject to the irrigation system and agronomic recommendations.
It can be used as a magnesium and sulfur source for various fruit crops when soil or plant nutrition indicates a requirement.
Correcting a magnesium deficiency may improve crop performance, but fruit sweetness depends on many factors. Magnesium sulfate should therefore be considered part of a balanced crop nutrition program rather than a guaranteed sweetness-enhancing product.
The international 6-digit HS subheading is 283321 – Sulphates of magnesium. India commonly uses 28332100 as the tariff item.
Magnesium Sulfate Heptahydrate (Epsom Salt) is a versatile, highly water-soluble source of magnesium and sulfur with applications across agriculture, horticulture, fertigation, animal nutrition, aquaculture and industry.
Its excellent solubility makes it particularly valuable for drip irrigation, sprinkler irrigation and other water-based agricultural applications, while its chemical properties support a range of industrial uses including selected wastewater-treatment, mineral-processing, leather and paper applications.
For reliable commercial supply, customers should select the grade according to the intended application and request the corresponding COA, TDS and SDS before purchase.
Magnesium Sulfate Heptahydrate | Epsom Salt | MgSO₄·7H₂O | CAS 10034-99-8 | HS Code 283321
One of the major advantages of Magnesium Sulfate Heptahydrate is its excellent water solubility.
This makes it particularly suitable for applications where magnesium and sulfur need to be delivered through irrigation water or prepared as an aqueous solution.
It can be used in:
Drip irrigation
Sprinkler irrigation
Fertigation
Greenhouse cultivation
Horticulture
Fruit production
Vegetable crops
Field crops
Specialty agriculture
The suitability of a particular grade should be confirmed against the crop, irrigation-water quality and local agricultural requirements.
Magnesium is an essential plant nutrient and plays an important role in plant growth, including its role in chlorophyll and photosynthetic processes.
Because Magnesium Sulfate Heptahydrate dissolves readily in water, it can be incorporated into suitable fertigation and irrigation programs.
It is particularly useful where soil or crop conditions indicate a requirement for supplemental magnesium and sulfur.
Drip irrigation systems
Sprinkler irrigation systems
Fertigation systems
Greenhouse irrigation
Orchard irrigation
Commercial horticulture
Fruit plantations
Vegetable production
For South American agricultural markets, product selection, dosage and application should be adjusted according to local crop conditions, soil analysis and agronomic recommendations.
