EGYPTIAN SOILS AND PLANT EFFECT OF DRAINAGE WATER ON SOME

Abstract

Field study was carried out to evaluate the effect of a long term irrigation with waste water on soil properties and content of macro and micro nutrients and heavy metals as well as cultivated plants. Therefore, four locations were chosen at Zenien area and the control from outside the study area, El- Giza Governorte. These irrigation sources were differing in its quality, including sewage wastewater, secondary treated sewage water, canal polluted water, well water and normal fresh water (control). The soil texture is clay and the tested crops were Berseem and Zea Maize. A salinity and heavy metals accumulation problems were found in soil as well as cultivated plants in long run application. The concentration ratio of the (N, P, K, Fe, Cu, Zn, Mn )was higher in soil irrigated with "SWW, STSW, CPW, and WW'' in companson with those irrigated with normal fresh water (control). A gradual decrease in heavy metals with increasing soil depth. There is an increase of macro . micro nutrients and some heavy metals content in plant shoots, a high accumulation ratio of these elements was found. A high transfer cocrticicnt or these metals to plant shoots from soil was round. An increase oi' macro, micro nutrients and some heavy metals content in Maize grains was found in comparison with those obtained with control due to irrigation with low quality water.
