Question

Gardeners understand that plants have specific pH requirements. Most plants thrive in soil with a pH that is slightly acidic, neutral, or slightly basic. Imagine your soil is very acidic, with a pH of 3.5. How can you raise the pH to an appropriate level so your garden plants will survive?

A) Add fertilizer.
B) Water frequently to wash away the acid.
C) Add organic matter like peat moss or humus.
D) Add a base like limestone or calcium carbonate.

Answer 1

Answer:

D) Add a base like limestone or calcium carbonate.

Explanation:

-To reduce the soil's pH, you need to add an alkaline or base solution.

-Calcium carbonate has an alkanizing property and forms a carbonic acid and calcium hydroxide when dissolved in water.

-The solution will reduces the soil's pH.
