The rubble is then hauled to a crushing facility where the stone is further crushed, screen-sorted into size classes, and stored. Limestone needed for high-purity applications quicklime and food supplements is usually hand-sorted at the mine. The process is called calcination and works by driving off carbon dioxide from the calcite, forming calcium oxide quicklime.
Limestone used as a source of nutritional calcium is simply ground into a powder, mixed with other supplements and binders, and reformed into pills or capsules. Stone that is to be used for its ornamental qualities is extracted from the bedrock by saws and wedges. Afterwards, the rock is either cut or carved to its final shape. Polishing may be used to finish the product. No records of annual production of limestone and dolostone are readily available from Arkansas because they are grouped with other types of rock aggregate production, but yearly production tonnage is significant.

If you have serious concerns about which type of lime to use based on soil test report information, feel free to contact your local Michigan State University Extension educator for research-based information before you invest in the application.

Should I use dolomitic or calcitic lime? The short answer? Very unlikely. However, if a crop requiring a low pH is being grown and liming is not recommended, gypsum can supply calcium to the crop.
If liming is required, a dolomitic or calcitic liming material will supply sufficient calcium to maintain crop growth. Dolomitic lime sources have the added benefit of increasing available magnesium. Dry lime is more efficient and more affordable. It works better with most agricultural equipment and is easier to transport. If you are looking to complete a large agricultural application, dry lime will likely make more financial sense.
With a good dry lime application, you can balance your pH without repeat applications, but the results may not be noticeable for up to a year. So if you are looking for a quick pH rebalance, you should consider damp lime: If you want to see immediate results, perhaps because you are renting your fields, and are less concerned about long-term results, damp lime could be the best solution.
However, if you have a large field and the means to apply one thorough lime treatment every year, dry lime will be better for you in the long run. The higher concentration of lime means the soil will be more completely treated, even if it does take a little bit longer to take effect.
In addition to choosing between dry and damp lime, you can also choose between pulverized 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. Pelletized lime is especially good for garden use.
It is easier to spread if you do not have large scale agricultural equipment. Pelletized lime also tends to react more quickly, as it more thoroughly processed before it is pelletized.
Pelletized lime is less subject to windy and dry conditions: Pulverized lime is best applied during moist weather, as wind and dry conditions can cause the lime application to blow around and become less evenly applied. However, because pelletized lime is more processed, it also tends to be more expensive by weight. If you are distributing a small amount of lime, such as in a small garden, the difference in price should not be noticeable. Deciding whether calcitic lime or dolomite lime is best for you can be difficult.
If you are having trouble deciding, you can contact a Baker Lime representative to discuss your options. Our professional and friendly consultants have years of experience helping farmers and gardeners till healthier and more productive soil.
And if you already know which type of lime you need for your fields, find and contact one of our reps today to place an order. Regardless of which kind of lime you need in order to improve the pH level in your fields, Baker Lime has the product you need. Because both calcitic lime and dolomite lime can drastically change the mineral make-up of your fields, you want to be sure that you are getting the product that is best suited for your needs.
Calcitic lime is the standard treatment. It balances pH efficiently while also encouraging the growth of plant-healthy micro-organisms. But if your fields are also magnesium deficient, which is especially common in sandier soils, only dolomite lime will raise the magnesium levels.
This is especially important if your fields are used for livestock grazing, as magnesium deficiency can negatively affect your herd. If you have a larger field, dry, pulverized lime will probably be the most cost efficient. However, if you do need to quickly correct an extreme acidity in your soil, then damp lime may be best. Additionally, if you have a small garden without large agricultural equipment , you should consider pelletized lime, as it is easier to apply by hand.
Limestone was most famous during the 19th and 20th century as many public buildings and structures were made from limestone. As raw material in the manufacture of cement and mortar , crushed as a solid base for roads, added as white pigment in medicines, cosmetics, toothpastes, paper, plastics etc.
The way dolomite is formed is not quite clear, and it has been found that it forms under high saline conditions in environments like lagoons. Dolomite is also a sedimentary rock type. When dolomite is formed, several steps of dissolution and re-precipitation is passed where the structure of the mineral is modified into more stable forms and crystallizes in a trigonal-rhombohedral manner.
Dolomite crystals are usually white or greyish pink in colour, yet the presence of certain impurities can bring a colour change; i. Iron in dolomite gives it a yellowish brown tint.
