DOLOMITE
Correct Magnesium deficiencies and neutralise soil acidity with the application of high quality Dolomite that is 100% natural and Australian mined and refined calcium magnesium carbonate.
Dolomite is a is great source of calcium and magnesium for plants. It is naturally occurring rock containing calcium carbonate and magnesium carbonate (CaCO3.MgCO3). Where both magnesium and lime are required, dolomite is often more cost-effective than applying magnesium and lime separately.
Dolomite can provide a quick acting acid soil neutraliser. Even when the liming value is not considered, dolomite is often used as a source of magnesium, as the availability of the magnesium is increased, relative to Magnesium Oxide, due to its finely ground nature. There is also the added benefit of silica in the dolomite.
Pacific Fertiliser supply dolomite in Fine, Super Fine, Ultra Fine and Granular grades in bulk, bulkbags or pallets of 25kg bags.

Dolomite is typically applied at rates of about 100-300kg/ha. However, rates of up to 1000kg/ha may be warranted, depending on the amount of Magnesium required. Granular dolomite can also known as OzCalMaged and MagPrilled.
Dolomite is often mixed with lime, RPR, Sulphur, and Potash, which PacFert can blend and deliver to meet your soil requirements.
We can also supply Kieserite or magnesium sulfate mineral (MgSO. 4· H2O), to assist in adjustment of Mg.Ca ratios.
MAGNESIUM BLENDS:
In some locations and for some applications, magnesium blends maybe more cost effective. Pacific Fertiliser can blend in a quality magnesium carbonate, magnesium oxide or magnesium sulphate product (powder or granule) into Ag lime or in other blends to give you the exact Magnesium % to meet your requirements.
