Mineral raw materials for the fertilizer industry
Talk to our Industry expertsMAGNESIA has been your reliable partner for mineral compounds in fertilizer production for over 40 years.
Agriculture faces the challenge of sustainably increasing yields while maintaining soil fertility. Mineral raw materials play a central role in this: they supply essential nutrients, regulate the pH value and improve soil structure.
We offer proven quality, technical know-how and a broad portfolio of raw materials that are indispensable for the production of single- and multi-nutrient fertilizers as well as special formulations. With our products we support you in optimizing the nutrient supply of plants and increasing the efficiency of your fertilizers.

Applications of mineral materials as fertilizers in agriculture
Mineral raw materials are essential for the production of modern fertilizers. Our mineral products are available in various qualities – tailored to your requirements for purity, solubility and reactivity. This allows individual solutions for agriculture and the horticultural industry to be realized.
- Magnesium & calcium supply for healthy plant development
- pH regulation to improve soil structure & nutrient uptake
- Increasing nutrient efficiency through targeted mineral enrichment
- Special formulations for different crops & soils
- Technological processing aids for uniform granulation & storage stability
- Sustainable solutions for reducing environmental impact
Mineral raw materials for high-performance agriculture
Through the targeted use of mineral compounds, modern fertilizers can be developed that are optimally tailored to the needs of today’s agriculture. Proven components such as oxides, carbonates and sulfates ensure the supply of important nutrients and regulate the pH value. Furthermore, the MagSpheres® series provide additional improvements by, for example, increasing flowability, reducing the weight of granulates or storing moisture for longer periods and releasing it to the soil.

Why mineral raw materials are indispensable in the fertilizer industry
Mineral raw materials are the foundation for efficient and sustainable plant production. They supply essential nutrients such as magnesium, calcium and sulfur, which are decisive for growth, photosynthesis and the fertility of the soil.
Magnesium oxide and magnesium sulfate are, for example, indispensable sources of magnesium, which plays a key role in chlorophyll formation. Calcium carbonate neutralizes acidic soils and improves soil structure, while calcium nitrate enables rapid nitrogen supply.
