What is Cal-Mag?
Cal-Mag is a carbonate mineral primarily compromised of Calcium and Magnesium.
Our Cal-Mag is the perfect fertiliser for raising the pH level of soils and provided a boost of magnesium. If your soil has a low pH, and you're growing crops that require high levels of magnesium to grow significant yields, then our Cal-Mag is right for you.

The benefits of using Cal-Mag
Supplies both Calcium and Magnesium to the soil while also having a neutralising value.
Can be mixed according to the percentage of Magnesium that your crop requires - We mix the CalMag using Marule Ag-Lime and Magnesium supplied by QMAG.
Corrects Calcium and Magnesium deficiencies and any acidifying issues associated with most soil fertilisers
Spreading Services Available
We're also available to spread Ag-Lime onto your soil, making your Ag-Lime purchase even easier. Check out our spreading service page for more details.
