Soil salinization is one of the most serious problems facing soil fertility, crop productivity and sustainable agricultural development in Egypt. The risk present, when it leads to toxicity. This study focuses on evaluation at East Nile Delta enhance management strategy program using geographical information system (GIS). Two different classifications salt-affected soils, agronomic classification Russian classification, were used. Ninety-two surface samples collected depth 0–30 cm. Inverse distance weighting (IDW) was used for spatial distribution mapping salinity degree. Normalized Difference Vegetation Index (NDVI) identify correlation between vegetation density cover levels. obtained data maps studied area presented that levels according occupied areas 60% – non-saline, 15% slightly saline, 13% moderately 2% strongly saline 10% extremely level. Nevertheless, degrees located 71% 10.5% slight 9% moderate 3.8% 5.7% very investigated area. On other hand, results showed reasonable NDVI, (EC) total toxic salts (%) (R2 = 0.58 with 0.65 salts). Finally, precise should consider concentration chemical composition salts.
