As an effective technique for soil erosion control and fertility improvement proved by on site research and demonstration, contour hedgerow intercropping has been widely adopted by local officers and farmers.

Field experiments were conducted to test the effects of contour hedgerow system on slope croplands in Ningnan County, which lies in the dry and hot valley of Jinsha River in the southwestern Sichuan with more than 90 % of its rainfall in monsoon.

Mechanism and effect of different contour hedgerow types on runoff and sediment erosion in Three Gorges Reservoir Area;

Adopting contour hedgerow intercropping to control soil erosion in sloping croplands has an important impact on soil and water conservation.

Contour hedgerow intercropping as a type of agroforestry system,in which double-row hedges are planted along contour line in slopelands spaced 4-8 m,has been promoted for erosion control,soil fertility amelioration,and soil water storage in tropical mountain areas.
