Colored Magnesium Sulfate Heptahydrate Granules (MgSO₄·7H₂O), dyed in a vibrant yellow hue, are specially designed for industries that require clear visual differentiation in blending, application, or packaging processes. This product maintains all the chemical integrity and functional performance of high-purity magnesium sulfate heptahydrate while incorporating safe, non-toxic coloring agents compliant with relevant safety and environmental regulations.
Manufactured in compliance with USP, BP, EP, and CP quality standards, these yellow-dyed granules offer both visual appeal and precise nutrient delivery. The base compound, MgSO₄·7H₂O, contains two essential secondary nutrients—magnesium and sulfur—vital for plant metabolic processes, including chlorophyll production, enzyme activation, and amino acid synthesis. The product also features high water solubility, rapid dissolution, and consistent particle size distribution, which makes it suitable for both direct application and formulation into compound fertilizers.
The yellow coloring serves practical purposes in quality control and traceability, helping operators visually identify the product during storage, transport, and usage. It is particularly useful in mixed formulations, where it helps confirm even distribution and prevents cross-contamination errors. The coloring agents used are water-soluble, non-reactive, and designed to fully degrade in agricultural and environmental conditions, leaving no residue.
These dyed granules are commonly applied in precision agriculture, hydroponic nutrient systems, landscaping, turf management, and industrial processes requiring colored indicators. Their bright appearance enhances product recognition while ensuring the same high-performance nutrient profile as standard white magnesium sulfate granules.
The product is available in multiple particle sizes and can be customized upon request to meet the needs of automatic fertilizer spreaders, controlled-release systems, or specific industrial processing environments. Each batch undergoes rigorous quality control to ensure conformity in color intensity, granule size, and nutrient content.
The product is free-flowing, dust-minimized, and compatible with most nitrogen, phosphorus, and potassium fertilizers. It is non-hygroscopic under normal storage conditions and has a shelf life of up to 24 months when stored properly in cool, dry conditions away from direct sunlight.
