Dolomite is a limestone processed with 18% to 23% calcium and 8% to 12% magnesium. It may also contain 2% or less sodium. It is an anhydrous carbonate mineral with the formula of CaMg(CO₃)₂. This is a rock-forming mineral that is rarely found in modern sedimentary environment.
Physical Features of Dolomite
It comes with three directions of great cleavage that can be observed with a hand lens when it is coarsely crystalline. It comes with the Mohs hardness of 3 1/2 to 4. It gives very weak reaction to dilute and cold HCL.
Benefits of Dolomite in Agriculture
This mineral is considered as one of the options for changing the acidity or pH level of the soil. It is best to use when the pH of soil is 5.9 or below. It ensures to enhance the pH value for making the soil more effective, healthy and plant-friendly. This is used to be added to the soil having vegetables with many seeds like tomatoes as they require more amount of calcium for their growth.
Other Advantages of Dolomite
Dolomite stone is used in the construction industry to develop road base material, concrete and asphalt, cement, etc. This is also used for acid neutralization and glass production. It can also be added as a feed additive for livestock. It serves as oil reservoir rock, lead and zinc deposits.
When to Use Dolomite In Soil?
This can be added to yard, garden, flower beds and vegetable soil any time when there is no freezing temperature. To get the utmost benefit of this mineral, it is best to add in spring or fall season. It is sure to enhance the quality and nutritional values of soil to boost the growth of plants.
How to Use Dolomite?
If dolomite is to be added to an empty garden, then turn it into the 6 inches of the soil. Check the pH level of soil before adding it to ensure to use accurate quantities. For instance, if there is a need to enhance the pH to 6.5, then 10 pounds per 100 square feet should be added.
