Exceptional purity and safety

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:

• Contains essential plant nutrients: magnesium and sulfur
• Optimum solubility needed to make true clear solutions and compatible with other soluble nutrients
• Ideal source for all Fertigation Systems: center pivot, micro-jet, drip-trickle and foliar spray applications
• 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

For animals:

• Contains macro-nutrient magnesium and secondary nutrient sulfur
• Excellent solubility means greater animal bioavailability than other magnesium sources
• Effective magnesium for the prevention and treatment of hypermagnesemia and grass tetany, especially in early lactating dairy cows
• Effective magnesium nutrition in non-ruminant feeds; also used for enhanced mobility, reduced discomfort and a beneficial calming effect
• Magnesium is an important cofactor in enzymatic reactions vital to every metabolic pathway in every animal species
