Ag Magnesium

Ag Magnesium (Magnesium Sulphate Heptahydrate)is a specialty fertiliser in crystalline granule form. It is an excellent fertiliser with highly water solubility in supplying magnesium and sulphur to enhance the synthesis of chlorophyll and amino acids. Ag Magnesium is also free from chloride, contains negligible heavy metal content (≤15ppm) and practically ideal to use with other specialty fertilisers. If concentrated Ag Magnesium solutions were prepared, it should not be dissolved with fertilisers containing phosphate (eg. Ag MKP) or calcium (eg. Ag Calcium Nitrate).
