The advantages of MgSO4
l Fully water-soluble
l Consists of 100% plant nutrients
l 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.
l 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.

2.Function of magnesium sulphate:
Magnesium is the center element of chlorophyll,photosynthes can't go on without it. It is the activating agent of many enzymes,such as it can promote the metabolism of carohydrates,nucleic acid synthesis,the conversion of phosphate,etc.
It involves in the synthesis of proteins as an element of multi-core proteins,it's the transmission medium of genes as part of the composition of genes
3.Magnesium sulphate for agriculture
The symptoms of lacking of "sulfur"and"magnesium":
1 )it lead to exhaustion and death if it's serious lacked;
2 ) The leaves became smaller and its edge will became dry shrinkage.
3 ) Susceptible to bacterial infections in premature defoliation.
4. Deficiency symptoms
The deficiency symptom of interveinal chlorosis first appears in olderleaves. Leaf tissue between the veins may beyellowish, bronze, or reddish, while the leafveins remain green. Corn leaves appear yellow-striped with green veins, show orange-yellow color with green veins.
5. Storage & Handing
l Store in the tightly closed container.
l Store in a cool, dry, well-ventilated area away from incompatible substances.
l Recommended storage conditions 68 - 100ºF and 54 – 87% relative humidity.
