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.
surface and nitrogen use efficiencies can be as low as 20 lbs of additional forage per lb of N applied. The value of grass hay can vary considerably with cow hay selling for $120 to $150/ton and horse. hay in small bales selling for $180 to over $200/ton at present. Two other costs that need to be. figured into the calculations are the cost to apply the fertilizer, which I put in at $8.00/ac, and the cost.
