Dolomite Lime (Calcium Magnesium Carbonate ) is a soil conditioner made from crushed limestone. This agricultural dolomite has 21.8% calcium, 54.7% calcium carbonate and 11.6% magnesium, 40.2% magnesium carbonate. Its calcium carbonate equivalent is 103%. The benefits of agricultural lime include: Improving the physical, chemical and biological properties of the soil Promoting better nitrogen fixation by legumes Increasing the availability of nutrients to plants Reducing toxicities in the soil Enhancing the effectiveness of some herbicides Supplying calcium, magnesium and other minerals to crops Raises pH in acidic soil RESOURCES Dolomite Lime Heavy Metals Test
