1 Magnesium Sulphate is a sulphate based magnesium and sulphur fertilizer. It contains the nutrients magnesium and sulphur in a fully water-soluble and therefore immediately plant available form. It also has many medical uses, and used bath additive known as epsom salts. CAS RN.: ( andyrous ); (Heptahydrate) EINECS: H.S.CODE: The advantages of ChoiceChem MgSO4 Fully water-soluble Consists of 100% plant nutrients 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. 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.

Application Fertilizer Used to correct a magnesium or sulfur deficiency in soil Medicine It has laxative properties and provides relief from constipation. Used for the treatment of preeclampsia in pregnant women. It is administered intravenously or intramuscularly to pregnant women in order to prevent premature labor. It is also used to reduce convulsions during childbirth. Used for treating severe asthma attacks. Epsom salt dissolved in water can be applied topically on arthritic joints; patients suffering from osteoporosis have also experienced marked improvement in the painful condition after application of Epsom salt gel. Epsom salt is used in flotation therapy can complete relaxation of the body. It can cure a number of skin problems. Epsom salt can be included in the hair care regime as well. Additive Magnesium sulfate heptahydrate or Epsom salt needs to be added in marine aquarium after frequent interval of time. This is done to prevent deficiency of magnesium in the saltwater. Dehydrating agent Anhydrous magnesium sulfate acts as an excellent dehydrating agent in chemical synthesis of organic compounds. coagulating agent Used as a coagulating agent in soy milk for making tofu. 4.

Packing In 25kg / 1000kg / 1100kg / 1200kg / 1250kg pp bags Packing with pallets; 25MT/20 FCL. 7. Application Recommendations As base fertilizer, magnesium sulphate can be used as a straight fertilizer or as a component in compound fertilizers. As dressing fertilizer, magnesium sulfate can be used in ditches or dissolved in water, once gives full measure. As foliar fertilizer, magnesium sulfate can be used in the initial growing period and middle growing period. There are different requirements of spraying concentration in different crops and the different growth stages of the same crop. For instance, fruit trees should be %; vegetables should be % and crops should be %. - Fertilizer recommendations for various crops based on yield Crop Yield (Mt/ha) Magnesium Sulphate (Kg/ha) Banana Cocoa Coffee (cherries) Grape Maize Oil palm (FFB) Orange
