Some effects of agricultural lime on soil are:
- it increases the pH of acidic soil, reducing soil acidity and increasing alkalinity [1]
- it provides a source of calcium for plants
- it improves water penetration for acidic soils
- it improves the uptake of major plant nutrients ( nitrogen, phosphorus, and potassium) of plants growing on acid soils. [2]
What does lime application to soil really do?
- The pH levels increase in any soil with high acidic levels.
- Plants will be able to receive the required magnesium and calcium they need to stay healthy.
- Water can now penetrate into soils with high acidic levels and hydrate them.
- Lime enables plants that are growing on acidic soils to absorb more nutrients than usual.
Does lime lower pH in soil?
Lime is a soil amendment made from ground limestone rock, which naturally contains calcium carbonate and magnesium carbonate. When lime is added to soil, these compounds work to increase the soil's pH, making soil less acidic and more alkaline. About Us.
Does my soil need lime?
The amount of lime your soil needs depends on the initial pH and the consistency of the soil. Without a good soil test, judging the amount of lime is a process of trial and error. A home pH test kit can tell you the acidity of the soil, but it doesn’t take the type of soil into consideration.
Is Lyme good for soil?
Lime ensures a healthier base for your plants to grow. It improves the structure of the soil. If your soil has lime, the plants are going to be able to access nutrients and minerals much easier. Adding lime in the soil mix is also very good for plants that like good drainage as well as plants that like moisture-retentive soil.
How do you know if you need to add lime to your soil?
Signs You Need to Apply LimeYou have sandy or clay soil. ... Weeds or moss have grown in your yard.The fertilizer you're using doesn't appear to be working. ... Your area experiences a lot of rainfall, especially acid rain.The grass is yellowing.More items...•
Can you add too much lime to soil?
Using too much lime on your lawn will remove the acidity from the soil, but it will also make it too alkaline for your grass to thrive. This will cause yellowing grass that is also not able to absorb vital moisture and nutrients from the soil around it.
Why do gardeners add lime to soil?
Liming garden soil reduces the acidity of the soil by increasing the pH level. Plants can't get the nutrients they need from soil that is too acid, and some materials such as aluminium can be at toxic levels in very acid soils.
How often should lime be applied to soil?
every three to five yearsLime shouldn't be applied to grass and yards that are wilted or covered in frost. Since it can take two years for lime to move 2 inches into your soil, avoid over liming by applying lime only every three to five years.
Which plants do not like lime?
Any plants considered “acid-loving” plants shouldn't be given extra lime. This includes blueberries as well as ornamental shrubs such as azaleas, rhododendrons and hollies.
What are the disadvantages of liming?
Nonetheless, lime treatment has a number of inherent disadvantages, such as carbonation, sulfate attack and environment impact. Magnesium oxide/hydroxide are thus proposed as a suitable alternative stabilizer to overcome at least some of the disadvantages of using lime in soil stabilization.

Why does lime help plants?
They develop symptoms of nutrient deficiency, such as pale leaves and stunted growth. Using lime for acidic soil raises the pH so that plant roots can absorb the necessary nutrients from the soil.
How long does it take for lime to dissolve in soil?
You’ll begin to see a measurable difference in the soil pH about four weeks after adding lime, but it can take six to twelve months for the lime to dissolve completely. You won’t see the full effect of adding lime to the soil until it is completely dissolved and incorporated into the soil. For most gardeners, fall is a good time to add lime.
How to know how much lime to use in soil?
The amount of lime your soil needs depends on the initial pH and the consistency of the soil. Without a good soil test, judging the amount of lime is a process of trial and error. A home pH test kit can tell you the acidity of the soil, but it doesn’t take the type of soil into consideration. The results of a soil analysis performed by a professional soil testing laboratory includes specific recommendations tailored to meet your soil’s needs.
How to determine if lime is needed?
