Abstract
Shortage in Nile water resources resulted in using the unconventional sources of water such as drainage water. The Current study is carried out in Kom Oshim district, Tamia, El Fayoum Governorate which was selected to study the soil health in 6 sites: four of them were cultivated with Olive trees in different times and irrigated (DROP irrigation)with a mix of agricultural drainage water and Nile water obtained from the mixing stationlocated at Kobry el Bayomy, Tamia District. Themixing station mix the drainage agricultural water and the Nile water in a ratio of 3:1. The fifth site (control site) was free of plantation (virgin soil) without irrigation. The sixth site located at Al Alam district, Sanours, El Fayoum Governorate irrigated (basin irrigation) with Nile water from Bahr Alaam only for more than 50 years ago and cultivated with alfaalfa crop, was used for comparison. Soil samples were collected during spring, summer and autumn of2012 from all sites at 30 cm depth of the soil surface from rizhospher area of plantations. Each sample was about 1 Kg there were three samples of each site. Each site samples were mixed together and divided into two volumes and preserved in icebox. One volume is for physical and chemical analysis whiles the other one is for determination of soil fauna.
