Organic Soil Solutions Limestone

Limestone adds necessary calcium and magnesium to the soil while reducing acidity. Maintaining proper pH levels in your soil increases the availability of nutrients to your lawn and garden, allowing plants to grow to their full potential. We apply dolomitic limestone or calcitic limestone based on the soil test.

Changing pH in Soil -

The ideal pH range for soil is from 6.0 to 6.5 because most plant nutrients are in their most available state. If a soil test indicates a pH below 6.5, the usual recommendation is for the application of ground limestone. In addition to having the ability to raise pH, limestone contains calcium. Some prefer dolomitic limestone

What happens when acid reacts with limestone? | Questions ...

Jun 14, 2008 · Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will
