The Dolomite Mountains were named after the mineral. For larger, commercial fields, it’s generally advisable to send a sample off to a professional testing company for a readout. Homeowners however can usually get away with purchasing a home testing kit. Once you’ve concluded that your soil’s pH needs to be elevated, you should start considering the right solution for your needs. AGRICULTURAL LIME 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. Because of this, it’s very important to make plans to spread aglime across affected areas in advance. The best time to till aglime into the soil is at the end of the growing season. This will give the material enough time to be absorbed into the soil and react before the following planting season. Because dry lime is so small in particle size, it can be blown in the wind, so it should be applied in calm weather conditions.

Dolomite is widespread in its occurrences, though not as common as limestone. [20] It is typically found in association with limestone or evaporite beds and is often interbedded with limestone. [21] There is no consistent trend in its abundance with age, but most dolomite appears to have formed at high stands of sea level. Little dolomite is found in Cenozoic beds (beds less than 65 million years old), which has been a time of generally low sea levels. [22] Times of high sea level also tend to be times of a greenhouse Earth, and it is possible that greenhouse conditions are the trigger for dolomite formation. [23] 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]

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. Different types of fruits and vegetables require varying acidity and nutrient levels. Knowing what you want to plant in your garden and researching their ideal soil pH and nutrient levels can also help you decide what type of lime, if any, to use. Rich source of magnesium: Fields that are home to crops taxing on potassium levels — such as corn fields — can benefit from magnesium treatments. If your field contains a calcium-to-magnesium ratio of 6:1 or greater, it is considered to be magnesium deficient, and you should strongly consider using dolomite lime to balance your minerals. Proper calcium-to-magnesium ratios are important for ensuring healthy growth.This describes how acid or alkaline soil is, and is expressed as a number between 0 and 14. Soil with a pH of 7 is neutral, an acid soil has a lower value, and an alkaline soil has a higher one. Most plants grow best in soil that’s within a specific pH range, so it’s useful to know your soil’s pH. Testing kits are easy to use and widely available in garden centres and online. pH before planting or sowingis recommended.

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.

Geosciences 3(3):89–98. https://doi.org/10.5923/j.geo.20130303.02 Aglime and dolomite both become useful when soil becomes too acidic. This typically occurs after exposure to acid rain, after frequent use of fertilizers and other chemicals or even after the soil has simply become deprived of important nutrients from years of planting and harvesting crops.These all-natural stone products have proven themselves to be to be invaluable to the agricultural industry, as well as in residential applications throughout the centuries. Nevertheless, even though both materials have been around for a long time, there is still a lot of confusion about which should be used for what purposes and when. If both agricultural lime and dolomitic lime are capable of raising the soil’s pH level from acidic to nearly neutral, which option is best for your needs? Fortunately, coming to the right answer is not as difficult as you might imagine. First, you’ll need to know what type of soil you’re working with.
