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.
