Abstract


The current work was implemented to introduce an exclusive description for fertilization of an area equivalent to 50459.04 hectare situated along El Bahria Oasis Road – Giza Governorate, Egypt. GIS and GPS techniques were implicated in this study. Soil survey was carried out where the main physical, chemical properties and fertility parameters were engaged. The studied area was classified into 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 with respect of storie). The land suitability for some crops (winter crops, summer crops and orchard trees) were appraised for the area under investigation and exported to GIS to be displayed in digital maps. Taking into account the contents of the nutrients present in soil the Fertilizer requirements for suitable crops were estimated; spatial analyst tools in Arc/GIS were used to create digital maps for the requirements of key figures nutrients (N, P, K) calculated in kg /hectare; The resulted map for fertilizers needs could be considered of enormous potential for precision farming application.

*2016 Journal Impact Factor was established by dividing the number of articles published in 2014 and 2015 with the number of times they are cited in 2016 based on Google Scholar, Google Search and the Microsoft Academic Search. If ‘A’ is the total number of articles published in 2014 and 2015, and ‘B’ is the number of times these articles were cited in indexed publications during 2016 then, journal impact factor = A/B.
