  • Understanding Plant Nutrition: Limestone, Calcium And

    Jun 10, 2008· Limestone Nutrient Content There are four types of carbonate-based limestone that are available. Calcite is pure calcium carbonate (CaCO 3, 40 percent Ca).Calcitic lime is composed of mostly CaCO 3 (> 30 percent Ca) with some MgCO 3 (<5 percent Mg). Dolomitic lime contains less CaCO 3 (<30 percent Ca) and more MgCO 3 (>5 percent) than calcitic lime. Finally, dolomite also

  • Limestone Quality Calculator
