Pure fertilizer with (16% Magnesium (MgO) + 32% Sulphate (SO3)) produced by Ekmekçioğlu company in Turkey is used to increase the amount of magnesium or sulfur in the soil. Magnesium sulfate is an inorganic salt containing magnesium, sulfur and oxygen. It is most commonly applied to magnesium hungry plants such as potatoes, tomatoes, carrots, peppers, lemons and roses. The advantage of magnesium sulfate over others is its high solubility, which allows it to be a foliar feeding option. Magnesium sulfate solutions are nearly pH neutral compared to alkaline magnesium salts with limestone; Therefore, the use of magnesium sulfate as a magnesium source for soil does not significantly alter soil pH.
