99.5% Magnesium Sulfate Hepta Hydrate Powder Personalized Customization

• Detailed introduction of Magnesium sulfate heptahydrate fertilizer

Magnesium sulfate heptahydrate, commonly known as "Epsom salt" or "sulfur bitter", is a dual-nutrient fertilizer containing magnesium and sulfur. Its chemical formula is MgSO₄·7H₂O, indicating that each magnesium sulfate molecule is combined with seven water molecules. In agriculture and horticulture, it is one of the most commonly used and effective fertilizers for supplementing magnesium and sulfur.

• Basic Characteristics

• Appearance: Usually colorless or white crystals, granules or powder, readily soluble in water.

• Nutritional components:

• Magnesium (MgO) : With a content of approximately 16%, it is the core atom of chlorophyll and is crucial for photosynthesis.

• Sulfur(S) : With a content of approximately 13%, it is an essential element for the synthesis of proteins, vitamins and enzymes.

• Solubility: It is highly soluble in water, neutral in nature, and belongs to fast-acting fertilizers, which can be quickly absorbed by plant roots and leaves.

• pH value: The aqueous solution is neutral and suitable for all types of soil, without altering the soil's pH level.

• Core role and function

• Supplement magnesium:

·It constitutes the central atom of chlorophyll and directly participates in photosynthesis, promoting the synthesis of carbohydrates. 

· Prevention and correction of magnesium deficiency: The typical symptom is interveinal chlorosis and yellowing of old leaves (the veins remain green), and in severe cases, the leaves turn yellow or white, affecting yield and quality. 

·Promote enzyme activation and participate in the synthesis of fats, proteins and vitamins.

• Supplement sulfur elements:

• Effects on soil

· Improve the balance of cations such as calcium, magnesium and potassium in the soil. Sulfur can promote the activation and absorption of other nutrients in the soil.

• Mainly applicable to crops

· Cash crops: tobacco, cotton, sugarcane, tea, rapeseed. 

· Fruit trees: citrus fruits, grapes, bananas, lychees, longans, apples (can effectively prevent "apple bitter pit disease"). · Vegetables: Tomatoes, potatoes, peppers, cucumbers, beans. 

· Field crops: corn, rice, wheat. 

· Flowers and ornamental plants: roses, hydrangeas, hybrid roses, etc. (Often used to correct yellow leaves and promote flowering).

• Advantages and precautions

• Advantages:

· Quick-acting and highly effective: Excellent water solubility and rapid absorption. 

· Dual nutrition: Simultaneously supplement two medium elements. 

· Safe and gentle: Neutral, less likely to burn leaves and roots, and has good compatibility. 

· Low cost: High cost performance.

• Precautions

· Treat the symptoms: Use it only after confirming that it is a symptom of magnesium or sulfur deficiency to avoid blind application. 

· Avoid overapplication: Excessive application may lead to an imbalance of ions in the soil or cause deficiencies of other nutrients such as potassium and calcium. 

· Do not mix with alkaline substances: Do not mix with strong alkaline substances such as lime and wood ash to avoid the formation of insoluble precipitates and reduce fertilizer efficiency. 

·Storage: Keep sealed and store in a cool and dry place to prevent caking.

• Summary

Magnesium sulfate heptahydrate is a specific, efficient and economical magnesium-sulfur supplementary fertilizer. Correctly identifying the nutrient deficiency signals of crops and using it scientifically and reasonably can effectively solve the problem of yellow leaves, significantly enhance photosynthesis, increase crop yield, quality and stress resistance, and is an indispensable "nutritional supplement" in modern precision agricultural management.
