While liquid lime will react faster and can be more evenly spread, however, it is also more labor intensive and liquid lime will need to be applied more frequently than dry lime.

Diyarbakır, Turkey Dolomitic lime is calcium magnesium carbonate. It has something like 20% calcium and 10% magnesium, but that can vary quite a lot.

dolomite, type of limestone, the carbonate fraction of which is dominated by the mineral dolomite, calcium magnesium carbonate [CaMg(CO 3) 2]. General considerations Magnesium lime contains more than 5% magnesium oxide (BS 6100) or 5-35% magnesium carbonate (ASTM C 59-91). [15] Dolomitic lime has a high magnesium content of 35-46% magnesium carbonate (ASTM C 59-91). [15] Dolomitic lime is named for the Dolomite Mountains in the Italian and Austrian Alps.

(more) In dirt with acidity above pH 6.5, there may be deficiencies in nitrogen, phosphorus, potassium, magnesium, or molybdenum. In addition, nutrients like aluminum, iron, and magnesium may become toxic in the presence of excess acidity.The best case for dolomite lime use is when soil is magnesium deficient. If the ratio of calcium to magnesium in the soil is 6:1 or greater, then your soil is magnesium deficient. In these conditions, plants and grass will grow weakly, will yellow, and will not develop deep roots. Applying calcite lime to magnesium-deficient soil will only aggravate this problem. Dolomite lime can, however, correct magnesium deficiency.

To avoid disaster, you should always carefully measure your soil’s magnesium levels before selecting dolomitic lime. CHOOSING THE RIGHT LIMING AGENT You may also come across liquid lime (chelated calcium) for spraying directly onto the foliage of calcium-deficient plants. The main “ingredient” in calcitic lime is calcium carbonate, which is why many people ask if calcium carbonate is the same as limestone. It counteracts the acidification of field soil. Acidification is the natural result of nitrogen heavy fertilizing practices. By adding a lime treatment, you can undo the damage caused by nitrogen treatments without counteracting the benefits. What are The Benefits of Calcitic Lime? Whatever the cause, dolomite lime fertilizer is usually not the answer. Let’s look at why this form of garden lime is probably not what you want. Here’s The Important Part Pellets tend to be pricier, and they are made with a binding agent that must break down before the lime can work its way into the earth. The plain pulverized version is generally cheaper and breaks down faster. However, it is such a fine powder that the slightest breeze makes it airborne and poses an inhalation risk.

If you live on the East Coast like I do, there’s enough rainfall to cause alkaline nutrients to leach out of the dirt, thereby increasing its acidity. As you travel west, dirt tends to be more alkaline. Fertilizer Nelson JD, Miller DJ (1992) Expansive Soils, problems and practice in foundation and pavement engineering. Wiley, New York

According to Dr. Stanley Barber, Purdue Univ., “There is no research justification for the added expense of obtaining a definite Ca:Mg ratio in the soilResearch indicates that plant yield or quality is not appreciably affected over a wide range of Ca:Mg ratios in the soil.”Wisconsin research found that yields of corn and alfalfa were not significantly affected by Ca:Mg ratios ranging from 2.28:1 to 8.44:1in all cases, when neither nutrient was deficient, the crops internal Ca:Mg ratio was maintained within a relatively narrow range consistent with the needs of the plant. These findings are supported by most other authorities. A soil with the previously listed ratios would most likely be fertile. However, this does not mean that a fertile soil requires these specific values (or any other). Adequate crop nutrition is dependent on many factors other than a specific ratio of nutrients. It will rarely be profitable to spend significant amounts of fertilizer dollars to achieve a specific soil nutrient ratio. 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. Before you begin an in-depth exploration of which lime treatment option is best for you, you need to determine your soil needs.Our Dolomite Lime Bags are the ideal way of increasing soil pH to 6.5, which is a safe pH for most plants including: brassicas, legumes and grasses, okra, peppers and celery. Applying Dolomite lime boosts plant growth and provides Magnesium and Calcium, which aids in the creation of seeds in fruits, as well as allowing for photosynthesis to occur. Calcium on the other hand, prevents plants from growing incorrectly, and allows proper cell wall formation, leading to sturdier and healthier plants. Before using this product it is recommended to test your soil pH level and nutrients. Too much calcium and magnesium could damage plants. Whilst a soil pH being too high or low could cause problems for a lot of plants. Davidson DT, Handy RL (1960) Lime and lime-pozzolan stabilization. Highway engineering handbook.
