Amending Soils with Lime or Gypsum (NRCS 333) AgBMPs

Dolomitic limestone is a combination of calcium (55-85%) to magnesium (45-15%) carbonates. Calcitic limestone is predominately calcium (95%) but still contains a small amount of magnesium (5%) carbonates. A variety of materials have neutralizing capabilities but are generally less effective, more costly than or not as available as limestone. Gypsum
