What is lime used for in agriculture?

Agricultural lime is the most effective soil amendment for raising pH levels in order to improve crop health and production. Agricultural lime is a soil amendment product used to condition soil by raising pH levels. It is made from crushed limestone that contains natural nutrients to promote healthy plant growth.


What is the use of agricultural lime?

Agricultural lime has been used by farmers for years as a soil improver. It’s also a natural, low-cost way to enhance the effects of regular chemical-based fertilizers. By reducing soil acidity, aglime makes a huge difference to the productivity potential of both arable and grassland farming.

What is agricultural lime made of?

Agricultural lime, also sold as garden lime, is made from calcium carbonate. This type of limestone can be found in our area and is mined in Pender County at the Shelter Creek Quarry near Maple Hill. Dolomitic lime is made from dolomite, a type of rock very similar to limestone except it also contains magnesium.

What is the difference between hydrated lime and agricultural lime?

Slaked lime (also called hydrated lime or builder’s lime) is calcium hydroxide (Ca(OH)2) and has a higher neutralising value than agricultural lime but is more expensive and not usually applied to pastures.

Is agricultural lime harmful to humans?

Non-Caustic Lime While broadly speaking, non-caustic limes, or “ag limes” are considered non-toxic for people, pets and the wildlife passing through, non-toxic does equate to a substance being 100% safe. Non-toxic literally refers to a material as not causing death or serious illness.

Is agricultural lime a fertilizer?

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.

How do you apply agricultural lime to soil?

Working lime into the soil in the fall gives it several months to dissolve before spring planting. To add lime to the soil, first prepare the bed by tilling or digging to a depth of 8 to 12 inches (20-30 cm.). Spread the lime evenly over the soil, and then rake it in to a depth of 2 inches (5 cm.).

What type of lime is best for gardens?

Limestone alters the pH of the soil and provides nutrients to plant life. Ground limestone, either calcitic or dolomitic, is the most used, most abundant, and generally least expensive form of lime.

Is agricultural lime organic?

Lime is a purely natural (organic) fertilizer. This fertilizer is added to the soil to alter soil PH so as to reduce soil acidity. Lime fertilizers can facilitate better nutrient uptake and it’s probably the most economical way to provide additions of calcium and magnesium.

Is crushed limestone the same as ag 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).

Acidic Soil Problems

One of the most important conditions for ensuring agricultural crops will grow is the condition of the soil, including the pH balance. When soil becomes too acidic, it can make it very difficult to maximize the yield of agricultural crops.

What Is Agricultural Lime?

In order to counter the high acidity of the soil, certain soil amendments can be added to raise the pH levels and neutralize the acidic soil. Agricultural lime is the most effective soil amendment for raising pH levels in order to improve crop health and production.

Types of Lime for Agricultural Crops

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

Reducing Acidity Levels in Soil

Soil naturally contains countless minerals and nutrients that each serve a purpose in helping crops grow healthily. When the mineral content becomes unbalanced, the soil can become too alkalized or too acidic depending on the levels of the different types of minerals.

How Lime Helps Crops Grow

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 Crops React to Lime

Different types of plants are more resistant to acidic soil than others. Certain types of plants can withstand the toxicity of acidic soil, while others will be much more susceptible and will not be able to withstand the toxicity. It’s important to understand each crop’s specific acidic tolerance before applying a lime solution.

Applying Lime to Agricultural Crops

Once the soil has been tested throughout the field, you can then determine the appropriate amount of lime to use. Certain sections of the soil may be more acidic than others. In this case, a suitable lime application plan must be created in order to avoid over- or undersupplying lime across the field.

What is agricultural lime?

Aglime is essentially just limestone or dolomite that has been ground, washed and screened for use as a soil treatment. The chemical makeup of the aglime makes it possible for essential minerals like calcium and magnesium to be reintroduced into the ground and for pH levels to be restored to neutral.