The best way to determine what is actually needed or not needed in terms of liming is to use a detailed soil analysis. The soil analysis should include measurement of calcium and magnesium and the percentage saturation of each in the soil. Growers cannot determine whether lime is required simply by measuring the pH of the soil. The soil testing methods should always include checking for both calcium and magnesium levels to determine if there is too little, too much or if the proper amount is already there. An overall picture of what over-liming actually does to a soil can be seen by taking a soil sample prior to the use of the lime and following up each year for the next three years.
What is the most common source of calcium in soil?
Some growers might think that just as long as there is not too much limestone applied, there is no problem. High calcium limestone (calcium carbonate) and gypsum (calcium sulfate) are generally considered the most common sources of calcium. But the problem can be caused by other materials, as well as poultry manure, especially from laying hen operations (where calcium is supplemented to strengthen the egg shells), can be a significant source of additional calcium. Certain types of wood ashes that are applied at high tonnage rates, and some sources of irrigation water, can also contribute substantially to the levels of calcium in the soil.
How does lime affect water?
Lime’s Effect on Water Use. Use of calcium also increases the pore space in the soil. This is a desirable result until pore space reaches 50 percent of the total soil volume. But when too much calcium is applied by over-liming, so much pore space can result that the soil dries out much easier than before. So you can lose efficiency of water use, ...
What happens when the pH of the soil is too high?
Just by increasing soil pH, phosphate may be released and increased in the soil. But if the pH goes too high, phosphates can also be tied up. Using more than enough lime can cause the pH to increase so much that this happens. In addition, pH can tie up other elements such as boron, iron, manganese, copper and zinc, as it increases.
Why is my chicken's egg shell a problem?
But the problem can be caused by other materials, as well as poultry manure, especially from laying hen operations (where calcium is supplemented to strengthen the egg shells), can be a significant source of additional calcium.

Why do plants lose their green color?
When your plants' leaves don't produce enough chlorophyll, they may develop chlorosis, which can cause your your plants to lose their rich green coloring. Chlorosis inhibits a plant's ability to produce carbohydrates through photosynthesis and may die if left untreated.
Is lime good for landscaping?
There are different kinds of lime, not all of which are preferred for landscaping purposes. As Charlotte Glen of the North Carolina State extension notes, agricultural or "garden" lime is made from calcium carbonate, and dolomitic lime from dolomite; both are suitable for landscaping use. But Glen warns that slaked lime and quick lime "are not recommended for lawns and gardens." The same source observes that both the type deriving from calcium carbonate and the kind that comes from dolomite furnish your garden with calcium, while the latter is a source of magnesium, as well. So while lime is not really a "fertilizer," it can, nevertheless, supply your garden with important minerals.
How to tell if grass is acidic?
Other warning signs include increases in common lawn weeds, diseases and insect pests. Many weeds prefer acidic soil, and low soil pH can inhibit the effectiveness of some herbicides and insecticides. 2 When soil is overly acidic, you'll also notice that grasses don't respond to quality lawn fertilizers with the healthy, ...
What happens when soil is too acidic?
When soil becomes too acidic, lawn grasses struggle and plants that flourish in acidic soil take their place. For example, the presence of lawn moss signals your soil pH has become too low for strong, healthy grass growth. Other warning signs include increases in common lawn weeds, diseases and insect pests. Many weeds prefer acidic soil, and low soil pH can inhibit the effectiveness of some herbicides and insecticides. 2 When soil is overly acidic, you'll also notice that grasses don't respond to quality lawn fertilizers with the healthy, lush growth you normally expect.
Why does soil pH change?
Soil pH changes for many reasons, including the lime or other products you add. In areas with heavy rainfall, calcium naturally leaches away as rainwater passes through soil. The loss of calcium means soil pH drops and soils become acidic over time. In these regions, lime is usually a necessity for healthy lawns. In areas with very little rainfall, calcium doesn't leach away, and lawns can become too alkaline. Proper lawn maintenance also naturally lowers soil pH over time. Regular fertilization, proper irrigation and increased activity of beneficial soil microorganisms all contribute to gradual, normal drops in soil pH. 2
What is lime made of?
