Magnesium is vital for plant growth and health as it serves to metabolize carbohydrates.  Its use is associated with a fast "green-up" of the plant because of its role in enabling photosynthesis, the resulting product of which is chlorophyll (the green).

How to Apply

Magnesium Sulfate is applied as a foliar when a magnesium deficiency is evident. Lighter-colored leaves and leaf outlines that are dry and brittle can be signs of a magnesium deficiency. To apply magnesium sulfate, the salt crystals will need to be dissolved. These crystals are highly soluble for ease of application.

General Foliar Application
• The rate of application should be determined based on the results from a tissue analysis, but, in general, rates are between 3 - 5lbs per acre, dissolved into 75 - 100L water. 

* A jar test should be conducted when mixing Magnesium Sulfate with any other product to ensure compatibility.
