Abstract
Objectives: The principal objective of this research is to identify the land use for each defined land map unit taking into account the physical properties considerations as well as the sustainability of environmental resources of some soils in Nile Delta area. Methods & Results : The studied area is located between 31◦ 15΄ to 31◦ 30΄ E 31◦ 15΄ to 31◦ 30΄ N (total area about 659 km2) in Dakahlia governorate (Bilqas city) On the basis of the topographic nature (Military survey maps) (1: 50000) namely, sheets of Elgarida eighteen soil profiles were selected from these regions representing the different soil types. Landsat Enhance Thematic Mapper (ETM) have been used for delineating and mapping the studied area. data had to be incorporated. This was done using Geographic Information System GIS. he studied area was grouped into three main physiographic unit: Front shore of coastal plain which form about 3.86% of the studied area (6052.3 fed.). It includes one soil map unit (SMU2). Back shore of low-lying stretches which form about 29.58% of the studied area (64632.4 fed.). It includes tow soil map units (SMU4) which form 23.87% of the studied area (37476.4 fed.) and (SMU2) which form 5.71% of the studied area (8956.0 fed.). Old deltaic plain which form 63.24% of the studied area (99303.9 fed.). It includes six soil map units (SMU1) which form 12.51% of the studied area (19.645.1 fed.), SMU3 (20.26%, 31807.4 fed), SMU5 (3.78%, 6081.4 fed.), SMU6 (7.47%, 11728.4 fed.), SMU7 (9.86 %, 15484.4 fed.) and SMU9 (9.27%, 14557.0). Conclusion: It can be concluded that soils in the studied area are poorly developed according to soil pedology, where no obvious diagnostic horizons were observed. Accordingly, soil orders in the studied area were Entisols and Verisols. The studied area could be classified into three physiographic units Front shore of coastal plain which form about 3.86% of the studied area, Back shore of low-lying stretches which form about 29.58% and Old deltaic plains which form 63.24%
