In a significant advancement for sustainable agriculture, researchers from the University of Patras in Greece have developed a groundbreaking IoT-based irrigation platform designed specifically for olive groves. This innovation, detailed in the recent publication in ‘Smart Agricultural Technology’, leverages Low-Power Wide-Area Network (LoRaWAN) technology to optimize water usage in a sector that is often criticized for its high water consumption.
Lead author Aglaia Liopa-Tsakalidi explains the project’s motivation, stating, “Irrigation is crucial for crop productivity, but it can also lead to significant water wastage. Our goal was to create a system that not only conserves water but also enhances the yield of olive crops.” The prototype was implemented in a 22-hectare olive grove in Peta, Greece, specifically focusing on Kalamon olives, a variety renowned for its quality.
The platform employs low-cost microcontrollers and embedded sensors to monitor soil moisture levels at various depths—30 cm, 60 cm, and 90 cm. These IoT end nodes operate on battery power for extended periods, transmitting data over distances of up to 15 kilometers through a single LoRaWAN gateway. This secure and efficient data transmission is vital for real-time monitoring, which is facilitated by a cloud-based infrastructure that allows farmers to access crucial information via online dashboards.
The results from the initial implementation have been promising. Water consumption was reduced by 42% in 2020 and 25% in 2021, demonstrating the platform’s effectiveness in promoting sustainable irrigation practices. “Our system not only provides real-time data but also helps in making informed decisions about irrigation strategies,” adds Liopa-Tsakalidi. “This is essential for maximizing water savings while ensuring the health of the crops.”
The integration of a robust software development system allows for centralized data management, enabling farmers to conduct trend analysis and optimize cultivation practices. The platform’s use of Docker for flexible deployment ensures that it can be easily adapted to various agricultural settings, making it a versatile tool for the industry.
As the agricultural sector grapples with the challenges posed by climate change and water scarcity, innovations like this IoT-based irrigation platform could reshape the future of farming. By harnessing the power of technology, the water, sanitation, and drainage sector stands to benefit significantly. Not only does this research pave the way for more sustainable agricultural practices, but it also highlights the commercial potential of IoT solutions in enhancing operational efficiency and resource management.
