Question

A plant grow best when the pH of the is 7.2 but the pH of the soil is found to be 5.6 name the chemical (and it's nature also) that should be added to the soil to adjust it's pH to make it suitable for plant growth?​

Answer 1

Limestone should be added to soil for plant growth. It is alkaline in nature.

• Plant requires pH 7.2 for its growth, which states plant requires neutral pH conditions. The given pH of soil is 5.6, which is acidic.
• To neutralise the acidic nature of soil, alkaline compound namely limestone or calcium carbonate is added.
• The process of neutralisation occurs as acids react with calcium carbonate to release water, carbon dioxide and calcium salts.
