What is agricultural lime?

Often referred to as “aglime“, agricultural lime is simply limestone that has been pulverized down to a fine particle size and introduced to acidic soil. Lime is selected because it contains such a high amount of calcium, which works to neutralize the soil’s pH levels.

Are all lime products made the same?

However, not all lime products are made the same, and within this group of products there is one form that consistently stands out as an exceptional solution: pelletized limestone. The benefits of applying a lime soil amendment are a result of lime’s ability to correct soil acidity.

What is the difference between agricultural lime and dolomitic lime?

As with agricultural lime, dolomitic lime works to increase the pH levels of acidic soil and return the earth to nearly neutral. The primary difference between the two materials is that, in addition to containing calcium carbonate, dolomitic lime also contains a mixture of magnesium carbonate.

Is lime a good fertilizer?

Limeis a soil amendment made from ground limestone rock, which naturally contains calcium carbonate and magnesium carbonate. Even though limeincludes calcium and magnesium, which are essential nutrients for healthy plant growth, it’s not a substitute for fertilizer. Is Lime a nitrogen fertilizer?


Why is lime important to soil?

The practice of applying Lime is integral to increasing soil fertility and productivity. Most vital nutrients required for plants to thrive (like nitrogen, phosphorus, and potassium) become bio-available when the soil is at a neutral level of 7 pH. Soils can become acidic in a variety of ways: from excessive levels of rainfall, mineral loss due to crop removal, and, most notoriously, when modern chemical fertilizers are used. A proper application of Lime is one of the quickest ways to rectify acidic soils.

What is the difference between ag lime and dolomitic lime?

Notably the biggest difference between Agricultural Lime and Dolomitic Lime is that Ag Lime is primarily composed of calcium carbonate whereas Dolomitic Lime is a blend of calcium carbonate and magnesium carbonate.

What is a liming soil?

Agricultural Lime. Liming the soil is an important and traditional agricultural practice that involves remineralizing the rhizosphere. Both Agricultural and Dolomitic Lime have the ability to neutralize acidic soils.

How to fix acidic soil?

A proper application of Lime is one of the quickest ways to rectify acidic soils. When either kind of Lime is introduced into your soil, the soil can become more porous, which will increase air circulation and the ability of the soil to absorb and hold moisture.

What is the purpose of lime in agriculture?

The objective of agricultural lime on soil is to raise the PH level, thereby decreasing the acid present in it. By increasing the alkaline level and mitigating acid the soil has a better chance of producing vibrant crops.

What is pulverized limestone?

The pulverized limestone that constitutes agricultural lime is an organic matter that neutralizes soil acidity.

Why is my soil acidic?

Chances are that the soil in your field or garden will become acidic over time due to several factors, including decomposition of organic material and erosion. Limestone raises the pH level to a neutral range beneficial to plants, typically between 5.5 and 6.5.

How to restore pH balance in soil?

But how can you successfully restore a proper PH balance to your soil? The solution is soil additives. There are two options for this means of mitigation: agricultural lime (aglime) or gypsum.

Why does soil erode and deteriorate?

Why does soil erode and deteriorate this way in the first place? It’s a natural process that occurs over time. Wind, rain, and tilling are all factors that contribute to the degradation of soil quality.

How does acid affect plants?

Just how significant is the impact of acid on plant growth? Greater than one might imagine. The reduction of nutrient absorption caused by acid sharply limits the extent to which a plant can grow. In fact, too much acid can even lead to unbearable toxicity levels in the soil which can be fatal to plants.

Why is calcium important for plants?

Calcium, on the other hand, is critical to the growth of cell walls within plants. Why does this matter? The cell wall, among other things, will help to improve the nutrient absorption of the plant.

Why is lime used in agriculture?

Ultimately, applying lime to agricultural crops will eliminate the state of toxicity that the plants are experiencing. Acidic soil is toxic for plants.

How does lime help the soil?

Agricultural lime helps lower the soil’s acidity levels by rendering it more pH neutral. By applying lime to the soil when it becomes too acidic, farmers can ensure they are helping improve their crop output. If crops can’t properly grow, they can’t produce, which impacts the agriculture business and its bottom line.

