Immersion lifter developed to measure soil aggregates
Soil aggregates play a central role in soil science and are crucial for the functioning and productivity of soils. Wet sieving is a common standard method worldwide to distinguish aggregation. However, this work is often still carried out by hand or with improvised lifting mechanisms, which has some practical disadvantages.
In collaboration with the mechanical workshop at the University of Tübingen, the Soil Science and Geomorphology group has now developed a computer-controlled lifting mechanism that automatically performs the required movements in a highly standardised manner. The 3D-printed housing is equipped with an electric drive and can immerse three sets of sieves simultaneously in individually adjustable cycles. This reduces the workload and significantly improves the accuracy of the measurement.
The system will be used as standard upon completion of the new laboratory building. The design plans and possible applications will be published to enable other working groups to use it.
