Crushed limestone is used to alleviate soil acidity levels for plant and crop growth. Generally, crushed limestone is used in gardens where soil is highly acidic. Ag lime is a form of soil conditioner that decreases and maintains the right amount of soil acidity for gardening and landscaping. Ag lime has calcium carbonate that is an essential ...

Limestone Corrects the Soil pH. Chances are that the soil in your field or garden will become acidic over time due to several factors, including decomposition of organic material and erosion. Limestone raises the pH level to a neutral range beneficial to plants, typically between 5.5 and 6.5.

limestone, sedimentary rock composed mainly of calcium carbonate (CaCO 3 ), usually in the form of calcite or aragonite. It may contain considerable amounts of magnesium carbonate (dolomite) as well; minor constituents also commonly present include clay, iron carbonate, feldspar, pyrite, and quartz. Most limestones have a granular texture.

For example, a farmer submits a soil sample and the analysis indicates the 3 tonnes per acre of pure calcium carbonate are required to neutralise the pond soil acidity (or to produce alfalfa). The agricultural limestone available at the local farm supply store has an NV of 85 percent and an NE of 71 percent.

Show timer Statistics. Earthworms, vital to the health of soil, prefer soil that is approximately neutral on the acid-to-alkaline scale. Since decomposition of dead plants makes the top layer of soil highly acidic, application of crushed limestone, which is highly alkaline, to the soil's surface should make the soil more attractive to earthworms.

Soils are acid because of hydrogen ions dissolved in soil solution (water in the soil) and held on the clay and humus particles. pH is a measure of the degree of acidity or alkalinity. A value below 7.0 is acid, 7.0 is neutral and above 7.0 is alkaline. As the soil pH decreases below 7.0, soils become more and more acidic.
