$\huge{\fbox{\fbox{{\mathfrak{\red</h2><h2> {Answer}}}}}}$

Contour farming

• Contour farming may be defined as ploughing, seeding, cultivating and harvesting across the slope, rather than with it.

═════ ♢.✰.♢ ═════

Strip cropping

• On land with a dissected slope, planting crops on contour strips will be an effective erosion deterrent.

═════ ♢.✰.♢ ═════

Terracing

• The modern terrace is an embankment of earth constructed across a slope in such a way as to control water run-off and minimise erosion.

═════ ♢.✰.♢ ═════

Shelter belts

• These are the ‘green belts’ of trees which help to break the force of strong winds and thus prevent or cut to a minimum the blowing away of the loose topsoil. In areas where wind erosion is more, rows of trees may be helpful to check the flow of winds.
