Other forms of lime have common applications in agriculture and gardening, including dolomitic lime and hydrated lime. Dolomitic lime may be used as a soil input to provide similar effects as agricultural lime, while supplying magnesium in addition to calcium. In livestock farming, hydrated lime can be used as a disinfectant measure, producing ...
Southern Limestone-Dolomite Valleys & Low Rolling Hills ecoregion (67f, medium-dark orange) coursing through the states of Virginia, Tennessee, Georgia and Alabama.. The Southern Limestone/Dolomite Valleys & Low Rolling Hills (Ecoregion 67f) is one of the 99 Level IV ecoregions in the continental United States, as defined by a collaboration between the EPA, USGS and USDA.

Dolomite (also known as dolomite rock, dolostone or dolomitic rock) is a sedimentary carbonate rock that contains a high percentage of the mineral dolomite, CaMg(CO 3) 2. It occurs widely, often in association with limestone and evaporites , though it is less abundant than limestone and rare in Cenozoic rock beds (beds less than about 66 ...
Large quantities of processed dolomite are used in the production of float glass. In horticulture, dolomite and dolomitic limestone are added to soils and soilless potting mixes as a pH buffer and as a magnesium source. Pastures can be limed with dolomitic lime to raise their pH and where there is a magnesium deficiency.
Nutritive amendments should also be considered. Calcium and magnesium will be lacking in coir potting mixes, so a naturally good source of these nutrients is dolomitic lime which contains both. pH is of utmost importance as coir pith tends to have a high pH after some months of use, resulting in plant stunting and multiple deficiencies.
Lime is also used in making chemicals such as soda ash, caustic soda, bleaching powders, and water softening salt. Limestone was used to fill the caissons that support the Mackinac Bridge. [7] Pulverized limestone is used to restore the lime that is needed to make plants grow. Continuous cultivation depletes lime out of the soil, making it acidic.
In the lime industry, limestone is a general term for rocks that contain 80% or more of calcium or magnesium carbonate, including marble, chalk, oolite, and marl.Further classification is done by composition as high calcium, argillaceous (clayey), silicious, conglomerate, magnesian, dolomite, and other limestones. [5]
[4] [3] The remaining carbonate rock is mostly dolomite, a closely related rock, which contains a high percentage of the mineral dolomite, CaMg(CO 3) 2. Magnesian limestone is an obsolete and poorly-defined term used variously for dolomite, for limestone containing significant dolomite ( dolomitic limestone ), or for any other limestone ...
