Abstract
SUMMARY AND CONCLUSION
The current study was carried out on some soils west of Kom Ombo County; it located east of Cairo-Aswan desert road, and south of Banban road, at 18 Km west of Kom Ombo city, and 50 km north of Aswan city, at the western desert. The area lies between latitude 24° 24’ 51”N to 24° 22’ 41.4” N and longitude 32° 45’ 56” to 32° 47’ 21.22” E. The total area understudy covers about 3250 feddans.
The study aimed to give some information about the physical, chemical and morphology properties of the soils. Based on the obtained data soil land capability for irrigation and land suitability for main crops were also accomplished using the Automated Land Evaluation System (ASLE) and (Arc GIS 10.2) .
Fifty four profiles were dug to the suitable depth, according to the type and nature of soil material. Soil samples were taken for each layer of soil profiles (124 samples) for necessary analysis after morphological description of each profile.
Data obtained could be summarizing as it follows:
A- Physical and chemical properties:
1- Most of soils in location understudy are coarse in texture (sandy loam, loam and loamy sand); these poor values of fine particle texture percentages reflect the sand texture of the soils of the western desert.
2- The saturation percentage (SP) was varied between 14.6 and 36 %.In most cases, soil saturation percentage values coincide well with the clay and silt content.
3- Soil Particle density, bulk density, porosity of the studied soil samples, particle density ranges between 2.33 and 2.70 Mg/m3 and soil bulk density is ranges between 1.23 and 1.91 Mg/m3. While, porosity ranges between 26.70–47.21 %, most value of the soil bulk density decrease through the soil profiles While, most value of the soil particle density increase with depth.
4- Soil reaction (pH 1:1 susp.) varies considerably between 7.34 and 9.46, indicating slightly alkaline to strongly alkaline soil reaction. In most cases, the surface layers have considerably higher pH values than the subsurface ones, also be noticed, that no clear pattern of pH changes occurs either within each profile.
5- Soil salinity (ECe) values in general vary between 0.39 dSm-1 and 59.32 dSm-1. Most values of soil salinity (ECe) are salt free (62.1 %) of total area. In most cases, Electrical conductivity is increase with depth, the lowest values of ECe are also found in the surface layers of profile.
6- Soluble cations are dominated by sodium and magnesium followed by calcium then potassium. Soluble anions are dominated by chlorides, in most of studied soil samples, followed by sulfates, then bicarbonates.
7- Total carbonates (CaCO3) ranged between 0.49 and 5.77 %.
