Question

A fertile soil is likely to have a pH of:

• A. $3$
• B. $9$
• C. $5.5-7$
• D. $14$

Answer 1

Answer: (C)

$5.5-7$

Fertile soil contains sufficient minerals and nutrients needed for plant growth. Most minerals and nutrients are more soluble in slightly acidic soil than in neutral or slightly alkaline soils. The pH range of $5.5-7$ is highly suitable for plant growth and hence such soil is considered fertile.

Hence, the correct answer is option $C$
