The advantages of MgSO4

(1)Fully water-soluble

(2)Consists of 100% plant nutrients

(3)Efficient Mg and S nutrients for the light soil and acid soils, especially for the calcareous soils and soils with a high pH, which high calcium concentrations in the soil solution impede the magnesium availability.

(4)Granular fertilizer has excellent spreading properties due to the well-defined granulometry and the hardness of the granules. These qualities also make it equally well suited for bulk blending.
