AGRO-ECOLOGICAL ASSESSMENT OF LAND SUITABILITY IN SOME WESTERN DESERTIC FRINGES IN EL-GIZA GOVERNORATE, EGYPT.

        An agro-ecological land quality evaluation of land suitability in some Western Desertic Fringes in El-Giza Governorate was determined using the MicroLEIS IP (Integrated Package), which included the assessment of land suitability for different agriculture crops (Almagra model). The geo-spatial distribution of the soil suitability in the studied area indicate that the barren areas which observed in the mapping units of WP1, WP2, WP31 and WV with total area of about 1307.9 km² have marginal suitable areas (S4 and S5) for all selected crops and fruit trees due to its high content of coarse fragments, the excessively drainage condition and the high content of calcium carbonate and salts; except olive which has moderate suitable (S3) in these areas. On the other hand, the mapping units of WP32, WP33, AW11, AW12, AW21 and AW22 are cultivated areas with total area of about 311.14 km² and have high  (S2) to moderate suitable (S3)  to cultivate all selected crops and fruit trees. Moreover, the mapping units of AW11 and AW12 have the optimum suitable (S1) to cultivate cotton. Also, the human activities in these areas improved the soil quality and suitability to cultivate many crops.
