ABSTRACT
This experiment was undertaken in a newly reclaimed area at Badr district, Egypt to study the influence of a geotextile material under sprinkler irrigation on the availability of soil moisture content and salinity in the top 40 cm of the soil profile. The farm was planted by Navel orange from about ten years. To achieve the objectives of this research, the field experiment was carried out in order to measure soil moisture content, water distribution and different water relations (water application efficiency, water use efficiency and water stored efficiency) under sprinkler irrigation. The results indicated that the maximum fruit yield was obtained with mats placed at 20 cm depth whilst the minimum fruit yield was recorded with the control treatment. Mats at 20 cm depth increased the availability of soil moisture content in the root zone. The results further showed increases in water use efficiency and water application efficiency as a result of using the geotextile material. In addition, soil salinity in the root zone decreased as a result of increasing soil moisture content. As a conclusion, a geotextile mat is good and suitable for using under newly reclaimed areas to enhance the soil ability for catching of water
