Abstract
The aim of the current study area is to evaluate the soil sustainability depending on soil characteristics,(physical and chemical),to asses effect
land use changes on soil sustainability properties in west of Nile Delta using remote sensing data and to produce soil sustainability map of the study area. The investigated area was selected for soil sustainability assessment.The area located western Nile Delta west Alexandria Governorate, El-Nasser canal from the south and west, and Bahig canal from the south. It is bounded by 29º 27` 30`` and 29º 52` 0`` east, and latitudes 30º 45` 00``and 30º 57` 30`` North. It was geographically described, using a topographic maps(scale1:50,000), published by Land Survey Authority of Egypt (1990), with total area approximately of (177518 fed), having and elevation from 0 to 129 m above sea level. The water resources in the study area depend on El- Nasser canal from the south and west and Bahig canal from the south.According to the meteorological data; the study area is classified as
Mediterranean zone where evaporation rate, generally, exceeds the precipitation during some time of year.Sixteen soil profiles were dug to represent the different mapping units.The soil profiles were carefully described in site.The morphological description was carefully noted. Soil samples were collected for laboratory analyses. The soil analyses aimed to
evaluating its physical and chemical properties.The pedogenic process occurred in the study area as the development of diagnostic horizons, which were identified the soil as,gypsic, and calcic horizons. These horizons were inherited from their parent materials under the prevailing arid conditions
