Why do farmers use quicklime?
they use it to neutralise acidic soil in fields
How does alkali help to treat acidic soil?
A soil is acidic because there are compounds within it which dissolve in water to form an acid. An acid is defined as a substance which readily gives out protons to oter molecules. An alkali is the converse, in that it is a proton acceptor and readily takes on protons. Treating an acidic soil with an alkali would neutralise the soil, and so the soil would become less acidic. If enough alkali is added, the soil will become neutral, and it will become alkaline if even more alkali is added.
How does limestone neutralise the soil?
it sinks in
How do farmers neutralise soil?
Nitrogen enriched soil and chemicals are typically used as fertilizer to improve soil.
Is marshland soil acidic or basic?
Acidic
How do you neutralize soil after fertilized?
To neutralise a sample of soil, you must determine the pH of the soil sample either acidic or alkaline. Add lime (e.g. Limestone) to acidic soil to neutralise it. And add sulphur to alkaline soil which will neutralise it.

How do you make lawn soil less acidic?
Treating the lawn soil with agricultural lime will balance out the acidic properties. Lime is an alkali, and will neutralise the acidity.
Is Lime Basic?
lime is used on soil to neutralise its pH level form acidic so yes lime is basic.
Why neutralise soil?
water your soil
WHAT ACIDS and alkalis are in treatment of soil?
Well alkalies can be used when acid rain falls on farmland, a limestone powder is put over the field to neutralise the acid.
What is the pH value of ammonium sulphate?
While I can't find a specific pH value - it is certainly acidic - as it's used to 'neutralise' alkaline soil.
Why does calcium hydroxide neutralise soils that are too acidic?
Because Calcium Hydroxide is an alkaline and it acts as a base to neutralise the acidic soils and make them turn to pH7.

How do you neutralise acid rain in soil?
Add a base/alkali such as calcium carbonate (limestone) to the soil which will neutralise the acidity.
What do you understand by the term neutralise?
neutralise is making something neutral, so it isn't acidic or an alkaline eg. water
