An innovative irrigation method being tested in Gozo by local scientists could drastically reduce the amount of water needed to irrigate plants and trees.
The clay-based system involves placing clay elements close to the crops' root zone. As the surrounding soil dries out, it creates a pressure differential and suction draws water out of the clay elements. The clay's specific porosity controls the rate of water release, ensuring a slow and steady flow that caters to the crops' needs.
Researchers led by the Eco-Gozo directorate within the Gozo Ministry are testing out the technology - a variation of a Self-regulating, Low Energy, Clay based Irrigation (SLECI) system that is also being piloted in Portugal and Morocco.
The initiative is being implemented in three pilot locations: the Government Experimental Farm in Xewkija, as well as two fields in Għarb and Xagħra. Researchers are specifically studying two essential crops: vines and citrus trees.
