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.
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.
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.
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.
