Turnkey Subsurface irrigation Fully Automated subsurface drip Irrigation
A 398-hectare subsurface drip irrigation project, commissioned in 2022, introduced state-of-the-art automation and engineering to open-field farming in Ukraine. Spanning eight irregularly shaped fields, the system incorporates advanced pumping, filtration, fertigation, and control technologies—providing efficient, long-term irrigation performance that was once exclusive to greenhouses, now utilized for corn and soy.
How We Made It Happen
Challenge
The project required delivering uniform subsurface irrigation across eight irregularly shaped fields, totaling nearly 400 hectares. Key challenges included:
• Managing water transport over long distances, including a 1.4 km span to the most remote plots.
• Ensuring stable filtration and precise fertigation under demanding flow conditions.
• Installing a reliable pumping system drawing water from a shallow open reservoir with only 1.5 meters of depth.
• Achieving full automation in an open-field context, where such levels of control are typically confined to protected agriculture.
Resolution
Metzer delivered a turnkey solution that integrates world-class technologies into a fully automated subsurface irrigation system. A central pumping station with five 75 kW pumps, controlled by frequency converters, ensures efficient water delivery. Filtration is managed by Amiad automatic mesh filters, with additional units installed near remote fields.
Fertigation is powered by automated plunger pumps and air-mixing systems, all managed from a single control room. The entire system—monitored by sensors, weather stations, and RTUs—is operated remotely via a Talgil controller and smartphone access. Water is distributed through PE pipes to ASSIF anti-siphon emitter dripline laterals, ensuring precise subsurface irrigation across all 398 hectares.
