Question

What would be the effect on plants if the soil’s pH increases?

(a) Nutrient absorption is reduced

(b) Nutrient absorption increases

(c) Soil contamination

(d) Soil fertility increases

This question was posed to me by my school teacher while I was bunking the class.

I would like to ask this question from Management of Alkali Soil topic in division Management and Remediation of Problem Soil of Environmental Biotechnology

Answer 1

Right answer is (a) Nutrient absorption is reduced

Easy explanation: There is disruption of nutrient absorption by the plants if it’s pH increases, and hence, soil fertility is reduced, alkaline soil’s pH doesn’t lead to increase in nutrient absorption, soil contamination doesn’t happen.
