Commodity: Limestone, a sedimentary rock that is dominantly composed of the calcium-bearing carbonate minerals calcite and dolomite. Calcite is chemically calcium carbonate (formula CaCO3). Dolomite is chemically calcium-magnesium carbonate (formula CaMg(CO3)2).n calcite, carbonate is chemically combined with calcium to form calcium carbonate (formula CaCO3). In dolomite, carbonate is chemically combined with calcium and the element magnesium (symbol Mg) to form calcium-magnesium carbonate (formula CaMg(CO3)2).
That is as little as $10.00 to $15.00 for mix grass baled in 1,000 to 1,200 round hay bales. The going price in my area to cut, rake, and bale this hay in 1,000 to 1,200 pound rolls is $10.00 per bale. Wow! Kentucky farmers are making a killing, if they sell these round hay bales for $10.00.
The heaviest type of bale is a round bale, and the lightest a square bale. Large round bales are always heavier than small squares. Large round bales of hay can weigh up to a tonne (2200 lbs), and small square bales will typically weigh around 50 to 75 lbs. Large squares can weigh around half a tonne or more (~1000 lbs).
