Answer:
Contour ploughing,building terraces that intercept and stop downward movement of soil. Netting is a temporary form of erosion control. Maintaining plant cover reduces wind speed. Growing crops in intervals across a field of cereals,and using trees and shrubs as shelter belts or wind breaks are also helpful.
Explanation:
The following measures can be taken to prevent soil erosion and ensure soil conservation: Terrace Farming - On hilly slopes, terraces act as bunds and prevent the soil from being washed away by running water. Terrace farming is practiced with successful results in Japan, South-East Asia and the USA.
Ploughing along the contour lines can decelerate the flow of water down the slopes. This is called contour ploughing.
Steps can be cut out on the slopes making terraces. Terrace cultivation restricts erosion.
Large fields can be divided into strips. Strips of grass are left to grow between the crops.

Different methods to check soil erosion are:
(i) Control overgrazing by livestock- Cattle,sheep,goats and other livestock tear up roots from the soil and ruining the texture and leave the land barren and exposed to wind and rain.
(ii) Mixed Cropping- it involves growing a variety of crops, mixed together. It is sown in rows or in regular intervals to prevent the soil from erosion.
(iii)Plant trees- Planting trees help to break wind and guard the soil against erosion. It also binds the soil with its deep roots and regulates the climate of a place by bringing sufficient rainfall.
