Description

Dipotassium Magnesium Disulphate Hexahydrate is a high-purity inorganic salt complex, also known as potassium magnesium sulfate. This compound serves as a critical source of essential plant nutrients—potassium, magnesium, and sulfur—in a highly soluble and bioavailable form. It is primarily utilized in the formulation of premium agricultural fertilizers and specialty nutrient solutions for hydroponic systems and high-value crops requiring precise mineral supplementation.

Application

• High-Efficiency Fertilizers: A key component in water-soluble and foliar fertilizer blends for correcting potassium, magnesium, and sulfur deficiencies in crops.
• Hydroponics & Soilless Cultivation: Provides a clear, soluble nutrient source for recirculating irrigation systems in greenhouse and controlled environment agriculture.
• Specialty Horticulture: Used in nutrient programs for sensitive high-value crops like fruits, vegetables, and ornamentals to improve yield and quality.
• Laboratory Reagent: Serves as a analytical standard or reagent in chemical analysis and research applications.
• Industrial Processes: Potential use in chemical synthesis and as a catalyst or additive in specific manufacturing processes.
