Haifa Bitter-Mag Magnesium Sulfate Epsom Salt is a fully water-soluble fertilizer and a highly efficient source of Magnesium Sulfate for plants. It is a good fertilizer at preventing and curing of magnesium deficiency in plants, which if left unattended can lead to death or a very weak harvest.

Haifa Bitter-Mag fertilizer can be applied in combination with other fertilizers to meet crop nutritional needs throughout the growth cycle. Its high purity and water-solubility make Haifa Bitter-Mag an ideal fertilizer for Nutrigation and for foliar application.

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

Additionally, Haifa Bitter-Mag is suitable for preparation of fertilizer blends and production of liquid fertilizers.

TIP: Haifa BitterMag should not be mixed with calcium (calcium nitrate), sulphates (magnesium sulphate) or phosphate (mono potassium phosphate) fertilizers.
