Application
1.Agricultural Grade Magnesium Sulphate Heptahydrate provides a soluble source of Magnesium and sulfur for plants.
Magnesium is also a secondary micronutrient, is essential for chlorophyll production and is therefore important in photosynthesis.
Magnesium is also important for protein synthesis and enzyme processes, and it helps plants to absorb and use phosphorus and nitrogen.
In addition, Sulfur is a component of amino acids and proteins. It is important for plant metabolic functions and enzyme processes.
2.Sulfur containing components help regulate ion transport across bio-membranes and are important in tolerance of plants of salt, drought and heat.
Sulfur-containing components also help to detoxify heavy metals in plants. A shortage of sulfur inhibits protein synthesis and decreases chlorophyll content in leaves.
There are numerous rural plants which require a considerable measure of magnesium like tomatoes and potatoes.
Our agricultural grade Magnesium Sulphate Heptahydrate can be applied directly to the soil, or dissolved in water and used as a foliar spray.
