Magnesium Sulfate

This agricultural-grade magnesium sulfate heptahydrate (MgSO4•7H2O) is an extremely soluble and bioavailable source of magnesium and sulfur for the health of animals and plants.


For plants:

Magriculture contains essential plant nutrients: magnesium and sulfur

Optimum solubility needed to make true clear solutions and compatible with other soluble nutrients except concentrated calcium and phosphorus solutions.


Ideal source for all Fertigation Systems: center pivot, micro-jet, drip-trickle, hydroponic and foliar spray applications. OMRI approved for use in organic growing as plant or soil amendment to overcome a documented soil deficiency for magnesium.

Magnesium is critical as a central element in the chlorophyll molecule to capture energy from the sun and convert it to plant sugars via photosynthesis.


Magnesium is especially required in sandy soils, soils with low CEC, for crops with high Mg demand and in situations of high applications of ammonium-N and/or potassium
