quicklime, which is an alkali, is placed on the soil to neutralise acid soil and so raise its pH.
The soil becomes too acid due to the bacteria which help plants and animals decompose.
Why do we need to neutralise soil?
- Some plants grow better in less acid soils
- Bacteria, which cause plants to decompose and so fertilize the soil, grow better in less acid soils.

How can slaked lime be used by farmers and environmentalists?
Farmers use slaked lime as a soil amendment to raise pH levels and reduce acidity in the soil, improving nutrient availability for plant growth. Environmentalists use slaked lime to treat acidic mine drainage and neutralize soil pH in areas affected by acid rain, helping to restore damaged ecosystems and improve water quality.
How does slaked lime help in the treatment of acidic soil?
Slaked lime, also known as calcium hydroxide, helps neutralize acidity in soil by increasing the soil's pH level. It reacts with acidic compounds in the soil to form water and a neutralized salt. This process helps improve soil structure and makes essential nutrients more available to plants.
What do farmers put on acidic soil?
Farmers can add lime to acidic soil to help raise its pH level and make it more suitable for growing crops. Lime helps to neutralize the acidity in the soil, making it easier for plants to absorb essential nutrients. It's important to test the soil first to determine the amount of lime needed for effective neutralization.
What do farmers spread onto the acidic soil?
Farmers can spread lime on acidic soil to raise the pH level and make it more suitable for planting crops. Lime helps to neutralize the acidity in the soil, providing a better environment for plant growth.
What do farmers and gardeners add to their soil if it is acidic?
Farmers and gardeners add limestone, dolomite, or wood ash to acidic soil to raise the pH level. This process helps neutralize the acidity and make the soil more suitable for plant growth.
Why farmers add slaked lime to acidic soils?
Calcium Hydroxide (or Slaked Lime) is a strong base (as are all metal hydroxides, oxides, and carbonates) A Base is a substance with a pH of 8 or more. When an acid and a base react, the result is that a salt and water is formed. This also has the effect of neutralising a substance (giving it a pH of 7 or closer to 7) So slaked lime is added in order to reduce the acidity of the soil
How can slaked lime be used by farmers and environmentalists?
Farmers use slaked lime as a soil amendment to raise pH levels and reduce acidity in the soil, improving nutrient availability for plant growth. Environmentalists use slaked lime to treat acidic mine drainage and neutralize soil pH in areas affected by acid rain, helping to restore damaged ecosystems and improve water quality.
Why do farmers sometimes add slaked lime to acidic soil?
Farmers add slaked lime to acidic soil to raise the pH level, making the soil less acidic and more suitable for optimal plant growth. This helps improve nutrient availability to plants, enhances soil structure, and fosters beneficial microbial activity.
Why must farmers be careful not to add too much slaked lime to soil?
Excess slaked lime can increase soil pH to levels that are harmful to plant growth, leading to nutrient deficiencies and reduced availability of essential nutrients. It can also release toxic levels of aluminum or manganese into the soil, further damaging plant health. Overuse of slaked lime can disrupt the balance of beneficial microorganisms in the soil, affecting overall soil health and fertility.
What do farmers use limestone for?
Farmers use limestone to improve soil pH levels in their fields. Limestone is a natural way to reduce soil acidity and enhance nutrient availability for plants. It also helps to improve soil structure and boost crop productivity.
What substance is added to acidic soil?
Adding lime to acidic soil can help raise pH levels by neutralizing the acidity. Lime is typically applied in the form of ground limestone or dolomite, and helps to improve soil structure and nutrient availability for plants.
What are the differences between slaked lime and quicklime, and how do they each contribute to various applications in construction and agriculture?
Slaked lime is calcium hydroxide, produced by adding water to quicklime (calcium oxide). Quicklime is more reactive and used for faster reactions, while slaked lime is milder and easier to handle. In construction, quicklime is used for mortar and plaster, while slaked lime is used for soil stabilization. In agriculture, quicklime is used for pH adjustment and disinfection, while slaked lime is used for soil conditioning and nutrient supplementation.
Why do the neutralising effects of powdered limestone on soil last longer than that of slaked lime?
no
Explain the advantages of using slaked lime instead of powdered limestone for neutralising acidic soil?
Slaked lime is much more alkaline and effective at reducing acidity quickly - it is Ca(OH)2 whereas powdered limestone is CaCO3 and not as alkaline/basic. CO2 is also given off when the limestone reacts with the acid. Water is given of when slaked lime reacts. Mathematically it takes 100 g of limestone to 73g of HCl (as an example) where it would take only 74g of slaked lime per 73g HCl.

What property of slaked lime is important in neutralising acid soils?
The property of slaked lime that is important in neutralizing acid soils is its ability to react with acidic compounds in the soil, such as hydrogen ions, to raise the soil's pH. This helps to make the soil more alkaline and provides a better environment for plants to grow, as many plants prefer neutral to slightly alkaline soil conditions.
