What is used to treat acidic soil?
Treatments for Soil Acidity – Soil acidity can be ameliorated and the pH of the soil increased by the addition of lime/limestone (calcium carbonate) and similar compounds that have been ground fine for use. Types of lime-like amendments include:
Dolomitic limestone Quicklime Hydrated lime Marl Chalk Oystershell Wood ashes Fluid lime
Each lime-like amendment has its benefits and drawbacks, such as effectiveness, price, and purity. Lime is most effective at neutralizing acidity when it is incorporated/tilled into the soil to the full depth of the plow layer or root zone. Surface application of lime to a field. Plants should be irrigated after lime application to ensure the foliage is free of the amendment. Photo credit: Dwight Sipler Flickr CC BY 2.0
Do farmers add calcium carbonate to treat acidic soil?
Calcium carbonate, the chief component of limestone, is a widely used amendment to neutralize soil acidity and to supply calcium (Ca) for plant nutrition. The term “lime” can refer to several products, but for agricultural use it generally refers to ground limestone.
- Production Limestone is a common sedimentary rock found in widespread geologic deposits.
- It has been used throughout much of recorded history as a building material, a cementing agent, and in agriculture to improve acid soils.
- An agricultural liming material (ag lime) is broadly defined as any substance containing Ca or magnesium ( Mg ) and capable of neutralizing acidity.
Many materials can be classified as ag lime. Ag lime is extracted from quarries or mines and usually requires mechanical crushing. The fineness of the ag lime is important in determining how quickly it reacts with soil acidity. Limestone of a smaller particle size reacts quickly because of the larger surface area exposed to chemical reaction.
- Larger particles react slower, but provide a sustained, longer-term source of acid neutralization.
- A measurement of particle size typically appears on the product label.
- Other materials in the ag lime, such as clay, will reduce its purity and diminish the acid-neutralizing capacity.
- Ag lime effectiveness is rated based on its comparison with pure calcium carbonate (CaCO₃), a value that is expressed as the percent calcium carbonate equivalent (CCE).
Ag lime is more soluble in acid soils than in neutral or alkaline soils. The presence of CaCO₃ in soil is detected by the effervescence or “fizz” when a drop of strong acid is applied. Agricultural use The primary use of ag lime is to raise the pH of acid soils and reduce the concentration of aluminum (Al) in soil solution.
- Poor crop growth in acid soils largely results from too much soluble Al, which is toxic to the root system of many plants.
- Lime will reduce soluble Al through two reactions: CaCO₃ + H₂OICa²⁺ + 2OH⁻ + CO₂ and Al₃ + + 3OH – IAl(OH)₃,
- Additions of ag lime also supply valuable Ca (and possibly Mg ) for plant nutrition.
Some secondary benefits of neutralizing soil acidity with ag lime include:
Increased phosphorus (P) availability; Improved nitrogen (N) fixation by legumes; Enhanced N mineralization and nitrification; and Better water use, nutrient recovery and plant performance with a healthier root system.
Management practices Lab testers can easily determine the quantity of ag lime needed to bring a soil to a desirable pH range. Most commonly, farmers spread the lime uniformly on the soil and then mix it through the root zone. Neutralizing soil acidity is not a one-time process, however, and must be repeated periodically depending on soil and environmental conditions.
- Typical application rates are measured in tons per acre.
- Non-agricultural uses Limestone is one of the most widely utilized of all earth materials.
- In addition to its use in building and construction, limestone’s diverse applications include air pollution control, treatment systems for drinking water and wastewater, soil stabilization, medicines, antacids, and cosmetics.

What is added to the acidic soil to reduce acidity?
Whenever soil is found to be acidic, calcium hydroxide is used to neutralise its effect. This is because calcium hydroxide is alkaline in nature. Calcium hydroxide is commonly known as hydrated lime or slaked lime.
Which compound is used by farmers to reduce soil acidity?
The most effective treatment for soil acidity is fertilizing the ground using limestone. Liming materials used in agriculture such as calcium carbonate, dolomite and magnesium oxide correct soil acidity by adding calcium and lime into the environment as a powder.
What helps reduce acidity in soil?
Increasing the Soil pH – To make soils less acidic, the common practice is to apply a material that contains some form of lime. Ground agricultural limestone is most frequently used. The finer the limestone particles, the more rapidly it becomes effective.
Different soils will require a different amount of lime to adjust the soil pH value. The texture of the soil, organic matter content and the plants to be grown are all factors to consider in adjusting the pH value. For example, soils low in clay require less lime than soils high in clay to make the same pH change.
