Résumé
The current work was implemented to introduce an exclusive description for the reclamation of an area equivalent to 50459.04 hectare situated along El Bahria Oasis Road – Giza Governorate. GIS and RS techniques were implicated in this study. A soil survey was carried out where the main physical, chemical properties and fertility parameters were engaged. The studied area was classified into ten family under two orders ; Aridisols and Entisols. Geographic database for the soil properties and nutrients under study were built up and digital maps were produced. Land evaluation was done according to Storie & Sys and others : Land capability of the studied area showed four classes namely ; II, III, IV and V).The land suitability for twenty one different crops:winter crops [i.e.,wheat, barley, alfalfa, onion, potato, sugar beet and pea] ; summer crops [i.e., maize, sorghum, sesame, groundnuts, sunflower,tomato, cabbage, watermelon and cotton] ; orchard trees [i.e. grapes, mango, olive, citrus and date palm] were appraised for the area under investigation and exported to GIS to be displayed in digital maps. Actual Fertilizer requirements for suitable crops were estimated ; spatial analyst tools in Arc/GIS were used to create digital maps for such the requirements were calculated in form kg /hectare as, N, P, K units, taking into consideration the actual content of the nutrient found in soil.The resulted fertilizers needs maps are considered very potential for precision farming application.
