The research suggesting that the Ca:Mg ratio might be significant began in 1901 and is pretty old science. Since then there have been new developments and consequently a better understanding of the fate of soil nutrients. This work has proved the experimental design of these older trials were flawed and that there is a much wider range of Ca:Mg ratios that are acceptable. These “authorities” who collectively have 1000’s of years experience in research regarding soil science are providing the best explanation of this incredibly complex ecosystem that we have yet. I’m not saying all old research is flawed but we did once think the world was flat. I’m not sure why gardners get so emotional about Ca:Mg ratios. After doing nutrient management plans I have found that using the base saturation concept to try to balance soil ratios actually costs much more than going with a sufficiency approach. I suppose that makes the corporations happy that are selling the soil amendments that are needed to try to get the “right ratio”. I don’t think there is much harm in trying to balance these ratios but you will unnecessarily spend more on soil amendments. Yes, I agree the system has been corrupted. The laws of economics put an incredible amount of pressure on our farmers and they do become trapped in a system where they feel they need to use available technologies to guarantee a crop and mitigate risk. I’m not sure what all of that has to do with Ca:Mg ratios but I would be very interested in seeing your research on the topic. Dettmering, Tanja, and Helmut Kollmann. 2019. Putze in Bausanierung und Denkmalpflege, 3. überarbeitete Auflage. Berlin: Beuth-Verlag. To obtain information about the physico-mechanical properties, the bulk density and capillary water absorption relevant to building physics were determined. As the light microscope can visualise voids with a size of > 10 − 6 m, only a few capillary pores (10 − 5 m – 10 − 8 m) are visible. To obtain reference values for compressive strengths, only some (sufficiently large) specimens were tested. Their ultrasonic velocities were determined to estimate the dynamic elastic modulus. 3.2 Salt analyses People often wonder does dolomite lime raise ph? Well, yes! Moreover, adding dolomite lime to the soil becomes necessary when the pH level is too low. But how can you add dolomite lime? Let’s have a look at the procedure of its application:
Dolomite lime is harvested from underground limestone deposits. It contains good doses of both calcium carbonate and magnesium carbonate. When harvested, the dolomite lime crystals can be gray, white, tan or pink in color. However, there are some differences between the two. For example, dolomite lime contains magnesium (in the form of magnesium carbonate), while lime (calcite lime) does not. All in all, the Dolomite Lime pH Stabilizer is added to reduce the acidity of the soil. If the pH of the soil is low (Acidic), then there must be some sort of treatment a grower must apply. Failure to do so will directly impact the plant. For the Treatment, lime is generally added. Dolomite lime is widely used which can neutralize acidity effectively. On top of it, this lime can also add magnesium to the soil. But make sure the soil is also magnesium deficient as the magnesium-enriched soil further causes problems like compaction. So, do smart gardening and know what is best for your plants History [ edit ] Cristallo in the Dolomites mountain range near Cortina d'Ampezzo, Italy. The Dolomite Mountains were named after the mineral.Elsen, Jan. 2006. "Microscopy of historic mortars – A review." Cement and Concrete Research 2006 (36): 1416–1424. https://doi.org/10.1016/j.cemconres.2005.12.006. The mineral dolomite crystallizes in the trigonal-rhombohedral system. It forms white, tan, gray, or pink crystals. Dolomite is a double carbonate, having an alternating structural arrangement of calcium and magnesium ions. Unless it is in fine powder form, it does not rapidly dissolve or effervesce (fizz) in cold dilute hydrochloric acid as calcite does. [9] Crystal twinning is common.
Chemically, both lime mortars have almost the same composition. The average CaO contents of mortar samples from SMT and JMY range from 30 to 31 wt.%, and MgO contents range from 15 to 21%. The binder contents are almost stable, 90–91 wt.%. This also corresponds to today’s dolomitic limes DL90-30. So if you add dolomitic lime to your lawn/garden every year, chances are you’re just causing more compaction and weed problems. Here’s What My Books Say
Adding Dolomite Lime To Water
Do a soil test before adding the Dolomite lime. This will give you an idea what is the pH of the soil and whether the soils are deficient in magnesium or not. Home test kits are also available but these only tell about the percentage of Nitrogen, Phosphorous, and Potassium in the soil along with the pH. To get a detailed analysis and of the percentage of magnesium present in the soil, we recommend you go for lab tests. Kuhl, Oliver. 2019. "Basic principles for soil treatment with binder – Stabilization of fine-grained soil with lime." Paper presented at the Joint Annual Meeting & International Conference on ICOMOS -CIAV&ISCEAH, Vernacular & Earthen Architecture towards Local Development, Pingyao, September 6–8. Let’s get this clear, to determine how much dolomite lime per gallon of soil depends on the pH level of your soil. If you have not carried out the soil tests, it is safe to apply the dolomite lime at a ratio of 1 cup (250ml) for every 15 square meters or 50 square feet garden.
Therefore, if you use hydrated lime, you will need much less than products containing calcium carbonate.Historic England. 2008. Conservation principles, policies and guidance.

For the construction of the Great Wall around Beijing, in Zunhua, east of Beijing, lime mortars consisting of approximately 5–22 wt.% MgO were used (Dettmering and Dai 2021; Wang 2021). Based on chemical analyses, they can be classified as dolomitic limes according to modern lime classification.
