approach is to lime the field ade-quately before getting into conser-vation tillage. Lime to the pH sug-gested for the most acid-sensitive crop in the rotation. Using a coarser grade of lime will provide some larger particles that will continue reacting with soil acids after the fine lime has dissolved. Check the pH of the top 2 inches of soil every
What is the difference between agricultural lime and regular 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.
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.).
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.
What kind of lime is used for agriculture?
Lime Form. The most commonly used liming material in North Carolina is finely ground dolomitic rock, but calcitic lime is also widely used. Additional liming materials include burnt lime or hydrated lime, pelleted lime, liquid lime, wood ash, and industrial slags.
Is agricultural lime safe for plants?
The addition of lime to garden soil can increase the alkalinity of acidic soil and add plant nutrients and minerals, creating a healthy lawn and a healthier base for plants to grow. Agricultural lime and dolomitic lime are two types of lime commonly used in lawns and gardens.
Which plants do not like lime?

Can you add too much lime to soil?
Addition of excess lime can make soil so alkaline that plants cannot take up nutrients even when these nutrients are present in the soil. The soil may also accumulate excess salts. These conditions stunt plants and cause yellowing of leaves. Often, while leaves turn yellow, the leaf veins remain green.
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.
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.
Quality
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.
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.

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.
Background
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.
What Is Limestone Used For?
If you haven’t used limestone before you may be wondering “what is limestone used for?” Agricultural Lime (Ag Lime) helps take care of a particular challenge faced by farmers. As you grow over the years, in most cases your soil will become more acidic.
Common Uses of Limestone
Ag Lime is a soil conditioner. It is made from crushed limestone that is sometimes deployed in pellet form. The pellets allow it to be spread evenly with minimal dust, yet they break down into a finely pulverized texture when it is activated with water. Once activated, Ag Lime dissolves and releases a base into a soil, thereby lowering its acidity.

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.
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:
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.
Overview
