Colored Magnesium Sulfate Granules
Product Information
Product Name: Colored Magnesium Sulfate Granules
Grade: Agricultural / Industrial / Customized Grade
Appearance: Uniform colored granules (commonly green, blue, red)
Purity (MgSO₄): ≥98%
Particle Size: Customizable (e.g., 1–3 mm, 2–4 mm)
Product Description
Colored Magnesium Sulfate Granules are high-purity magnesium
sulfate products enhanced with color for better visual
identification and differentiation. They are widely used in
agriculture and landscaping, especially in blended fertilizers
where color helps distinguish between components. These granules
retain excellent solubility, stable composition, and are easy to
handle due to their low-dust and uniform particle size.
Product Features
This product offers high purity and provides essential magnesium
and sulfur for plant nutrition. The granules are evenly colored and
flow smoothly, making them suitable for mechanical spreading. Both
color and particle size can be tailored according to customer
requirements.
Applications
In agriculture, these granules are used as a visible magnesium
fertilizer, especially in customized NPK blends. In horticulture
and landscaping, they serve as both a soil conditioner and an
aesthetic enhancer. They are also used in branded fertilizers where
color differentiation supports marketing and product traceability.
Packaging and Storage
Standard packaging includes 25kg woven or paper bags and jumbo
bags. Customized packaging and labeling are available upon request.
The product should be stored in a cool, dry place, away from
moisture and direct sunlight to maintain granule quality and
performance.