Selecting a Liming Material : Homeowners can choose from four types of ground limestone products: pulverized, granular, pelletized and hydrated. Pulverized lime is finely ground. Granular and pelletized lime are less likely to clog when spread with a fertilizer spreader over turf areas.
The finer the grind of the limestone the faster it will change the soil pH value. Hydrated lime should be used with caution since it has a greater ability to neutralize soil acidity than regular limestone. Time of Application & Lime Placement : Lime needs should be determined by a soil test. For more information on soil testing, refer to HGIC 1652, Soil Testing,
Soil samples should be taken in the fall for the succeeding year’s garden. If test results indicate a need for limestone, it can be applied in the fall or winter months. Generally, for best results, limestone should be applied two to three months prior to planting to allow time for it to neutralize the acidity.
The most important factor determining the effectiveness of lime is placement. Maximum contact of lime with the soil is essential. Most liming materials are only slightly soluble in water, so incorporation in the soil is a must for lime reaction. Even when properly mixed with the soil, lime will have little effect on pH if the soil is dry.
Moisture is essential for the lime-soil reaction to occur. In the case of lawns, it can only be surface applied and watered into the soil. Wood Ashes : Wood ashes can be used to raise the soil pH. They contain fairly high amounts of potassium & calcium, and small amounts of phosphate, boron and other elements.
They are not as effective as limestone but with repeated use, they can drastically raise the pH value of a soil, especially if the soil is sandy in texture. Ashes should not come in contact with germinating seedlings or plant roots as they may cause damage. Spread a thin layer during the winter and incorporate into the soil in the spring.
Check the soil pH annually especially if you use wood ashes. Avoid using large amounts of wood ashes because excessively high pH values and subsequent nutrient deficiencies may result. Coal ashes do not have any lime value and may actually be acidic dependent on the source.
How do you remove acidity from soil?
Reducing Soil pH High soil pH can lead to a yellowing of tissue between leaf veins. Sherry Combs, formerly of the UW-Madison Soil and Plant Analysis Lab Revised: 10/27/2007 Item number: XHT1151 Is your soil pH too high? Probably not, although the popular press urges most gardeners to question whether their garden soil pH is ‘right’.
- Only a soil test for pH can indicate whether the pH is ‘right’, and ‘right ‘ really depends on the plant you want to grow and the natural pH of your soil.
- Turf, vegetables, annual ornamentals and most perennial ornamentals are very tolerant of a wide range of soil pH levels, and acidifying soil is generally not necessary or recommended.
Blueberries, rhododendrons and azaleas however, are quite intolerant of alkaline conditions and the soil pH must be maintained at 5.5 or less in order to grow them successfully. To determine current soil pH, start with a soil test. For soils having a pH of less than 7.5, you should be able to add a soil amendment (e.g., some form of sulfur) and successfully lower pH, if recommended.
- If soils have a pH above 7.5, adding a soil amendment will probably not reduce pH much because of the ‘free’ calcium carbonate or marl present in these soils.
- This is an unfortunate characteristic of soils in some parts of Wisconsin.
- In these soils, consider growing plant species more tolerant of high pH conditions.
Soil pH can be reduced most effectively by adding elemental sulfur, aluminum sulfate or sulfuric acid. The choice of which material to use depends on how fast you hope the pH will change and the type/size of plant experiencing the deficiency. Sulfuric acid (commonly available as battery acid) is fast acting, but is very dangerous, and its use by home gardeners is not recommended.
- Green industry professionals however, occasionally use sulfuric acid to reduce soil pH around large, established specimen trees.
- Aluminum sulfate and elemental sulfur can be safely used by homeowners.
- Aluminum sulfate is faster acting than elemental sulfur because it is very soluble.
- The advantage of elemental sulfur is that it is more economical, particularly if a large area is to be treated.
In general, it is best to reduce soil pH before planting sensitive landscape ornamentals, rather than attempting to reduce soil pH after plants have become established. Use about 4 to 6 lb. of aluminum sulfate per plant for most medium- and fine-textured Wisconsin soils in order to decrease soil pH by about one unit.
- If elemental sulfur is applied, decrease the total recommended application by one-sixth.
- One pound of aluminum sulfate or elemental sulfur is equal to about 2 cups.
- As an example, suppose your initial soil pH is 7.4 and you want to plant blueberries which require a pH of no higher than 5.5.
- You should apply about 8 to 12 lb.
