Means of soil conservation include erosion control, such as contour ploughing,
strip cropping, ridging, and terracing. Ridging and terracing were discussed
above; the practice of contour ploughing, even though mentioned, merits a more

Drought Management on Farmland
CONTOUR PLOUGHING Contour ploughing ranks high as a simple, cheap and
effective way of conserving rain where it falls, on slopes of about 2-8 per cent.
Both by increasing the roughness of the surface and by creating small retaining ...
Use contour ploughing Look at Figure 7. The top part shows that the ploughing
has been done so that ridges run down the hill. You can imagine what will
happen! (see Investigation 7.) In the bottom part of Figure 7 the ploughing has
been ...
M.B.V. Roberts, June Mitchelmore, 2000
One of the most widely used of such methods is contour ploughing, which
involves following the level of the land, rather than ploughing up and down
slopes in a manner that tends to channel runoff. The method can be
supplemented by ...

Soil Tillage in Africa: Needs and Challenges
Much accurate (but site-specific) data are available for contour ploughing (
Hudson 1962; Elwell 1971; Elwell and Stocking 1988; IAE 1989-90; Vogel 1991a
). Typical estimated values of average annual losses of soil, water and nutrients
for two ...

Atlas of the Ethiopian Rural Economy:
Contour ploughing, whether by hand or using animal traction, can significantly
mitigate soil nutrient losses due to erosion. The steeper the slope of cultivated
land, the more important this practice becomes. Nationally, 44 percent of holders

Soil Conservation and Silviculture
Data on the reduction of erosion intensity, the increase in the water reserve in the
soil and the reduction of surface runoff as a result of contour ploughing are all
shown in Tabs. 40 and 41. Table 40 Effect of the method of soil cultivation on ...
