Q: How can we control water logging in agricultural land?
  • A. By increasing the intensity of irrigation
  • B. By lining of canals
  • C. By closing the nearby natural drains
  • D. By avoiding crop rotation
Correct Answer: Option B - An agricultural land is said to be water-logged, when its productivity gets affected by the high water table. • Water logging control– (i) Lining of Canal and Water Courses. (ii) Reducing the Intensity of Irrigation. (iii) By introducing crop-rotation. (iv) By provisions of an efficient drainage system. (v) By adopting consumptive use of surface and subsurface water.
