In Gozo, local scientists are testing a new and innovative irrigation method that 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 this 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.
The new irrigation method is expected to have a significant impact on water conservation efforts in Gozo. By reducing the amount of water needed to irrigate crops, it can help address water scarcity issues on the island. The slow and steady release of water from the clay elements ensures that plants receive just the right amount of moisture, minimizing waste and optimizing plant growth.
Initial results from the pilot locations are promising, with crops showing signs of healthy growth and reduced water usage. If successful, this clay-based irrigation system could revolutionize farming practices in Gozo and beyond, offering a sustainable and efficient way to nourish crops while conserving precious water resources. Further research and testing will be conducted to evaluate the long-term benefits
