Magnesium Sulphate (Heptahydrate & Monohydrate) is available in granular and water soluble crystals suitable for agricultural applications. Magnesium Sulfate is epsom salt for plants (MgSO₄), providing a good source of both magnesium and sulphur. General analysis Mg 15% , S 17% Soluble - Magnesium sulphate heptahydrate is a fully water soluble magnesium and sulphur fertiliser.
Kieserite (MgSO4· H2O) is used in the agricultural industry as a source for both magnesium and sulphur. Most commonly used in horticulture, one of its great benefits is that it is suitable for all types of crops and for use in any type of soil, regardless of pH level. It is a fast-acting water soluble
Many of Australia's soils are sufficient in magnesium however high yielding horticultural crops often require additional magnesium to meet plant demands. Also high potassium inputs can often create a magnesium imbalance in plants. Where high levels of potassium are being applied it is also beneficial to apply magnesium. We use Magnesium Oxide in balanced fertililser
