Limestone, pH and calcium - Progressive Forage

One of the most common points of confusion concerns limestone, pH and calcium. Many think these refer to the same thing. There is a big difference in pH and calcium, as well as limestone and limestone sources. Knowing the difference can mean big yield and quality increases in your forages. Limestone is mainly used in agriculture to regulate soil acidity, but highly reactive calcitic lime can ...

Dolomite was named after the Dolomite mountains in southern Europe. It is a carbonate mineral that often forms from calcite. Sometimes liquids rich in magnesium carbonate (MgCO 3) (an atom of magnesium, an atom of carbon and three atoms of oxygen) pass through a limestone.When this happens, the CaCO 3 of the calcite picks up the MgCO 3, so forming dolomite.

What happens when acid reacts with …

Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will
