Dolomitic Limestone (Calcium Carbonate) applications are used to increase and neutralize the pH in the soil. Reducing the acidity of the soil encourages healthy growing conditions for the grass. Important plant essential nutrients that are unavailable under acidic soil conditions become available to the plant as the soil is neutralized. Annual lime applications are recommended in regions that have acidic soil pH levels.
Dolomitic limestone is natural and is safe for humans and pets.
