Abstract

The current work was carried out at El-Sheikh Zewied, Agricultural Experimental Station of the Desert Research Center, North Sinai Governorate, to study the infiltration rates and other soil physical and chemical properties and their relation to irrigation schedule in the wind eroded areas. The area are divided into three zones, eroded zone, transport zone and depositional zone, each zone included three infiltration tests and three soil profiles, the distance between each test is about 50 m along the wind direction, the second zone (transport) is about 500 m from the first zone (eroded) and the third zone (depositional) is about 1500 m apart from the second zone.
Results show that the infiltration rates decrease gradually along the wind direction and the coarse sand fraction of soil texture also decreases gradually along the wind direction, while the reverse is true with fine sand fraction of soil texture. Similar trends were obtained with electric conductivity dS/m and cations and anions concentrations. Also, the obtained results show that for irrigation frequencies, of coarse and medium sand textured soil, watermelon, tomato and peaches can be grown satisfactorily using sprinkler or drip irrigation, except for barley and olives. In case of fine sand textured the irrigation frequencies are larger than 9 days, surface irrigation under special conditions was applied for all crops, in spite of the high intake rates.