How does lime affect soil pH?

By applying agricultural lime to crops, you can help to increase the soil’s pH level by neutralizing and reducing the levels of manganese and iron that cause soil to become acidic. Lower manganese and iron levels can help to reduce the risk of plants becoming toxic, which helps increase their growth and output rates.

What happens when you use lime in acidic soil?

When the right type of agricultural lime is appropriately applied to acidic soil, the crops that were once facing toxic conditions will begin to benefit from the change in pH levels. Plant roots will benefit from the calcium and/or magnesium supplementation. Roots will become more efficient at nutrient uptake.

What is the difference between magnesium and calcium lime?

Depending on how acidic the soil has become, there are different types of lime products to use. Lime is available as magnesium or calcium additives. Magnesium-based lime is called dolomitic lime. Calcium-based lime is called calcitic lime.

Why is lime important?

It is important to get in the habit of applying lime to crops as needed in order to keep the pH levels stabilized. Otherwise, not having lime applied to crops when needed can perpetuate acidic conditions and reduce crop output. Agricultural lime should be an important consideration in any nutrient management plan.

How to fix acidic soil?

In order to remedy the problem of acidic soil, lime can be applied to crops to raise the pH levels by adding in calcium and magnesium. Lime acts as a natural acid neutralizer for soil , which helps to reduce acidity and assist in returning the soil to a pH neutral status.

Do people garden organically?

The vast majority do not garden organically. In most of these gardens – no organic matter has been added. Thus, most of the beneficial microbes that make nutrients available to plants have been destroyed. In turn, these folks add all kinds of foreign things to the soil just to get it to produce crops – (lime being a favorite here).

Does everyone use lime in their soil?

Allow me to lay the ground work for the remainder of this post by saying that I live in an area where it seems everyone uses lime on their soil. Farmers here use it on their fields in great quantities and home gardeners use it on their gardens.

Is organic matter good for soil?

In spite of all the brainwashing that goes on by sellers and makers of synthetic amendments, the fact is: Organic matter is the answer to all your ph, soil building and conditioning problems. If your soil is rich in organic matter —- everything else will fall into place.

Can you add lime to soil?

I’d strongly recommend staying away from using lime. Adding “foreign stuff” to your soil is pretty much a waste of time, money, and effort. Why add things like lime and possibly disrupt the balance of nutrients already there waiting to grow your plants strong and healthy. Why take a chance on ruining your soil when you can just add organic matter and let nature solve all the problems.

Does organic matter change pH?

Not only will organic matter change the ph towards neutral, but over time it will add all nutrients needed to grow plants including nitrogen, phosphorous, potassium, calcium, magnesium, zinc, iron, sulfur, copper, manganese, boron, etc. If you like easy — (I do) — you can’t get much easier than that.

Is lime good for alkalinity?

The thought behind the use of lime (at least in this area) is: the soil is clay and/or acidic therefore it needs to be “sweetened” — which is another way of saying the ph needs to be raised. Some see it (falsely) as a panacea for raising the alkalinity of an acidic soil.

What is the purpose of pulverized limestone?

Applying pulverized limestone is the low cost way to supply calcium nutrients to the soil and to help adjust the soil pH in the same application. Each ton of New Enterprise calcium limestone adds approximately 610 pounds of calcium and 66 pounds of magnesium to the soil.

What is Pulverized Aglime?

New Enterprise pulverized aglime is available in bulk or by the bag to meet the needs of farmers and commercial applicators as well as homeowners. Pulverized limestone application helps maintain proper soil pH levels and replenishes vital calcium and magnesium nutrients to help maintain fertile soil conditions in plant root zones and ensure that your soil is most favorable for plant growth. Maintaining proper soil pH increases the effectiveness of high-cost fertilizers and herbicides and increases the effectiveness of other natural soil nutrients such as phosphorus, nitrogen, and manganese which are sensitive to soil pH.

How many pounds of limestone is in a dry bag?

Dry bagged – 50 pound bags of calcium and magnesium (dolomitic) limestone are available for smaller lawn and garden applications with the same quality guarantees.

Why use lime in agriculture?

