Kieserite Raw Materials |Rongqing Chemical, also called magnesium sulfate monohydrate, is an ideal and commonly solution to combat magnesium deficiencies in fields, gardens and lawns. kieserite serves as an important source of magnesium and sulphur for fertilizers.
Kieserite Raw Materials Magnesium sulfate fertilizer is a high – efficiency soil amendment and plant nutrient fertilizer that integrates Magnesium (Mg) and Sulfur (S). It is mainly composed of Magnesium Sulfate Monohydrate (MgSO₄·H₂O), which not only serves as a nutrient supplement but also improves soil acidity and structure. This product is widely used in grain crops, economic crops, and horticulture, making it an ideal choice for green agriculture and high – yield planting.

Kieserite Raw Material |Rongqing Chemical, also called Magnesium Sulfate Monohydrate, is an ideal and commonly solution to combat magnesium deficiencies in fields, gardens and lawns. kieserite serves as an important source of magnesium and sulphur for fertilizers.When applied to the ground in different horticultural and broad acre crops, the magnesium fertilizer raw materials slowly dissolve in water which makes it perfect because of its low solubility in water.

1.Dual – element supplementation: Magnesium is a core component of chlorophyll, which promotes photosynthesis and enzyme activation. Sulfur participates in protein synthesis and enhances the stress resistance of plants.
2.Soil improvement: It can adjust the pH value of acidic soils (the pH value can be increased by 0.3 – 0.5 units after continuous application for three years per mu) and enhance the soil’s water – retention and fertilizer – retention capacity.
3.High – efficiency absorption: With good water solubility, it can be quickly absorbed by crops, and the fertilizer utilization rate is significantly higher than that of traditional fertilizers.
🔹Comprehensive nutrition, increased yield and improved quality
🔹Significant yield increase: Reasonable application of kieserite fertilizer can increase the yield of magnesium – loving crops such as citrus, potatoes, and tea by 10% – 30%, and also increase the sugar content, vitamin C content, and other nutrients in the fruits.
🔹Quality improvement: It can improve the appearance (fruit shape, color), taste, and commercial value of crops. For example, it can increase the sugar content of strawberries and the amino acid content of tea leaves.
🔹Soil health and ecological friendliness
Soil neutralization: It can neutralize acidic soils, relieve soil compaction, and reduce the dependence on chemical fertilizers in the long – term use, thus reducing environmental pollution.
No pH value disruption: It does not directly affect the soil structure but supports plant health, and is suitable for improving special soils such as saline – alkaline soils and lateritic soils.
🔹Kieserite Raw Materials Advanced production Process and stable quality from Kieserite raw materials suppliers
Green processes: It is produced by green processes such as the sulfuric acid method and the by – product method. The magnesium fertilizer raw materials are widely available in Yingkou, such as magnesite and industrial by – product sulfuric acid, and the production cost is controllable.
Quality assurance: The enterprise has passed the ISO quality system certification, and the heavy metal residues are far lower than the limit standards (lead ≤ 5ppm, arsenic ≤ 2ppm).
🔹Flexible application and multi – scenario adaptation
Basal application: It is suitable as the base fertilizer for grain crops (wheat, corn) and economic crops (tea, tobacco).
Slow release Fertilizer: It can meet the nutritional needs of vegetables, fruits, and other economic crops during the critical growth periods.
Water – fertilizer integration: The kieserite raw materials dissolves quickly and is suitable for drip irrigation and sprinkler irrigation systems, saving water and fertilizer.
