The areas under Green Revolution technology are facing the problem of

  • A.gradual loss of soil fertility
  • B.increasing alkalinity and salinity of soils
  • C.chemical poisoning of soils
  • D.All of the above

Answer: D

The answer is All of the above.

Intensive Green Revolution farming in Punjab, Haryana and western Uttar Pradesh has caused each of these problems.

  • Loss of soil fertility: continuous rice-wheat cropping and heavy use of urea deplete organic matter and micronutrients such as zinc.
  • Alkalinity and salinity: over-irrigation and waterlogging bring salts to the surface.
  • Chemical poisoning: heavy use of pesticides and fertilisers contaminates soil and groundwater.

Since all three are real, choosing any single one is incomplete.
