Rest of the limestone is used in paper, sugar, fertilizers, etc.Soil erosion, soil nutrient depletion and soil acidity associated to Aluminium (Al) toxicities are the main soil related constraints to agricultural ...Limestone is a sedimentary rock, although it has a hardness of 3-4 Mohs and a density of 2.5 to 2.7 grams per cubic centimeter. The rock is primarily composed of calcite or calcium carbonate, with most of these rocks being around 95% calcium carbonate. Being so high in calcium makes limestone rock polish and smooth better.
