Magnesium Sulphate Heptahydrate(MgSO4-7H2O)

Magnesium Sulphate Heptahydrate (MgSO4-7H2O)as the heptahydrate sulfate mineral epsomite of Magnesium Sulphate, is commonly called Epsom salt. In gardening and other agriculture, magnesium sulfate is used for correcting a magnesium or sulfur deficiency in soil; magnesium is an essential element in the chlorophyll molecule, and sulfur is another important micronutrient.

Product Details

 

Overview:

It is the most commonly applied to potted plants, or to magnesium-hungry crops, such as potatoes, roses, tomatoes, lemon trees, carrots, and peppers. The advantage of magnesium sulphate over other magnesium soil amendments (such as dolomitic lime)is its high solubility,which also allows the option of foliar feeding. 

 

Solutions of magnesium sulfate are also nearly neutral, as compared to alkaline salts of magnesium, as found in limestone; therefore, the use of magnesium sulfate as a magnesium source for soil does not significantly change the soil pH value.

Usage

Magnesium sulfate can be mixed with other fertilizers or organic fertilizers and applied in the soil before farmland. Generally, the amount of magnesium sulfate used for agricultural use is about 150kg per ha.

 

Magnesium sulfate topdressing should be applied early, and furrow application or flushing with water can be used. Generally, 150-200kg magnesium sulfate is suitable for each ha. of land, and 250-500g magnesium sulfate can be applied to each fruit tree; after sufficient magnesium fertilizer is applied, it can be applied again after several crops, and it is not necessary to apply magnesium sulfate every season.

 

Generally, the foliar spraying concentration of magnesium sulfate is 0.5% - 1.0% for fruit trees, 0.2% - 0.5% for vegetables, 0.3% - 0.8% for rice, cotton and corn, and the application amount of magnesium fertilizer solution is about 800-1200 kg per ha.

 

Storage:
