Dolomite

Dolomite is Calcium and Magnesium carbonate and is used to increase the pH in acidic soils where extra magnesium is required. It can also help to break up clay soils due to its calcium content. Australian dolomite has a high calcium and magnesium content equal to around 95% carbonate with a neutralising value of around 100%. As with lime, it is quite slow acting and is supplied finely ground to increase the uptake. The advantage of this is that it can be applied with organic matter such as Humates without decreasing the benefits of the organic content.
