Question

Plants grow best when the pH of soil is close to 7.

• A. True
• B. False

Answer 1

The correct option is A

True

Plants grow best when the pH of soil is close to 7. Most nutrients that plants need can dissolve easily when the pH of the soil solution ranges from 6.0 to 7.5.

Below pH 6.0, some nutrients, such as nitrogen, phosphorus, and potassium, are less available.
When pH exceeds 7.5 iron, manganese, and phosphorus are less available.
