Healthy Olives Can Now Be Grown In Salty Water

Varieties of olive trees recently tested by researchers could be cultivated with moderate saline water irrigation.

The olive’s reputation as a health food is being borne out by modern science, as studies of olive-consuming Mediterranean peoples have shown. To keep the world’s olive lovers satisfied, an intensive wave of olive planting has occurred in the past decade in many parts of the world.

Traditionally, olives have been cultivated in the Mediterranean region. But fresh water is becoming increasingly hard to come by in semiarid areas, and irrigation of most new olive plantations is often accomplished with low-quality sources of water that contain relatively high levels of salt.

The relationship between the use of “saline water” and olive cultivation has been actively studied for many years. According to Professor Zeev Wiesman, Department of Biotechnology Engineering at Ben-Gurion University of the Negev, it is well-known that saline conditions can limit the development of olives, mainly because the salty water interferes with the olives’ root system and causes “toxic accumulation of chloride and sodium ions on the leaves.”
