Question

Farmers neutralise the effect of acidity of the soil by adding what?

Answer 1

The most common way to raise the pH of soil is to add pulverized limestone to the soil.

Limestone acts as a soil acid neutralizer and consists of either calcium and magnesium carbonate or calcium carbonate

These are called dolomitic limestone and calcitic limestone respectively.

Answer 2

Farmers neutralise the effect of the acidity of the soil by adding a small amount of slaked lime or quicklime solution.

• Farmers neutralise the acidity of the soil to increase soil fertility. If the soil is acidic, it impacts not only the solubility of minerals but also the nutrients' availability.
• Calcium hydroxide is also referred to as slaked lime. Ca(OH)2 is its chemical formula.
• Slaked lime, which is a base, offers hydroxyl ions that help balance the acidity of the soil.
• The soil becomes acidic when there are too many sulphate or chloride ions present.
• Acidic soil harms plants by depriving them of nutrients due to poor root growth.
