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.
