Valuation Of Calcium Carbonate Quary

Using Ground Eggshells as a Material in Corn and

eggshells have value as a source, and if so, at what rate equivalent to quarry limestone should they be applied. Eggshells are comprised mainly of calcium carbonate (94 to 97%), which should neutralize soil acidity. However, studies with soil application are quite limited. In 1994, Mitchell evaluated the usefulness of ground eggshells as a
