In: Mansoura University Journal of Soil Sciences and Agricultural Engineering 2013.v.4(8)Summary: In this research, wadi El-Farigh area western desert, selected as a case study site, which considers one of the high priority regions for future development agriculture in Egypt. Based on ENVI 5.0 and Arc Gls 10.1 using ETM+ land sat 7 to producing physiographic map for studied area. The mapping units were representative by eight a physiographic units of high decantation basin, low decantation basin, high Aeolian terrace, low Aeolian terrace, high over flow basin, low over flow basin, high sand sheet, low sand sheet. A total of 16 soil profiles representative the physiographic map units, were dug and descripted. The dominate texture is sandy, EC (ds/m) range between (0.46- 6.8) , CaC03% content ranged between (1.45-13.6), ESP% range between (5.14- 6), CEC range between (3.68- 5.44meq/100g) depth of soil profile ) range between (45- 135 cm ) organic matter (0.35-0.54 %) available nitrogen range between (11.32 - 40 ppm ) available phosphorus range between (5.6 - 20.2 ppm) available potassium range between (10.9- 49.52 ppm ).
