You can also use dolomite lime when a bit more calcium and magnesium are in demand. Certain fruits and vegetables, such as tomatoes, require more calcium as they grow. Dolomite lime will provide both calcium and magnesium, making it beneficial for other vegetables like parsnips, onions, beans, and garlic, too.

When applying less than 0.5kg per sq m (14¾oz per sq yd), dig the entire amount in, but you can sprinkle it on the surface if digging is not practical.

Technically, you can apply lime to your garden any time as long as there is no frost, snow, or freezing temperatures. That said, spring and fall are the best times, your plants get to receive the maximum benefit.

Types of lime binders in mortars used for the construction of the Ming Great Wall of China and their importance for the development of a conservation strategy In addition to choosing between dry and damp lime, you can also choose between pulverized dolomitic limestone and pelletized lime. Each have their applications, so depending on your needs, you will find either one or the other better suited for your use.How much dolomite lime per gallon of soil is a crucial question to answer before adding any amount of lime to your garden? Testing can be done at any time, but if carried out within three months after adding lime, fertiliser or organic matter, the test may give misleading results. If you’re adding dolomite lime for the benefit of added calcium and magnesium, you should apply it around two to three weeks before planting. This will give the compound enough time to break down in the soil to give your plants the boost they need. You’re also free to add more once the plants have been planted, too. Particularly dense microstructures and high compressive strengths at specific points can be measured on mortars made from dolomitic limestones, which are not described in more detail here.

Combined with material descriptions and sample mappings, the following standard methods of mineralogical and chemical analysis were used to determine whether the binders can be characterised systematically. Approximately 40 samples were selected for chemical-mineralogical analyses. An average of five specimens served as comparative samples of the respective findings. The XGW lime mortars based on calcium-rich lime binders show lower bulk densities ranging between 1.1 and 1.2 g/cm 3. They are more porous than dolomitic lime mortars, and the capillary porosities of calcium-rich lime mortars are on average 45% by volume and 50% by volume. These values also correspond exactly to the unpublished results of the previously examined larger series of mortars of calcium-rich lime binders of the Great Wall. Compressive strengths of comparative samples could be measured > 6 MPa, lower than those of dolomitic lime mortars, but still relatively high for lime mortars with very low levels of hydraulic components. 4.5 Results of salt analyses and observed damageThe effectiveness (called the ‘Neutralising Value’ (NV)) is expressed as a percentage of the neutralising value of pure calcium oxide (which is caustic so cannot be used). The NV varies between materials – typical examples include: Special attention was given to possible secondary phase formations, reaction zones between binder and aggregate grains, and identification of hydraulic phases. Again, it’s important to actually conduct a soil test (testing for both pH and nutrient content) before you add dolomite lime to the garden.

The results of bulk densities and capillary water absorption from selected mortars are reported in Table 1. The bulk densities of approximately 1.7 g/cm 3 are in the range of unpublished values of bulk densities of typical dolomitic lime mortars from Beijing with measured maximum values of 1.8 g/cm 3. Compared with those mortars, SMT and JMY correspond to low porosities with values of approximately 18% by weight and 30% by volume. Ultrasonic velocities of 800 m/s and comparatively high compressive strengths > 7 MPa were measured on individual samples. Dai, Shibing, Yan Zhong, and Zhanyong Hu. 2016. Ten questions on lime work - lime Technology for Built Heritage Conservation. Shanghai: Tongji University Press. Calcitic lime for lawns has long been the preferred treatment for acidic soil. A thorough application of pulverized limestone tilled into the soil raises the pH to a neutral level, increasing crop yields and improving overall soil health.

Another model is the mixing-zone or Dorag model, in which meteoric water mixes with seawater already present in the pore space, increasing the chemical activity of magnesium relative to calcium and causing dolomitization. The formation of Pleistocene dolomite reefs in Jamaica has been attributed to this process. However, this model has been heavily criticized, [26] with one 2004 review paper describing it bluntly as "a myth". [27] A 2021 paper argued that the mixing zone serves as domain of intense microbial activity which promotes dolomitization. [28] Although dolomitic lime performed remarkably well during the construction period of the Ming Great Wall, it is not recommended as a binder for restoration mortars. One reason is that there are no manufacturers or technicians who can handle dolomitic building lime. Another argument is the durability of dolomitic lime under present conditions of air pollution. Calcium-rich lime such as CL90 could be more suitable as a binder for bedding and repointing mortars. Due to its very slow carbonation in built masonries and its associated low strength and low resistance to frost, calcium-rich lime such as CL90 without pozzolanic addition is not recommended for structural consolidation (Historic England 2012 and 2017). International studies on dolomitic lime have shown that high sulfate-resistant hydraulic binders are preferred for structural conservation. An alternative might be formulated lime, i.e., high calcium lime gauged with natural pozzolan. In some samples of both groups, XRD identified aragonite, which can be seen as an indication of the decomposition of carbonated C-S-H phases with the products of aragonite and silica gel (Diekamp 2014). 4.3 Results of microscopic analyses 4.3.1 Dolomitic lime mortars from Beijing Province using Simatai SMT and Jiangmaoyu JMY as examples Dolomite outcrops are recognized in the field by their softness (mineral dolomite has a Mohs hardness of 4 or less, well below common silicate minerals) and because dolomite bubbles feebly when a drop of dilute hydrochloric acid is dropped on it. This distinguishes dolomite from limestone, which is also soft but reacts vigorously with dilute hydrochloric acid. Dolomite usually weathers to a characteristic dull yellow-brown color due to the presence of ferrous iron. This is released and oxidized as the dolomite weathers. [14] Dolomite is usually granular in appearance, with a texture resembling grains of sugar. [15]
