Biology Question on respiration in plants
What is the best pH of the soil for cultivation of plants
A
3.4 – 5.4
B
6.5 – 7.5
C
4.5 – 8.5
D
5.5 – 6.5
Answer
5.5 – 6.5
Explanation
Solution
Fertile soil is rich in the essential minerals and nutrients required for healthy plant growth. Many of these minerals and nutrients exhibit greater solubility in soils with a slightly acidic pH compared to soils that are neutral or slightly alkaline. Soil with a pH ranging from 5.5 to 7 is particularly well-suited for supporting plant growth, earning it the classification of fertile soil. So, the correct option is (D): 5.5 - 6.5
