Question

Ploughing along the contour lines to decelerate the flow of water down the slopes is called:
(a) Strip cropping
(b) Sheet erosion
(c) Contour ploughing
(d) Terrace cultivation

Answer 1

Answer:

C

Explanation:

Contour ploughing is the farming practice of plowing and/or planting across a slope following its elevation contour lines. These contour lines create a water break which reduces the formation of rills and gullies during times of heavy water run-off; which is a major cause of soil erosion.

Answer 2

(c) Contour ploughing

Explanation:

• Contour ploughing is a plowing activity on a slope while following its elevating contour lines. Such contour lines produce a water break that prevents the erosion of gullies and rills  in periods of heavy water discharge., it being the key cause of soil-erosion
• The water breaks often provide more time for water to settle in the soil. In contour plowing, the ruts that are formed by the plow run perpendicular instead of parallel to the slope, ensuing in furrows which curve through the land and are leveled. This process often avoids tillage erosion, which is the soil movt and erosion by the tilling of a  plot of land.