The first obvious benefit to using agricultural lime is that it has been proven time and again to effectively balance out soil pH levels and improve plant health. Soil that has become to acidic as the result of frequent crop cycles or acid rain makes it difficult for nutrients to be absorbed through a plant’s root system or even for water to fully penetrate the earth.

Why is lime important to soil?

Lime is selected because it contains such a high amount of calcium, which works to neutralize the soil’s pH levels. In addition to this, agricultural lime is also able to increase the ability of vegetation to absorb essential nutrients from the ground.

What is the difference between dolomitic lime and calcium carbonate?

The primary difference between the two materials is that, in addition to containing calcium carbonate, dolomitic lime also contains a mixture of magnesium carbonate. Typically, the mineral is comprised of approximately 50% calcium carbonate and 40% magnesium carbonate with the remainder being other materials.

How is dolomitic lime made?

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.

What is lime used for?

For centuries, the natural stone product of agricultural lime has been used to improve growing conditions for farm fields, gardens and even residential lawns. While liming is extremely common in the agricultural sector, there are different options to consideration. One of the most common limes compared to aglime is dolomitic lime.

What is aglime made of?

Typically, aglime is spread in its pure, dry “ calcitic ” form, meaning that the product is comprised mainly of calcium carbonate. At the same time, you may also find some other variations of agricultural lime. Liquid lime, for example, is applied using a combination of approximately 50% dry aglime and 50% water.

Why is lime used in the wind?

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. It should also be noted that agricultural lime reacts more quickly with water. If your soil is particularly dry, it may take more time for you to achieve the desired results.

What is Ag Lime?

Ag lime, or agricultural lime, is a coarse limestone product best suited for agricultural applications. The name ag lime most often refers to a crushed limestone product that is used to improve acidic soil to a neutral pH.

Why use lime in soil?

The benefits of applying a lime soil amendment are a result of lime’s ability to correct soil acidity. Lime applications neutralize the acidity of the soil, allowing plants to absorb previously locked up nutrients. Consequently, a better soil environment is created, allowing plants to yield optimal results. Pelletized limestone, often referred …

What is pelletized limestone?

Pelletized limestone, often referred to as pelletized lime, is created when limestone rock is crushed into a powder and then granulated. The powdered lime is ground to a very fine consistency, allowing the product to dissolve quickly and start working fast. Equipment such as a disc pelletizer is used to form the powder into a granule, …

How is lime powder made?

Powdered (or ground) lime is created by crushing and grinding limestone rock to a powder. By changing to a powdered form, lime can break down quickly and begin working faster than options such as ag lime. When comparing pelletized lime vs. powdered lime, the major difference comes down to ease of handling.

What is the role of polymers in soil?

Polymers that hold nutrients in the soil’s root zones, delivering nutrients where they are needed.



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 lime…

Determining the need for agricultural lime

Where soils are acidic, lime can improve crop yield and the root system of plants and grass. It does this by making the soil more basic and thereby allowing the plants to absorb more nutrients from the soil. Lime is not a fertilizer itself, but can be used in combination with fertilizers.
Soils become acidic in a number of ways. Locations that have high rainfall levels become acidic through leaching. Land used for crop and livestock purposes loses minerals over time by crop removal and becomes acidic. The a…


The quality of agricultural limestone is determined by the chemical makeup of the limestone and how finely the stone is ground. To aid the farmer in determining the relative value of competing agricultural liming materials, the agricultural extension services of several universities use two rating systems. Calcium Carbonate Equivalent (CCE) and the Effective Calcium Carbonate Equivalent (ECCE) give a numeric value to the effectiveness of different liming materials.

Brazil’s case

Brazil’s vast inland cerrado region was regarded as unfit for farming before the 1960s because the soil was too acidic and poor in nutrients, according to Nobel Peace Prize winner Norman Borlaug, an American plant scientist referred to as the father of the Green Revolution. However, from the 1960s, vast quantities of lime (pulverised chalk or limestone) were poured on the soil to reduce acidity. The effort went on and in the late 1990s between 14 million and 16 million tonnes of lime were being spread on Brazilian fields each year. The quantity rose to 25 mill…

Effect on prehistoric mobility studies

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 c…
