(natural limestone) and 130.4 €/tCO 2 (dolomite). Although doped limestone has shown a CO 2 avoided cost of 117.7 €/tCO 2, this can be reduced if the production cost of doped limestone is lower than 42.6 €/t. The production costs of new sorbents for CO 2 capture and H 2 production need to be similar to that of natural limestone

FAQ: Dolomite and Limestone 1. Is dolomite better than limestone? When comparing dolomite to limestone, dolomitic limestone is often preferred because it has a harder composition. This hardness makes it more resistant to wear and erosion, which makes it a better choice for applications where durability is essential, like construction …

To know the pH of the soil, a soil test is recommended. You can also use pH soil strips as well to know the pH. However, for some reason, if you don't do a soil test and have no idea what is the pH of the soil, then dolomite is added in this ratio: Apply one cup of Dolomite lime for 15 square meters (50 square feet).
