Kieserite Granular, Magnesium Sulfate Heptahydrate, and Customized Trace-element Blended Fertilizers. These products feature high-purity magnesium oxide (MgO≥20%-30%), Ideal hardness and water-soluble, Suitable for machine broadcasting and kinds of application scenarios, offering advantages such as soil improvement and enhancement chlorophyll synthesis in crops, and stress resistance. They are particularly suitable for tropical cash crops as oil palm, durian, banana, and rice.
At the exhibition, Rongqing Chemical’s technical leader explained: “Tropical climates with heavy rainfall and soil acidification cause severe magnesium loss, yet magnesium is crucial for plant photosynthesis and enzyme activity. Our kieserite not only replenishes essential secondary nutrients, but also restores soil ecosystems through optimized ratios of calcium, zinc, boron, and other trace elements, significantly boosting crop yield and quality.”
Leveraging the local resource advantages of Dashiqiao, Yingkou, Liaoning—known as “China’s Magnesium Capital”, Rongqing Chemical utilizes high-grade magnesite ore raw material. Combined with proprietary grinding and granulation processes, Rongqing Chemical produces Kieserite/Magnesium Sulfate in powder or granular forms, offering OEM/ODM customization services. Tailored to diverse crop requirements, Rongqing Chemical flexibly incorporates potassium, calcium, silicon, boron, selenium, and other elements into this kieserite. For examples, Rongqing Chemical DR designed a high-magnesium formulation for Malaysian oil palm plantations and a high-zinc blend granular fertilizer for rice cultivation, effectively addressing local soil magnesium imbalances caused by excessive NPK fertilizer use.
During the exhibition, Rongqing Chemical’s booth attracted distributors and farmers from Southeast Asian countries including Thailand, Vietnam, Indonesia, and Malaysia, with multiple companies reaching cooperation agreements on-site. “Rongqing’s magnesium sulfate demonstrates outstanding performance in Malaysian oil palm cultivation, effectively alleviating leaf yellowing issues,” remarked a Southeast Asian Fertilizer buyer. “Their customized services align perfectly with our practical needs.”
