Question

What is the optimal soil pH for most plant growth? Why is this so?

Select one:
A. 4-5, due to the fact that the majority of soil nutrients are only present at the this pH
B.6-7, due to the fact that the majority of soil nutrients are soluble at the this pH
C. 9-10, due to the fact that the majority of soil nutrients can be absorbed by roots at the this pH
D. 6-7, due to the fact that the majority of soil nutrients are created in soils with this pH

Answer 1

B

Step-by-step explanation:

6.0-7.0 pH is important because most horticultural crops will grow satisfactorily in these levels. It also influences the amount of pH available in the soil, like answer B states.
