AREAS OF USE

Formulation of Plant Nutrition Products
Magnesium Sulphate Anhydrate serves as a magnesium source in the formulation of plant nutrition products. Its low moisture content offers an advantage in terms of faster homogenisation of powder mixtures. For liquid formulations, the heptahydrate form is more commonly used due to its superior solubility in water. Please contact our company for detailed information and technical support regarding the use of Magnesium Sulphate Anhydrate in plant nutrition product formulations.

Agriculture
Magnesium Sulphate Anhydrate is not only used as a raw material in plant nutrition product formulations but also as a direct fertiliser in agriculture. It is essential for increasing the magnesium or sulphur content in soil. It is commonly applied to potted plants or magnesium-deficient crops, including potatoes, tomatoes, carrots, peppers, lemons, and roses. Due to its high solubility, foliar feeding is also an effective option. The use of Magnesium Sulphate Anhydrate to supply magnesium does not significantly affect soil pH.

Feed Additive
Magnesium is a macro-mineral necessary for the healthy growth and development of animals. Magnesium Sulphate Anhydrate is used as a feed additive to correct magnesium deficiencies. A deficiency in magnesium can lead to meadow tetany disease. It also helps regulate the nervous system and prevents muscle contractions. Magnesium Sulphate Anhydrate is used in pet food formulations as well.

Industrial Applications
Anhydrous Magnesium Sulphate is required in the production of refractory materials. In the textile industry, it is used as a dye fixative to enhance the processing and refining of fabrics such as cotton and linen. Additionally, anhydrous Magnesium Sulphate is used as a mild desiccant for organic solvents in chemical laboratories. A solution of Magnesium Sulphate and Magnesium Chloride is employed in liquid soaps, detergents, and rinsing agents to regulate viscosity.


Why Use Magnesium Sulphate in Plants?
Plants require a variety of macro and micronutrients for healthy growth and development. Magnesium is one of the essential elements. Magnesium is a key component of chlorophyll in plant cells, which is crucial for photosynthesis. Without sufficient magnesium, chlorophyll cannot form, resulting in plants not turning green, stunted growth, and lack of fruit production. Magnesium Sulphate is an efficient fertiliser that meets plants’ magnesium needs. It also improves plant performance under stress and helps remove toxic elements. Adequate magnesium is necessary for healthy plant growth and development, making the use of Magnesium Sulphate essential for fertilisation.


What is Magnesium Sulphate Anhydrate?
Magnesium and sulphate naturally occur in organic forms. In order to make these two elements more effective for use in various applications, an inorganic substance with anhydrous properties is used. Magnesium Sulphate Anhydrate (MgSO₄) is a water-soluble compound with a chemical formula of MgSO₄, a molar mass of 120.37 g/mol, and a crystalline, white appearance. It is commonly used as a fertiliser but also finds applications in beauty products, the pharmaceutical industry, yeast dough production, and detergent manufacturing.


Magnesium Sulphate in Plant Growth
Magnesium is essential for plants, as it plays a crucial role in photosynthesis by being a central component of chlorophyll. A magnesium deficiency causes chlorophyll production to stop, leading to yellowing, stunted growth, and eventually, a lack of fruit. Magnesium Sulphate is a fertiliser that supplies magnesium directly to plants, helping them recover and improve their quality and yield. It also promotes healthy growth by assisting in the absorption of other nutrients and improving water usage efficiency.


Application of Magnesium Sulphate in Agriculture
Magnesium Sulphate Anhydrate helps regulate water requirements in plants, supports phosphorus uptake, enhances leaf resistance, and improves overall disease resistance. It also contributes to maintaining soil pH balance, enhancing soil fertility, and aiding in the absorption of excess water.

Magnesium Sulphate Anhydrate as a Fertiliser
When used as a fertiliser, Magnesium Sulphate Anhydrate offers numerous benefits:

  • Maintains pH levels in plant leaves

  • Ensures anion and cation balance in plants

  • Enhances photosynthesis by facilitating the use of sunlight

  • Contributes to overall plant development

  • Promotes faster and more abundant crop production

  • Increases leaf resistance to pests and diseases

  • Improves soil fertility

  • Enhances moisture retention in the soil

These benefits make Magnesium Sulphate a preferred fertiliser in professional agriculture, especially in open fields and greenhouses, where rapid growth and high yield are key goals.


Chemical and Physical Properties
Magnesium Sulphate Anhydrate (MgSO₄) is a mineral compound with 99% purity. It consists of magnesium oxide (32%), sodium oxide (65.7%), and magnesium (18.9%) molecular components. The solution’s pH typically ranges from 7 to 9. It is a white, colourless, and odourless substance that does not cause irritation upon skin contact. For optimal storage, it should be kept in a cool, moisture-free environment in a sealed package.


Why Should Magnesium Sulphate Be Used?
Magnesium Sulphate Anhydrate is vital for balancing magnesium and sulphur deficiencies in the soil. It serves as an effective nutrient source for plants, improving growth, colour, and vitality, especially for potted plants. It is particularly useful for crops like potatoes, tomatoes, peppers, and roses, which have high magnesium requirements.


How to Use Magnesium Sulphate Anhydrate?
The application of Magnesium Sulphate Anhydrate varies according to the plant species and irrigation methods. Common guidelines include:

  • For general plants: 300–500 grams per plant during the irrigation phase, from fruit setting to colour change.

  • For citrus fruits: Apply 600 grams per 100 litres of water, in 2–3 applications every 15–25 days.

  • For vegetables: Apply 300 grams per plant after planting, with 2–3 applications during the growing season.


Pricing
Magnesium Sulphate Anhydrate is available in various packaging and prices, depending on its application, quantity, and intended use.


Health Benefits of Magnesium Sulphate
Magnesium Sulphate has a variety of health benefits, including:

  • Treatment of pre-eclampsia and eclampsia in pregnancy through intravenous administration

  • Alleviating constipation through oral consumption

  • Wound care for cleaning and promoting faster healing

  • Asthma treatment by dilating the airways

  • Correcting magnesium deficiency (hypomagnesaemia) by replenishing magnesium levels

Always consult with a healthcare professional before using Magnesium Sulphate for medical purposes.
