Calcium Northeast Organic Farming Association

Agricultural limestone is the most common method for adjusting the soil pH. Two kinds of limestone are available, one being primarily calcium carbonate, or calcitic limestone, and the other a mixture of calcium and magnesium carbonate, often called dolomitic or simply high magnesium limestone. Both have approximately the same liming capability.
