Nutrients to the point: RAUCH redefines fertilisation in special crops with SpotSpreading

• RAUCH introduces SpotSpreading, a sensor-based fertiliser application system that targets individual plants with high precision.

• Ultrasonic sensors detect tree positions in real time to apply fertiliser only to the root zones, optimizing nutrient use.

• The system integrates with RAUCH's MDS twin-disc spreader and ISOBUS control for automated, adaptable operation.

• SpotSpreading can reduce fertiliser use by up to 44%, lowering costs and CO2 emissions significantly without affecting yields.

With the SpotSpreading metering system, RAUCH Landmaschinenfabrik GmbH presents a sensor-based innovation that adapts fertiliser application in special crops specifically to each individual plant. Ultrasonic sensors detect the position of trees in real time, whereupon the machine opens the metering slides fully automatically and only supplies the root area of the plants. This high-precision process is controlled by an intelligent control unit that algorithmically evaluates the driving speed, sensor distance and desired fertiliser radii and controls them according to requirements.

At the heart of this innovation is a sensor system that applies granulated mineral fertilisers or organic pellets only where plants can effectively absorb them, directly in the root area of the tree. This is made possible by ultrasonic sensors attached to both sides of the machine, which scan the terrain up to eight metres to the side. As soon as a tree is detected, the control system calculates the optimal time to open and close the metering slide, taking into account the driving speed, sensor distance and disc position.

A specially developed control programme also allows the exact fertiliser radius around the trunk to be specified – a measurement based on the root structure of the respective tree species. This results in dynamic, tree-specific application – fully automated and highly efficient.

Technological integration at the highest level

The system is based on the proven RAUCH MDS twin-disc fertiliser spreader in combination with an ISOBUS control system. This processes sensor data in real time, regulates metering slide positions and ensures that the desired application rates are maintained at variable speeds. The ability to apply both conventional mineral and organic fertilisers with precision underlines the versatility of the system.

Economic and ecological advantages in figures

The potential of SpotSpreading is impressive. Under typical operating conditions – approximately 6 m tree spacing and 5 km/h driving speed – up to 44% of fertiliser can be saved. Across all applications, this results in an average reduction of 23%, which not only benefits operating costs but also significantly reduces environmental pollution. Based on 1.3 million hectares of European orchards, this corresponds to CO2 savings of 43,000 tonnes per year, with no change in yield.

Technological advancement from RAUCH

With SpotSpreading, RAUCH impressively demonstrates its innovative leadership in the field of fertiliser application in special crops. By combining intelligent sensor technology, software-supported dosing logic and practical machine integration, the company once again proves its expertise in realising future technologies that are market-ready and user-friendly. In a market environment that demands both efficiency and sustainability, SpotSpreading sets new standards – both economically and ecologically.
