In general, the best time to lime your lawn will be in the fall. This will give the lime plenty of time to transform your acidic soil before the next growing season,' explains Chris.
As the name suggests, dolomitic lime is manufactured by crushing dolomitic limestone down to very small pieces. As with agricultural lime, dolomitic lime works to increase the pH levels of acidic soil and return the earth to nearly neutral.

Beyond this, the introduction of dolomitic soil (which contains a 2:1 magnesium to calcium ratio) can actually cause more problems to the earth than what it’s worth. Excessively high magnesium levels have been known to create issues with soil compaction, the introduction of a high volume of weeds, and increased difficulty in water properly being absorbed into the ground and into the plants.
Hamza M (2017) The troublemaking soils of Egypt. Underground Infrastructure and Deep Foundations. Cairo, Egypt Before you can even begin to think about whether agricultural lime or dolomite could benefit your soil, you first need to have an understanding of when these materials are actually necessary. Magnesium and calcium carbonate work together to create the needed conditions for certain types of plants. However, too much magnesium in your soil can cause problems. For that reason, it can be safest to use dolomite lime only when you know your soil has a magnesium deficiency or when the plants you’re growing need extra magnesium. Choosing Lime for Your Garden Certain plants, such as tomatoes, onions, and garlic, require more magnesium to thrive. You can add dolomite lime to planters where you plan to grow these plants, or skip the hassle and invest in a GrowBox, which comes pre-balanced with dolomite lime. Planting your tomatoes, onions, and more in a GrowBox ensures that the plants get the nutrients they need. Soil Hydration Lamar, J.E. (1961). "Uses of limestone and dolomite" (PDF). Illinois State Geological Survey Circular. 321 . Retrieved 15 September 2021.I touched on this before when I talked about pH. The belief is that minerals in your soil are continuously being leached by rain and consequently your soil is always moving towards more acidic. 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. Quantities to apply Plus, if you don’t need dolomite lime to incorporate magnesium, calcitic lime works better at restoring pH. Even though magnesium carbonate is alkaline just like calcium carbonate, it doesn’t work quite as effectively. So if you are merely looking to correct the pH balance, you are much better served choosing calcitic lime. Boggs, Sam (2006). Principles of sedimentology and stratigraphy (4thed.). Upper Saddle River, N.J.: Pearson Prentice Hall. pp.160–161. ISBN 0131547283. To know how acidic your soil is, you’ll need to test its pH level. You can do this with a home test or hire a professional to do it.
dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate [CaMg(CO 3) 2]. General considerations The dolomite of most dolostones is granular, with the individual grains ranging in size from microscopic up to a few millimetres across. Most dolomite marbles are coarsely granular with individual grains ranging between 2 and 6 millimetres (0.079 and 0.24 inch) in greatest dimension. Vein dolomite grains may be up to several centimetres across. Saddle-shaped groups of dolomite crystals, most of which occur on fracture surfaces, measure from 0.5 to 2 centimetres (0.20 to 0.79 inch) across. Origin and occurrencePoor lime is also known as lean or meager lime. Poor lime sets and cures very slowly and has weak bonding. Poor lime is grey in color. In addition to neutralizing your acidic soil, the benefits of dolomitic lime include the following:
It is possible that microorganisms are capable of precipitating primary dolomite. [7] This was first demonstrated in samples collected at Lagoa Vermelha, Brazil [6] in association with sulfate-reducing bacteria ( Desulfovibrio), leading to the hypothesis that sulfate ion inhibits dolomite nucleation. Later laboratory experiments suggest bacteria can precipitate dolomite independently of the sulfate concentration. [36] With time other pathways of interaction between microbial activity and dolomite formation have been added to the discord regarding their role in modulation and generation of polysaccharides, [37] manganese [38] [39] and zinc [40] within the porewater. Meanwhile, a contrary view held by other researchers is that microorganisms precipitate only high-magnesium calcite but leave open the question of whether this can lead to precipitation of dolomite.
