      Question

      ___ is the type of farming in which ridges and furrows

      formed across the slope build a continual series of small barriers to the flowing water which reduces the velocity of runoff and thus reduces soil erosion and nutrient loss
      A Contour farming Correct Answer Incorrect Answer
      B Strip cropping Correct Answer Incorrect Answer
      C Graded bunding Correct Answer Incorrect Answer
      D Hilly Farming Correct Answer Incorrect Answer
      E None of the above Correct Answer Incorrect Answer

      Solution

      Contour farming is one of the most commonly used agronomic measures for soil and water conservation in hilly agro-ecosystems and sloppy lands. All the agricultural operations viz. plowing, sowing, inter-culture, etc., are practiced along the contour line. The ridges and furrows formed across the slope build a continual series of small barriers to the flowing water which reduces the velocity of runoff and thus reduces soil erosion and nutrient loss.
