ZIM Plant Technology GmbH

ZIM Plant Technology GmbH, an entity now operating under the umbrella of Yara International, specializes in advanced water sensor technology for the agricultural sector. The company was established in Hennigsdorf, Germany, with Professor Dr. Ulrich Zimmermann as the operational founder and Simon Rüger as CEO. It garnered early-stage support from High-Tech Gründerfonds in 2012, which recognized the firm's potential to address future resource scarcity. A significant milestone was its acquisition by Yara International in a deal announced in November 2013, aimed at integrating ZIM's sensor expertise into Yara's broader crop nutrition solutions.

The core of the company's business is the ZIM-probe, a non-invasive, telemetry-based magnetic sensor that provides real-time data on plant water stress. This device measures the turgor pressure within a plant's leaves, which is a direct indicator of its water status. The technology consists of clamping two small magnets on a leaf; one magnet contains a pressure sensor that transmits data wirelessly to a central controller. This controller then sends the information via a mobile network to an internet server, allowing farmers to monitor their crops remotely through laptops or smartphones. The system is designed for precision irrigation, enabling farmers to water crops exactly when needed, which can lead to significant water savings—reportedly up to 40-70% in some trials—and improved crop quality and yield.

The business model combines hardware sales with a service component, initially described as "Monitoring as a Service". Clients, primarily farmers and agricultural researchers in arid and semi-arid climates, purchase the probe systems and pay an annual service fee. The technology has been successfully deployed in various countries, including Spain, Chile, and South Africa, on a wide range of crops such as olives, grapevines, tomatoes, and citrus fruits. By providing precise, plant-based data, ZIM Plant Technology helps optimize irrigation schedules, reduce water consumption, prevent soil salinization from overwatering, and ultimately enhance the profitability and sustainability of farming operations.
