Lime Kiln Dust / Calciment ® LKD is a coproduct of lime manufacturing. Lime is created when high quality, natural deposits of limestone, or calcium carbonate (CaCO3) is subjected to extreme heat. Once crushed and sized, the limestone is fed into kilns where it is calcined, or basically cooked, at temperatures as high as 2000 degrees Fahrenheit.
Lime is a soil amendment consisting mainly of processed limestone in pulverized, powdered, or pelletized form. Its chemical form is comprised of an inorganic salt, calcium carbonate. ... Soil acidification occurs naturally, especially in warm climates with high rain. This degradation occurs faster in areas with soil comprised of clay and sandy ...
