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
