Question

A plant grows best when the pH of the soil is7.2.

But the pH of the soil is found to be 5.6.Name the

chemical (and its nature also) that should be added to

the soil to adjust its pH to make it suitable for plant

growth.​

Answer 1

Answer:

Elemental sulfur may be used to acidify alkaline soil to the desirable pH range. It may also be used to maintain pH in the desirable range, on soils that tend to become alkaline with management. When elemental sulfur is applied to soil, it combines with oxygen and water to form sulfuric acid.
