Specific data from CropAnalyser

Share this item

Thanks to the CropAnalyser from Grimme, it is possible to estimate the amount of impurities. The new system records tuber size and the resulting potato yield during the harvesting process for specific varieties and subplots.


The CropAnalyser system is based on the laser light-section method, in which the entire crop flow is captured by a laser camera setup, above the bunker filling elevator.

 The collected data is automatically processed and visualized live for the operator of the machine and in the end customer portal “myGRIMME”. With the application “Fields” in myGRIMME, the user has the possibility to display the variation of tuber sizes, the resulting estimated yield as well as the percentage of trash. The “Crops” application enables a variety-specific assessment of the parameters.

With the aid of “agrirouter” (an internationally acting agricultural data exchange platform), the data from the CropAnalyser can be transferred in a standardized manner to further systems, such as farm management information systems (FMIS).

In practice, this means that important information for the disposition, storage and marketing of potatoes is immediately available online. As a result, unnecessary transport-capacity can be avoided and the planning of downstream processes can be simplified. In addition, the grower can check the success of agronomic measures and varieties from planting to harvest on the basis of valid data. In the following years, potato cultivation can thus be further optimized. In addition, the workload for manual yield sampling can be reduced by automatically recording the yield and tuber size.