What types of agricultural lime are available?

If you’ve decided to use aglime to improve the soil conditions throughout your property, you’ve probably noticed that you have several different options. You’ll need to be aware of the specifications of each to ensure that you select the right material for your needs.

How should agricultural lime be applied?

In order to get the most benefit from your aglime, you’ll need to keep a few important items in mind throughout the application process: Volume Required – Different plants thrive in soils with varying pH levels.

How quickly does agricultural lime work?

Most users are anxious to see a positive improvement in the pH of their soil, but it’s important to keep in mind that several factors will come into play as the aglime begins to do its work. The first thing to note is that water is required for lime to react with the soil.

How frequently should agricultural lime be applied?

In addition to measuring pH levels which will reveal the active acidity of the soil, it’s also important to consider the cation exchange capacity (CEC) of the earth. The CEC measures both the active and reserve acidity of the soil.

Can agricultural lime be used with other chemicals?

Depending on your needs, it may be important for you to understand how aglime works with:

Where can I get the best prices on agricultural lime?

When purchasing agricultural lime, you should understand that the “best” price isn’t necessarily the same thing as the “cheapest” product.


Ag Lime, or agricultural lime, is a soil conditioner made from crushed limestone or dolomitic limestone. Ag lime works by dissolving and releasing a base that lowers the acidity of the soil.

Benefits Of Agriculture Lime

Liming soils to prevent excess soil acidity (where it limits yields) is a best management practice. The proper use of lime is one of the most crucial components to a successful crop management program because excess acidity can severely limit both short-term and long-term soil productivity.

When to Use Aglime or Dolomite

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.

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.

Dolomitic Lime

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.

Choosing the Right Liming Agent

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.

The Best Place to Purchase Liming Materials

Once you’ve decided which type of lime is right for your needs, you’ll want to make sure that you’re buying your materials from a reliable supplier. Braen is one the largest suppliers of aglime throughout NJ and NY. We sell only the highest quality liming agents at competitive wholesale pricing.

The Basics of Pelletized Lime

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 Lime vs. 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.

Pelletized Lime vs. Powdered Lime

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.

Pelletized Lime vs. Imposters

The following chart illustrates the benefits and effectiveness of pelletized lime in comparison to other lime products:

Double Check

Most plants grow best in soil that has a pH level between 5.5 and 6.5, although a few plants prefer a pH around 5. All pH levels lower than 5.5 are so acidic the plants have difficulty absorbing the nutrients in the soil. Adding agricultural lime to acidic soil raises the pH level to make the soil more conducive for gardening.

Stone Types

Agricultural lime may also be labeled as garden lime and is mainly calcium carbonate. In low pH soil, it adds calcium to the soil. Dolomitic lime is made through the same process as agricultural lime, but uses a stone called dolomite rather than limestone. In addition to calcium, dolomitic lime also provides magnesium.

Working Through

After it is applied, agricultural lime is stable in the soil and does not move. It only affects pH levels in the soil it contacts. No matter which type of agricultural lime is used, it should be applied evenly and then worked into the soil.

Other Benefits

Proper use of agricultural lime in acidic soil can improve the soil in other ways. In areas that leach potassium, adding agricultural lime increases the soil’s ability to retain potassium, reducing the need for fertilizer applications. Aluminum in the soil combines with phosphorus in fertilizer and causes it to become insoluble.

What is Barn Lime?

Barn lime is crushed up limestone – also known as Calcium Carbonate. It’s used to prevent the smell of ammonia build-up and odors in barns and stalls. Ammonia comes from the urea in livestock waste when it’s left sitting and not cleaned up.

When to Use Barn Lime

It’s important to keep your stalls clean in the first place. While barn lime can help with ammonia odors, it’s best to clean your stalls on a regular basis. Damp, odorous conditions are an invitation for flies and other pests. Clearing out animal droppings, manure, wet bedding, and damp hay can help with fly control on the farm.
