Dolomite is a type of limestone , which comes from ground rock containing calcium-magnesium carbonate (CaMg [CO3]2) and has a higher neutralizing value that calcite limestone. Dolomitic limestone not only lowers pH but also can supply magnesium in soils that are deficient.
Ground Magnesium Limestone (GML) (MGO 18 % ++) is used as a soil conditioner; it corrects acidity, supplies calcium and magnesium to plant roots, and increases bacterial activity in the soil. which is very suitable for the following uses :
| Typical Chemical Properties | ||
| Dolomite | GML | |
| CALCIUM CARBONATE (CaCO3) | 54% | 38% |
| MAGNESIUM OXIDE (MgO) | 22% | 18% |
| CALCIUM OXIDE (CaO) | 30% | 30% |
| ELEMENTAL CALCIUM | 22% | 22% |
| MAGNESIUM CARBONATE (MgCO3) | 44% | 44% |
| ELEMENTAL MAGNESIUM | 12% | 12% |
| APPEARANCE | White-Grayish Powder | White-Grayish Powder |
