Q: Which of the following factors is not responsible for the loss of fertility of agricultural land?
  • A. Salinisation of soil
  • B. Higher cation exchanger capacity of soil
  • C. Alkalisation of soil
  • D. Waterlogging
Correct Answer: Option B - The salinisation of soil, alkalisation of soil, waterlogging lead to the loss of fertility of agricultural land. Cation exchange capacity (CEC) is a measure of the soil's ability to hold positively charged ions. Higher the CEC then higher will be its fertility. Hence its not a factor of losing of soil fertility.
