How does contour plowing in farming help to prevent pollution?
wel

D) Contour plowing is used to reduce erosion and sediment pollution.

Explanation:

Contour plowing in farming helps to prevent pollution by reducing surface erosion of topsoil and preventing sediment pollution.

Contour plowing is a farming technique in which crops are planted along the slopes of hills or contoured areas.

  • The rate at which rain water and precipitation moves along slope terrain is very fast.
  • This causes the washing off of the the topsoil on hills to eroded very fast.
  • Contour plowing breaks the slope and farming is done along movement on the contour.
  • This prevents topsoil erosion.
  • It also prevents sediment pollution in nearby streams and water bodies that are located around the valley at the base of the hill.
