Résumé
Desert land is subject to severe wind erosion. Meanwhile, blowing of winds creates many other problems including the formation of shifting sand sheets and sand dunes that may occur also on Agricultural land, traffic lines. These present the main constraints affecting reclamation and settlement activities as well as other strategic movements. Confineting such adverse influences may be carried out through the establishment of wind screens. mechanical- and in particular biological fixation. Advantages of biological fixation under desert conditions include ; effective long-term protection against wind ; effective protection of the ground, the plants being a natural and homogenous sand-trapping system positive influence on the ecology of the respective area (e.g. soil moisture and micro-climate) ; potential source of income by controled grazing, fuel wood extraction etc .. The present study was designed to measure the performance of Acacia saligna, Atriplex nummularia, Panicum antidotal , Prosopis juliflora & under the prevailing station, In Sinai. conductded to study Agave sisalana in fixing drift sands conditions of Wadi Sudr experimental In addition a pot experiment was the capability of such species to withstand different concentrations of salts in irrigation water.
