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 it to neutralize acid soil to help crops grow
What do farmers put on acidic soil?
The farmers put lime water on acidic soil.
What do farmers and gardeners add to their soil if it is acidic?
lime water
How do farmers change the pH of soil?
the way that farmers change the PH of soil is by adding a little bit of lime or eggshells or oyster shells because they are all good ways to make it neutralize.
When to apply lime to soil?
Lime can be applied to the soil at anytime. You just have to make sure you do a soil test first to see how much lime is needed.
What substance is added to acidic soil?
quick lime or slaked lime is added to acidic soil
How can slaked lime be used by farmers and environmentalists?
farmers use it to neutralize acid soil to help crops grow
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
Why do farmers sometimes add slaked lime to acidic soil?
Many plants do not do as well in acidic soil. The lime makes the soil less acidic, or even basic.
Why must farmers be careful not to add too much slaked lime to soil?
the palnts might get boners
What do farmers use limestone for?
Lime (slaked lime or quick lime) is a strong alkali, and it neutralises the pH of the soil if it is acidic. It also contains valuable metallic elements needed for growing such as calcium, magnesium, iron, aluminum etc.
Why do the neutralising effects of powdered limestone on soil last longer than that of slaked lime?
no
What do farmers put on acidic soil?
The farmers put lime water on acidic soil.
What property of slaked lime is important in neutralising acid soils?
It is an alkaline substance, which neutralises the acid in the soil.
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 do farmers and gardeners add to their soil if it is acidic?
lime water
How do farmers change the acidity of soil?
They add lime to it so is editds the PH balance
