The Origin of Limestone

With the increase in atmospheric CO 2 in recent decades, especially downwind from coal-burning power plants, CO 2 dissolves in rain, forming "acid rain." Acid rain can harm vegetation and a region's ecology if not neutralized, for example, by coming into contact with limestone.

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
