| Abstract:
Several agricultural regions of the world suffer of an important hydrous deficit, the resources of water are then limited and it appears that considerations for present and future needs, and the agricultural value of wastewater become of first necessity. In this frame, the use of the treated wastewater is tested on irrigation of annuals crops in insertion with the olive-trees in the station of El Hajeb. Olive-trees gave an important yield and a high rate of oil, because they take advantage of this water richness in N. The effect of treated wastewater of chloride-sodic composition on the soil and on the olive-trees, particularly on development and on chemical composition in N of organs was followed in comparison with the not irrigated control. The results of chemical analysis and observations led us to point out that:
Otherwise, it is noted that in spite of the water contents in chloride-sodic, the olive-trees well known for their resistance to drought and salinity, do not show any sensibility in summer to the high rates of salinity and major elements in the soil. | |
