CAS 10034-99-8
Magnesium Sulphate
Magnesium Sulphate supplies magnesium and sulphur to crops and livestock, as fully soluble heptahydrate for fertigation and monohydrate for soil application.
Magnesium is the central atom of chlorophyll, so deficiency shows as yellowing between leaf veins and reduces yield, particularly in fruit, vegetables, plantation crops and on sandy or acidic soils. Magnesium sulphate corrects it while also supplying sulphur.
Heptahydrate (Epsom salt, about 9.6% Mg) dissolves completely and is used in fertigation, hydroponics and foliar sprays. Monohydrate (about 16% Mg) is more concentrated and is used for soil application and blending. Feed grades supply magnesium in animal diets.

Magnesium Sulphate — frequently asked
Magnesium sulphate heptahydrate dissolves fully and quickly, making it the choice for fertigation, hydroponics and foliar sprays. Monohydrate contains more magnesium per kilogram and suits soil application and fertiliser blending.
Magnesium deficiency typically shows as yellowing between the veins of older leaves while the veins stay green, followed by reduced growth and yield.
