Dolomite, also known as "dolostone" and "dolomite rock," is a sedimentary rock composed primarily of the mineral dolomite, CaMg (CO 3) 2. Dolomite is found in sedimentary basins worldwide. It is thought to form by the postdepositional alteration of lime mud and limestone by magnesium-rich groundwater. Dolomite and limestone are very similar rocks.


The further content of minerals in the fertilizers are added during the production process, prior to the final prilling or granluation. Physical properties. For the fertilizer to have the desired physical properties is important for the farmer in order to succeed in his spreading of the product in an even and controlled manner.
