Magnesium Sulfate ( MgSO4 ) is another staple of any good fertilizer nutrient formula. With 9.5% magnesium and 12.5% sulfate. One gram in one gallon of water yeilds 25 ppm magnesium and 33 ppm sulfur.
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
