Why, When and How to Apply Lime to Your Lawn
Lime is a soil amendment made from ground limestone rock, which naturally contains calcium carbonate and magnesium carbonate. When lime is added to soil, these compounds work to increase the soil's pH, making soil less acidic and more alkaline. Even though lime includes calcium and magnesium, which are essential nutrients for healthy plant
What Does Acid Rain Do to Limestone? eHow
As acid rain falls to the earth's surface, limestone rocks and limestone components in soil will react with the rain, neutralize the acid and dissolve. As the limestone dissolves, the rocks will wear away, becoming pitted with rounded edges. The dissolution process will change the appearance of the landscape as the rocks slowly wear away over time.
Soil Treatment After Removing Pine Trees eHow
The amount of lime you use depends on your existing soil pH and the type of plant that you want to plant in the pine's former area.

This is the most commonly used material on the North Coast. It consists of limestone crushed to a fine powder and is usually the cheapest material for correcting soil acidity. Good quality lime has 3740% calcium. Burnt lime (calcium oxide) Also known as quicklime, burnt lime is derived by heating limestone to drive off carbon dioxide.
Limestone - an overview ScienceDirect Topics
Materials commonly used for soils Ground limestone or chalk (also called carbonate of lime or calcium carbonate CaCO 3) is the commonest material used at present. These are obtained by quarrying the limestone or chalk rock and grinding it to a fine powder. The finer the particle size the quicker the reduction of acidity.