(16 to 24 cups) aluminum sulfate, or 1 1/3 to 2 lb. (2 3/4 to 4 cups) elemental sulfur per plant. Be sure to delay planting for about one month after application to avoid root burn. If plants are already established, use a top-dress application limited to about 1 lb.
- 2 cups) aluminum sulfate or 1/6 lb.
- 1/3 cup) elemental sulfur per typical landscape plant.
- Lightly incorporate the aluminum sulfate or elemental sulfur into the soil, or water-in well.
- Repeat applications monthly until the total recommended amount of aluminum sulfate or elemental sulfur has been added.
Because lowering soil pH is a very slow process, have the soil pH checked about three months after each application to determine if additional applications will be needed. Several applications may be needed on some soils before the soil pH shows any significant change.
- Applying certain fertilizers, such as ammonium-containing nitrogen fertilizers like ammonium sulfate, urea or ammonium sulfate, can help maintain acid soil conditions, but these fertilizers will probably not be effective in significantly reducing soil pH.
- The ammonium in these products reacts in the soil to help maintain the lowered pH.
Keep in mind however, that many fertilizer products such as potassium sulfate and gypsum will not effectively reduce soil pH. Peat moss and certain other organic materials such as pine needles are a good source of organic carbon and can be used to help reduce soil pH.
However these organic materials are very slow acting and may not be effective for causing large soil pH changes. Try adding a one to two inch layer of these organic materials and incorporate them into the top six to 12 inches of soil before planting. Afterwards, check the pH. Addition of aluminum sulfate will probably still be needed to ensure that the soil pH is reduced enough for successful gardening.

Why do farmers add lime to acidic soils?
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. 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 farmers use calcium carbonate?
Calcium carbonate and dolomite are suited to a wide variety of agricultural applications, including pH control, fertilizer conditioners and fillers, and animal feed formulations. LLandscape and recreation uses include decorative stone for landscaping, golf course applications, and athletic-field line marking.

Agricultural requirements for crop production target specific pH ranges for soil to optimize production, reduce blossom end rot on tomatoes, and facilitate development of mushroom spawns. Soil-application products can be designed for field spreading or can be pulverized for drip irrigation use.
Calcium carbonate also is important in animal nutrition. Calcium supplements for cattle and other livestock play a key role in bone growth and strength as well as in general animal health. Poultry require grit in the gizzard to assist with digestion and strengthen shells for proper egg production. Calcium carbonate is also used in animal nutritional supplements.
Chemical purity, brightness, and consistency play a major role in the end value for the application. Tan Ky Mineral Processing JSC is well positioned to supply you with our standard products or work with you to develop new products tailored for your applications. Calcium carbonate is the main component of limestone. This is a widely used mineral to offset the soil acidity and to provide the calcium to the plants for their nutrition. Calcium Carbonate is widely used in agricultural industries.
Why do farmers add calcium oxide to soil?
Soil liming or whitewash prevents the migration of phytotoxic elements such as magnesium and aluminium, which reduce growth and negatively affect the development of crops. Crops need a certain pH for optimum growth. Rain intensifies field exploitation, causing acidification in the soil.
Prepare the soil for the crop to absorb the nutrients in excellent conditions.
Remove the phytotoxicity of aluminium, a basic element of silicates, through the transformation of other non-toxic ionic species for crops.
Reduces the solubility of heavy metals, and thus, its bioavailability for crops.
Apart from pH, with the addition of Calcinor’s products:
The calcium state of the soil is regulated. Calcium soil state indicates its suitability for agricultural use. To regulate this calcium state products with calcium and/or magnesium are used, for example limestone, dolomite or corresponding oxides.
Calcium products keep the structure of agricultural soil stable. The stability of this structure is essential to correctly develop the main functions for a correct growth of the crops.
The magnesium contained in our products is a chlorophyll component, a necessary requisite for the development of photosynthesis in plants.
Products such as oxide are absorbed and quickly correct the pH of soils, whereas carbonate has an absorption and regulation effect in the medium term. The wide range of grading and offer of regulation products, Calcinor makes it possible to provide the best solution for each soil and agricultural plan.
How do you treat acidic and alkaline soil?
Organic Matter or Compost is usually the most effective treatment. This will help acidify the Alkaline Soil lowering the pH levels by enhancing the dissolved Calcium in the water. The organic matter is being decomposed by beneficial microbes this releases CO 2 which then forms Carbon Acid.
What substance Cannot be added to soil to reduce its acidity?
(D) Ammonium chloride is acidic, so it cannot be used as it will increase acidity.
