TREATISE OF DIFFERENT PHYSIOGRAPHIC UNITS IN SINNURIS DISTRICT-FAYOUM GOVERNORATE – EGYPT

Sinnuris District is bounded by LakeQarun (north), Fayoum District (south), Tamia District (east) and Ibshwai District (west). The geopedological physiographic units and its taxonomic units of the studied area could be summarized as follow:
1. Fluvio-Lacustrine, moderately low terraces:
- Typic Torripsamments, siliceous, hyperthermic.
- Sodic Haplotorrerts, fine, smectitic, hyperthermic.
- Typic Torrifluvents, coarse loamy, mixed, hyperthermic.
2. Fluvio-Lacustrine, low terraces:
- Typic Torrifluvents, coarse loamy, mixed, hyperthermic.
- Sodic Haplotorrerts, fine, smectitic, hyperthermic.
3. Fluvio-Lacustrine, low terraces (basin cover with sand sheet):
- Sodic Haplotorrerts, fine, smectitic, hyperthermic.
- Typic Torrifluvents, fine loamy over sandy, mixed, hyperthermic.
4. Fluvio-Lacustrine, high terraces:
- Typic Haplotorrerts, clayey, mixed, hyperthermic.
5. Alluvial, moderately high terraces (basin):
- Typic Haplotorrerts, fine, smectitic, hyperthermic.
- Vertic Torrifluvents, fine loamy, mixed, hyperthermic.
- Typic Torrifluvents, fine loamy, mixed, hyperthermic.
6. Nile Alluvial, high terraces:
- Typic Torrifluvents, sandy, mixed, hyperthermic.
- Typic Haplotorrerts, very fine, smectitic, hyperthermic.
- Vertic Torrifluvents, fine loamy, mixed, hyperthermic.
7. Alluvial plain, Vales:
- Typic Torrifluvents, fine loamy, mixed, hyperthermic.
Data of land evaluation revealed that, soils under consideration, mainly, suffering from texture, salinity and sodicity, can be recorded highly suitable class with regard to potential suitability by application more suitable irrigation systems, favorable managements and cultivation appropriate crops.
More suitable crops follows the following descending order:
Sorghum > barley > cotton > olive > wheat > alfalfa > maize.
