How is contour farming primarily practiced?

• A. By planting in straight rows on flat land
• B. By plowing and planting across the slope of the land
• C. By planting only in designated valleys
• D. By using synthetic fertilizers to enhance soil

Answer: (B)

Contour farming is primarily practiced by plowing and planting across the slope of the land. This technique involves following the natural contours and topography of the landscape, which helps to create natural barriers that slow down water runoff and reduce soil erosion. By planting crops in this manner, farmers can effectively manage water flow, retain moisture in the soil, and improve the overall health of the land. This practice is particularly beneficial in areas with hilly or sloped terrain, where traditional farming methods might lead to significant soil loss and reduced crop yields. The effectiveness of contour farming lies in its ability to harness the land's natural shape to achieve greater sustainability in agriculture.