Lime is a soil amendment made from ground limestone rock, which naturally contains calcium carbonate and magnesium carbonate. When lime is added to soil, these compounds work to increase the soil's pH, making soil less acidic and more alkaline. Even though lime includes calcium and magnesium, which are essential nutrients for healthy plant growth, it's not a substitute for fertilizer. Lime's primary role is to alter soil pH and offset soil acidity, which can improve the availability of plant nutrients.
Why does my lawn need lime?
Soil pH changes for many reasons, including the lime or other products you add. In areas with heavy rainfall, calcium naturally leaches away as rainwater passes through soil. The loss of calcium means soil pH drops and soils become acidic over time. In these regions, lime is usually a necessity for healthy lawns.

By liming your lawn when it's needed, you help ensure your grass gets the nutrients and advantages it needs for lush, healthy, beautiful growth.
How to tell if your lawn is acidic?
Plants' ability to absorb absorb nitrogen is especially affected by soil pH; this is why lawns are especially sensitive. Nitrogen is the soil nutrient most responsible for green foliage, and turf lawns are nothing but green foliage. A lawn struggling to grow in acidic soil may show the following signs: 1 Weak growth 2 The presence of lawn moss 3 Disease 4 Insect infestation 5 Weeds 6 Failure to respond after treatment with fertilizer 7 Washed-out color
What type of lime is used for lawns?
There are several types of agricultural lime used as a soil amendment to correct pH, but the form normally applied to lawns is pulverized, powdered limestone or chalk. Lime with a high calcium content is referred to as calcitic lime and it has the benefit of adding calcium to the soil. Some limestone contains a significant amount of magnesium and is referred to as dolomitic lime. Dolomitic lime adds magnesium to the soil and may be recommended if soil tests indicate a magnesium deficiency. The best type of lime to apply depends on the results of your soil test.
Why is my lawn so sensitive to nitrogen?
Nitrogen absorption of plants is especially affected by soil pH, and this is why lawns are especially sensitive. Nitrogen is the soil nutrient most responsible for green foliage, and turf lawns are nothing but green foliage. A lawn struggling to grow in acidic soil may show the following signs:
How to tell if your lawn needs acid soil?
While acid soil tends to make itself known by lawn grasses that fail to thrive or problems with moss growth, the only way to verify that acid soil is an issue is with a soil pH test. You can buy DIY soil test kits at garden centers and hardware stores, but these tests are often unreliable and the information may not tell you how much lime your lawn needs. For the same amount of money (and a little more time—perhaps two to three weeks), you can have your soil tested at a local extension service. Most university extensions test soil for about $10 to $20 and the report you receive usually offers a much more detailed analysis of your soil's composition and pH level.
Why is pH 4.5 bad?
A lower pH level, indicative of very acidic soil, is problematic because it prevents plants from absorbing nutrients. In a soil with a very acidic pH of 4.5, for example, it is estimated that about 70 percent of applied fertilizer is wasted because plants can't make use of it. 1 Agricultural lime for lawns has alkaline properties ...

Can you use dolomitic lime on lawn?
Lime can be messy to apply if you buy the cheap stuff. Pay a little more for pelletized dolomitic lime. It will be easier to apply with your broadcast spreader, and will add calcium and magnesium to your lawn while raising your soil’s pH.
Why Add Lime?
Warm-season grasses, on the other hand, prefer a slightly lower, or more acidic, pH. When the soil pH becomes too acidic, though, certain nutrients needed for proper growth (such as nitrogen, phosphorus, potassium, and calcium) become unavailable to the lawn, so the grass is unable to grow properly. Lime (sometimes called garden lime) or limestone can be applied to the soil to help increase the soil pH and make those nutrients more available.
What is the best lime for soil?
Calcitic lime is the preferred type, thanks to the added plant benefits provided by the calcium.
