| Abstract | ||
| In Toshka, south of Egypt, the extremely arid conditions reflect vast areas covered by the aeolian deposits. To control the shifting sand along El-Sheikh- Zayed canal, which convey water to the newly reclaimed land, an experimental pilot area was established . In such area, four plant species were cultivated as a shelterbelt and arranged in plots including different plant distributions of variable spacing. The results achieved show that the shelterbelt plays an important role in the control of shifting sand. The shelterbelt enhances the deposition of the aeolian sand at a reasonable distance from the irrigation canal. The reduction percentage of shifting sand down wind the different plots of shelterbelt varied from 70.9 to 90.8 %. The plot of four rows of Acacia saligna and one row of Tamarix articulata as well as the plot of four rows of Prosopis juliflora and one row of Tamarix articulata show the highest efficiency for sand encroachment control . The above mentioned two designs are recommended for large scale application. | ||
