| Abstract | ||||
| The study area covers 86337.1 hectares representing a vast region east of River Nile in El Minia Governorate. Its spectral signatures were recognized using remte sensing data of satellite TM8 aquiered in the year 2016. Land cover classes were defined as initiative study for detecting and outlying a promising area for agricultural land use, which was allocated as 50933.2 hectares. Physiographic soil units formed under erosion deposition processes are: a) Dissected rock land. b) Bajada with dominant soils of Sodic Haplocalcids, loamy skeletal, mixed, hyperthermic. c) Weathered rocky terraces having soils of Calcic Haplosalids, loamy skeletal, carbonitic, hyperthermic. d) Alluvial terraces, which are dominared by soils of Typic Haplocalcids, coarse loamy, mixed, hyperthermic E) Wadis include dominant soils of Typic Torrifluvents coarse loamy, mixed (calcareous), hyperthermic. Physiographic soil units formed by the deposition of meandering River Nile are: a) Point bar includes soils of Typic Torriorthents, fine loamy over sandy, mixed, hyperthermic. b) Bow bars having soils of Typic Torriorthent, coarse loamy, mixed, hyperthermic. c) Levees with soils of Typic Torriorthents, fine loamy, mixed, hyperthermic.d) Alluvial plainincludes soilsof Typic Haplotorrerts, clayey (fine), hyperthermic. Current land suitability of the non cultivated areas were evaluated for cultivating alfalfa, barley, cabbage, green pepper, maize, sesame, sorghum, tomato, potatos, wheat, citrus, date palm, guava and olives. This current suitability can be more profitable after executing the main growth limitations as salinity and sodicity expressing the potential land suitability. Supreme potential land suitability can be realized by shifting each crop to be adapted with certain physiographic unit for giving higher production. | ||||
