Q: Is aglime the same as lime? A: No. The term agricultural lime, or "aglime," usually refers to crushed limestone. Limestone (calcium carbonate) is not the same as hydrated lime (calcium hydroxide).

What kind of lime is used for agriculture?

Types of Lime for Agricultural Crops Lime is available as magnesium or calcium additives. Magnesium-based lime is called dolomitic lime. Calcium-based lime is called calcitic lime. Depending on your soil's specific deficiency, it may require one type of lime or the other.

Is garden lime good for all plants?

According to Rural Living Today, garden lime is used to raise soil's pH level. Chemicals, metals, and other elements can make soil too acidic for many plant species and the application of lime can reduce the pH to workable — even ideal — levels. However, not all plants require this type of intervention.

Can I use garden lime instead of hydrated lime?

In contrast, hydrated lime is up to 1.5 times more effective at quickly raising the pH level than the commonly used agricultural limes. Because it does not provide magnesium, gardeners with an excess amount of that nutrient in their garden soils might find hydrated lime preferable to commonly used garden limes.

What do you use garden lime for?

Garden lime is a rock powder used to raise the pH level of soils high in acidity. An application of lime "sweetens" a soil -- that is, it can make a "sour" soil more alkaline. Why might you wish to bring about such a change in the ground in which you are planting?

What is the difference between garden lime and barn lime?

What is agricultural lime?

Agricultural lime, also called aglime, agricultural limestone, garden lime or liming, is a soil additive made from pulverized limestone or chalk. The primary active component is calcium carbonate. Additional chemicals vary depending on the mineral source and may include calcium oxide. Unlike the types of lime called quicklime (calcium oxide) and slaked lime (calcium hydroxide), powdered limestone does not require lime burning in a lime kiln; it only requires milling. All of these types of lime are sometimes used as soil conditioners, with a common theme of providing a base to correct acidity, but lime for farm fields today is often crushed limestone. Historically, liming of farm fields in centuries past was often done with burnt lime; the difference is at least partially explained by the fact that affordable mass-production -scale fine milling of stone and ore relies on technologies developed since the mid-19th century.

What are the effects of lime on soil?

Some effects of agricultural lime on soil are: it improves the uptake of major plant nutrients ( nitrogen, phosphorus, and potassium) of plants growing on acid soils. Other forms of lime have common applications in agriculture and gardening, including dolomitic lime and hydrated lime.

Why is limestone a CCE?

Because each molecule of magnesium carbonate is lighter than calcium carbonate, limestones containing magnesium carbonate ( dolomite) can have a CCE greater than 100 percent. Because the acids in soil are relatively weak, agricultural limestones must be ground to a small particle size to be effective.

How does lime affect strontium?

A 2019 study demonstrated that agricultural lime affects strontium-based mobility studies, which attempt to identify where individual prehistoric people lived. Agricultural lime has a significant effect in areas with calcium-poor soils. In a systematic study of a river system in Denmark, The Karup River, more than half of the strontium in the river's catchment area was found to come from runoff of agricultural lime, and not from the surrounding natural environment. Such introduction of agricultural lime has resulted in researchers wrongly concluding that certain prehistoric individuals originated far abroad from their burial sites, because strontium isotopic results measured in their remains and personal effects were compared to burial sites contaminated by agricultural lime.
