Abstract: Utilization of reclaimed wastewater (RWW) presents an alternative to irrigation of agricultural crops with fresh water (Fr), especially in dry areas characterized by water scarcity. While RWW often contains considerable amounts of valuable plant nutrients, it is also typically characterized by high salt content, which can impair agricultural yields and have environmental repercussions. The objective of this study was to determine the effect of long-term utilization of RWW and fertilization practice on soil properties and plant performance. We evaluated irrigation and nutrient management of olives with RWW versus Fr in a long-term field experiment. Two olive cultivars (Barnea and Leccino) were subjected to irrigation with RWW, either with standard or reduced fertilization, and irrigation with Fr with standard fertilization.
