Abstract
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.
Key words: Soil nutrients status, land capability and suitability, crop fertilizer requirements, fertilization maps, Arc/GIS technical.
