Challenge

In sugar beet cultivation, precise yield mapping has not been possible to date. While the current technical equipment of beet harvesters measures the fill level in the machine, this data is not precise enough under all conditions. How much has been harvested where in the field? This is important information, among other things, for the targeted and economical use of fertilizers. The transport chain from the field to the sugar factory could also be organized more resource-efficiently with accurate quantity data.

Solution approach

Currently, the fill level of the beet bunker is recorded using ultrasonic sensors, which, however, can only determine the volume and not the mass and are rather inaccurate. The KibEZ project is testing a solution based on artificial intelligence (AI) that is intended to be usable in the long term on different machine types from various manufacturers. Machine parameters and measurements such as power consumption during cleaning are used and evaluated with other data, such as soil type, etc., using AI. To do this, the AI must learn to draw the right conclusions through extensive calibration trials and derive accurate yield maps from them.

To create such a system, the project partners must bring their expert knowledge together: The practical experience from agricultural practice is just as necessary as the cooperation of the harvesting machine manufacturers, the exact execution and documentation of the trials, and not least the selection and implementation of the algorithms and the training of the AI.

Results

In the KibEZ project, an AI-based approach for determining sugar beet yield was developed and validated. A training dataset with approx. 16,000 m² at ten locations and a validation dataset with 32 complete bunker loads were created. On this basis, an AI model was developed that determines the beet yield solely from process data of the beet harvester. The results show a correlation between machine data and beet yield and enable yield information without additional sensors. Detailed information in the final report.
